MINELAB’S UNIQUE TECHNOLOGY
The Explorer is the first of a new generation of detectors from Minelab. Its sleek, sturdy
design, innovative control panel and comprehensive targeting options set it apart from
any other detector available today.
MINELAB’S UNIQUE TECHNOLOGY
Two mode detecting
The Explorer is so feature-packed that the research team at
Minelab decided to offer two modes of operation: fully automated
detection (Quickstart mode) and personally customized precision
detecting (Advanced mode).
All of the detector’s vital functions are common to Quickstart and
Advanced mode. Because the Explorer is such an innovative
machine, even the seasoned treasure hunter will benefit from
beginning in Quickstart mode.
Quickstart mode
As soon as you have assembled the Explorer, you are ready to
start detecting. When it leaves the factory, the detector is
programmed to start in Quickstart.
Quickstart settings are optimized to provide you with accurate
detection in most conditions you will encounter in the field, so you
can concentrate your attention on the objects you discover.
This manual’s Chapter 4: Control Panel, outlines all of the control
panel features needed to use your detector in Quickstart (or
Advanced mode) including shortcut buttons, special functions like
Pinpoint and adjusting your detector settings.
Chapter 5: Quickstart, explains basic use in detail and provides
tips on everything from sweeping the detector coil to digging up
objects.

MINELAB’S UNIQUE TECHNOLOGY
The Full Band Spectrum (FBS) circuit automatically transmits 28
frequencies simultaneously. This increased frequency range means
that the signal received from the detector coil is analyzed from a
wide range of responses. This information is relayed to the operator
via the speaker or headphones and the control panel’s liquid crystal
display as an audio or visual target response.
Put simply, Minelab’s unique FBS technology means deep, sensitive,
accurate detecting.
Ground Compensation
The Explorer uses a sophisticated approach to the elimination of
ground mineralisation. It uses advanced digital filtering to eliminate
the influence of ground signals.
You are now ready to proceed to Chapter 2: Assembly.
Operating Frequencies
A metal detector’s
electromagnetic operating
frequencies are measured in
kilohertz (kHz).
Low signal frequencies
(e.g. 1.5 kHz) penetrate
deepest, but sensitivity to
smaller targets is low.
On the other hand, higher
frequencies have a more
shallow depth of penetration
but high sensitivity to small
targets.
The Explorer’s multiple-
frequency operation provides
the advantage of both.
THE MINELAB EXPLORER

INTRODUCTION

www.minelab.com
Full Band Spectrum (FBS)
When developing Full Band Spectrum (FBS) technology, Minelab’s
scientists looked at improving the already successful Broad Band
Spectrum (BBS) technology used in previous Minelab detectors.
Discussions with seasoned treasure hunters from around the world
identified a number of possible enhancements for operators. The
improvements to the Explorer detectors include:
• increased detection depth;
• accurate identification of targets to greater depth;
• enhanced detection of desired targets amidst iron trash;
• adjustments to improve operation for searching salt-water
beaches.
Most detectors on the market
operate on a single (or dual)
frequency, ranging from 1 to 70
kilohertz (kHz). Although this
technology has served the industry
well for years, Minelab’s scientists
found that a frequency that worked
well in one area would often offer
only marginal performance when
used in another location. Ground
mineralisation, trash content, and
target size all had an effect on how
effective a detector transmitting a single frequency would operate.
Full Band Spectrum technology combines Minelab’s existing multiple
frequency BBS technology with a powerful new microprocessor to
give:
• greater detecting depth;
• consistent sensitivity over a wide range of targets;
• less interference from electromagnetic sources;
• more accurate identification of target characteristics.
MINELAB’S UNIQUE TECHNOLOGY
Discrimination
Discrimination is the ability of a
metal detector to identify the user’s
desired target (e.g. jewelry) and
eliminate signals from undesirable
material (e.g. nails).
The Explorer can be programmed in
a number of ways to discriminate
against unwanted targets in
different types of ground.

STEP 4 (Figure 2.16) Gently pull the coil cable from the channel
underneath the lower shaft.
STEP 5 (Figure 2.18) Loosen the yoke nut and carefully remove the
bolt from the yoke bracket. This removes the yoke from the
search coil. Be careful not to lose the two plastic washers.
STEP 6 Replace the search coil. Be careful not to damage the
thread of the nut by over-tightening.
STEP 7 (Figure 2.17). Starting at the top of the lower shaft, carefully
feed the coil cable back into the channel at the rear of the
lower shaft so that the curled cable is in line with the shaft.
There should be to inch (3-5mm) of cable exposed
between the cable curls and the start of the lower shaft. Once
this is completed you should be able to see approximately 6
inches (150mm) of cable between the coil yoke and the
search coil. This is the slack necessary to allow adjustment to
the angle of the search coil.
STEP 8 To replace the coil cable access panel ensure that the
coil cable aligns with the semicircular hole at the side of
the coil yoke and gently ease the coil cable access panel
into the top of the recess until its prongs are well within
the recess. Check again to ensure that the cable is snugly
lodged in the semicircular hole.
STEP 9 (Detail in Figure 2.15). Using a screwdriver in the slot, prize
the panel back flush into place.
STEP 10 Reconnect cable to control box (as directed in
Connecting the shaft assembly, page 16).
NOTE If you have difficulty retrieving coil cable from
within the upprt shaft it will be necessary to shorten the
overall shaft length to allow the necessary slack.

Battery life indications
Figure 3.4
Visual indication – The battery life indicator appears on all of the
Explorer detect screens. The battery will be fully shaded at
maximum battery charge. When this shaded area nears the bottom,
the detector will begin to sound its low battery warning.
Audio indication – When the alkaline or NiMH batteries
approach the point at which they do not supply enough power to
operate the Explorer, a falling extended chord is emitted from the
speaker (or headphones). When this low battery warning is heard,
there will be only a few minutes of life left in the batteries. It is
recommended that the batteries be replaced or recharged as soon
as possible to avoid missing any targets. When the battery symbol
is completely empty, the detector will sound an extended ‘dropping’
tune and display a message immediately before turning itself off.
Notes supporting performance figures
Alkaline batteries will power the Explorer for up to 14 hours of
constant use. The NiMH battery pack will power the detector for up
to 11 hours of constant use. Battery performance is charted in
Chapter 7: User Info.
NOTE Unlike Nickel Cadmium batteries, the NiMH battery
pack DOES NOT have to be flattened to be recharged.
Whenever the detector has been unused for a lengthy
period, recharge the battery pack to ensure full
performance. There is no limit to the time the battery pack
can be left on charge.
You are now ready to proceed to Chapter 4: Control Panel.

Recharging NiMH battery pack with the car charger
The Explorer XS is provided with a car charger that boosts the
voltage of the car battery (usually about 12V) to a voltage
sufficiently high to charge the NiMH battery pack.
STEP 1 Remove battery pack as per instructions on page 24.
STEP 2 Insert the car charger plug into the cigarette lighter socket.
STEP 3 Insert the car charger plug into the socket at the tapered
end of the battery pack. A small light on the car charger
illuminates indicating that the car charger is in operation.
NOTE Some vehicles will need the ignition to be switched on
to ‘accessories’ for power to be supplied to the charger.
STEP 4 Leave the battery to charge for about 16 hours for a
complete recharge. If the battery was not completely
discharged, the charging time will be shorter.
The car charger is provided with a 3AG 2Amp fast fuse for short
circuit protection that can be accessed by unscrewing the tip of the
cigarette lighter plug.
NOTE Charging the battery beyond full capacity will not
damage the NiMH battery pack, but it could gradually
discharge your car battery.

BEGINNER USE
Trying out the detector
Figure 5.2
Don’t try this at home!
If you attempt to begin detecting while you are inside your home,
you will quickly find that there are many metallic objects (such as
nails or reinforcing in the floor) which will result in almost
continuous detection. There will also be interference from TV sets
and other household appliances. Placing the sensitive detector coil
near large metallic objects can result in temporary saturation of the
sensor, meaning that it then cannot detect small objects. Therefore
it is best to turn your detector off and head outside, as far away as
you can from sources of electromagnetic disturbance.
Sweeping the coil
The Explorer will perform at its best when the coil is kept in close
proximity to the ground. This will increase detection depth and
response to small objects. Becoming practised at sweeping the
coil is very important, as variation in coil height at the end of each
swing can cause confusing sounds and reduce detection depth.
Each sweep of the coil should overlap the last one (Figure 5.2).
This will ensure good ground coverage.
You think you’ve found something?
When an object is detected, the Explorer emits an audio response
and visually displays a target classification on the control panel’s
screen.
Before you attempt to pinpoint or recover the object –
which is explained later in this chapter – it is vital you
understand how to interpret these audio and visual
responses.
This is explained over the next few pages.
Figure 5.2 Sweeping the coil
BEGINNER USE
Audio Overload
Sometimes it is possible that a
large object close to the search
coil will overload the detector’s
electronics. When this happens,
the Explorer emits a low ‘warble’
which will repeat until the coil is
moved away from the source of
the overload.

GETTING STARTED
Introducing Quickstart
Figure 5.1
When you first turn on the Explorer, the Quickstart Smartfind
display will appear and you are able to begin detecting. The
detector is prepared to respond to non-ferrous targets while
filtering out ground signals.
The following pages in this chapter outline the basics of metal
detecting and use of the Explorer. Y ou will learn how to interpret
its responses to targets and make your own adjustments to the
settings.
Regardless of your level of experience with metal detecting,
Minelab recommends you begin in Quickstart mode to familiarize
yourself with basic features and operation before experimenting
with the detector’s advanced features (detailed in Chapter 6:
Advanced Use).
A number of additional functions and features that are likely to be
accessed frequently while detecting are also explained.
These include:
• Target SENSITIVITY and THRESHOLD levels, adjusted with
shift buttons
• IRON MASK and PINPOINT, activated by shortcut buttons.
• MENU functions, accessed from the control panel shift
buttons. These enable you to adjust the display and audio,
define targets and move into Advanced mode.
Figure 5.1 Quickstart’s opening screen
Now that your detector is assembled, batteries inserted and you are familiar with the control
panel, you should be ready to start detecting. This chapter on Quickstart is designed to be
the starting point for all users of the Explorer.
GETTING STARTED

• The horizontal dimension (or axis) rates the extent of the
object’s resemblance to ferrous characteristics.
• The object’s cross-referenced rating is represented by a
‘target crosshair’ inside the rectangular display area.
Interpreting target responses
Conductivity
• Objects with high conductivity (e.g. large silver coins, copper
items) will cause the target crosshair to appear at the top of
the Smartfind screen.
• Objects with low conductivity (e.g. small alloy coins, foil) will
cause the target crosshair to appear at the bottom of the
Smartfind screen.
Along with the type of metal, the size of objects will have some
effect on the conductivity rating for targets. Generally, the larger
the target, the higher the corresponding conductivity rating (and
proximity of the target crosshair to the top of the screen).
Ferrous content
• Objects with high ferrous content cause the target crosshair
to appear on the left of the screen unless its rating would
situate the object in the dark area of the discrimination pattern
(see page 44).
• Objects with low ferrous content (e.g. jewelry, coins) cause
the target crosshair to appear on the right of the screen.
The preset discrimination setting is designed to search for Coins.
NOTE Both ferrous and non-ferrous objects have varying
degrees of inductive response to electromagnetic waves.
This characteristic – in addition to conductivity – allows for
more accurate identification of targets.
QUICKSTART’S SMARTFIND DISPLAY
Discrimination
Discrimination is the ability of a
metal detector to identify the user’s
desired target (e.g. jewelry) and
eliminate signals from unwanted
material (e.g. nails).
The Explorer can be programmed
in a number of ways to discriminate
against unwanted targets in
different types of ground.

will be helpful before Smartfind's Iron Mask and Discrimination
functions are explained in the next few pages.
Two-dimensional discrimination explained
QUICKSTART’S SMARTFINDDISPLAY
When first using the detector, you will see the Smartfind screen. Smartfind displays an
object's characteristics using a two-dimensional scale of target discrimination.
The Explorer rates detected objects according to their conductivity
(like most traditional detectors). What makes two-dimensional
discrimination unique is a rating of the same object's ferrous
content. Smartfind graphically represents both of these target
properties on the same display.
• The vertical dimension (or axis) rates the object on size/

Adjusting the Iron Mask
Figure 5.5
Pressing the IRON MASK shortcut button on the control panel will
display the Iron Mask adjustment screen.
Preset Level
The Explorer's Iron Mask is set at a rating of -6. This is suitable
when detecting non-ferrous metals.
Detecting more ferrous objects
If you want target responses from more ferrous objects (e.g. war
relics) it is necessary to reduce the level of ferrous rejection. This
is done by pressing the bottom left shift button next to the slider
control, reducing the extent of the Iron Mask. You may need to
experiment a little with the settings.
Detecting all ferrous objects
If you wanted to detect all objects, regardless of ferrous content,
ferrous rejection can be reduced to a minimum level of -16. The
screen will be completely clear and all objects will sound a target
response.
Rejecting all ferrous objects
If you want target responses to be suppressed for all ferrous
objects, the Iron Mask may be increased to a level of 0. This is
represented by the mask extending to half way across the
Smartfind screen (as depicted in the section explaining
two-dimensional discrimination, see page 42).
Figure 5.5 Adjusting the Iron Mask
The Iron Mask shortcut button on
the control panel allows you to
switch between Iron Mask and

Before you experiment with this,
an understanding of the features

and how to adjust the Explorer to
suit your preferences.

Introducing Discrim
Discrim (an abbreviation of Discrimination) instructs the detector to
accept some types of targets and reject others. It uses Smartfind's
two-dimensional discrimination, allowing you to specify one or more
target patterns for detection.
Smartfind Discrimination pattern
Figure 5.4
When you begin in Quickstart, you will see a Smartfind display
resembling Figure 5.4. This display shows that the detector is
ready to operate in its preset Coins Discrim function.
The discrimination pattern represents the typical characteristics of
non-ferrous coins (actually a composite of hundreds of coins from
around the world). When the search coil passes over an object
matching the conductive and ferrous characteristics of coins, the
target crosshair will appear in the cleararea and a target response
will sound. Objects outside of the accepted (clear) area are not
displayed and the threshold ‘hum’ is temporarily silenced. The target
crosshair will remain locked in the position of the last accepted target.
The discrimination pattern 'maps' the specific ferrous andconductive
properties of coins, providing excellent accuracy in detection of this
particular type of target.
NOTE Quickstart offers a range of discrimination patterns
which may be used on their own or in combination. This is
detailed in Selecting Targets, page 62.

conductivity and 32 represents a highly conductive target.
To the right of the digital read-out you will see an icon representing
the possible target and, in full screen display, a list displaying up to
three possible target classifications.
Although Digital mode does not display the ferrous content in its
numeric rating, this calculation is used in the identification of the
target and the representative icon. If you wish to revert back to the
Smartfind display, simply press the DETECT button.

Operating in Iron Mask
Figure 5.6
Pressing the IRON MASK shortcut button again will display a
Smartfind screen resembling Figure 5.6. This display shows that the
detector is ready to operate in Iron Mask. This function is
programmed to reject ferrous targets and make it easier for you to
find more desirable (non-ferrous) objects like coins and jewelry.
Iron Mask is preset to reject ferrous objects at a level suitable for
basic detecting. This is shown in Figure 5.5 as a rating of -6 with
the dark area filling the left third of the screen. Smartfind will not
display an object when its target crosshair would appear in this
dark, masked area of the screen and the Explorer’s threshold
‘hum’ will disappear momentarily.
However, if you wish to locate specific types of objects you may

ADJUSTING SENSITIVITY
Sensitivity control
The sensitivity bar indicates how responsive the detector is to a
target in the presence of ground noise and/or electromagnetic
interference.
The degree of sensitivity is increased by pressing the top shift
button and decreased by pressing the bottom shift button (on the
left side of the control panel). Pressing the center left shift button
switches between semi-autoand manual sensitivity.
Semi-auto
A line cycling around the number indicates that the detector’s
sensitivity is in semi-automaticmode. In this mode, the detector
continuously monitors the environmental conditions and will adjust
actual detector sensitivity as close as possible to your specified
level of stability, depending on these conditions.
Manual
In the manual mode (where the line does not cycle around the
number) the adjustment controls the sensitivity directly. This mode
is suitable for the beach and very quiet (unmineralized) ground.
Manual sensitivity is also recommended for high trash areas when
best results are obtained by sweeping the coil very slowly.
A high manual number is preferable for stable conditions with low
interference. A low number is suggested for very variable, ‘noisy’
conditions.
Adjusting sensitivity
The highest sensitivity setting (32) is suitable in only the least
‘noisy’, most stable environments. Decreasing sensitivity will
stabilize the detector where it is affected by noise or interference,
but will marginally affect depth penetration and detection of small
objects. This may still be preferable to operating with excessive
background ‘chatter’.
ADJUSTING SENSITIVITY
So that you can detect in best
conditions, we would advise you to
always choose the channel with
least interference before beginning
your detecting session.
If the detector becomes noisy and
you suspect electromagnetic
interference, change to a better
channel before adjusting
sensitivity.
To do this automatically, press the
Noise Cancel shortcut button
(Explorer XS), or manually select
the least noisy channel
(Explorer S or XS, see page 83).

AUDIO RESPONSE
Pitch of response
Figure 5.13
Generally, a target that is highly conductive (e.g. a large silver
coin) emits a high pitched signal. A low pitch is sounded for less
conductive targets. Large targets or targets close to the ground
surface emit a louder signal.
In Quickstart’s preset function, Coins Discrimination, the target
audio response is emitted if a target is predominantly non-ferrous –
when the target crosshair is displayed in the clear part of the
Smartfind screen (Figure 5.13).
As you detect different targets you will quickly find it easy to
identify objects by the audio and visual responses of the
Explorer. Directions for familiarizing yourself with specific target
responses appear toward the end of this chapter.
Adjusting the volume
The preset volume control on the Explorer is turned up to
maximum volume. This is usually appropriate with either the
detector’s built-in speaker or headphones. If the volume is too loud
in the headphones, use the volume control.
Main Menu > Audio > Volume > Max. Limit can be set to reduce
potentially loud signals (see page 54).
The Explorer emits a target audio response that varies in pitch and volume depending on
what type of object it detects.

Threshold control
The Explorer usually emits a constant tone or threshold ‘hum’ in
the absence of a target. The threshold setting controls the audible
level of this sound during detecting. Minelab recommends setting
the threshold to a comfortable audible level in the early stages of
your detecting session, as this feature is designed to highlight the
variations in signal response which often indicate detection of a
target.
Threshold level is increased by pressing the top shift button and
decreased by pressing the bottom shift button (on the right side of
the control panel). A number corresponding to the threshold level
will appear temporarily between the two adjustment arrows.
Preset threshold
The preset level of 10 will usually emit a constant threshold hum.
This level is programmed to enable audible response to most target
signals.
Suggested threshold setting
Everyone’s hearing is different, so Minelab suggests that your
preferred level of threshold be set to a very low, but still audible
level. The threshold setting may need to be adjusted when moving
from speaker to headphones.
Reducing threshold
With the level set at 5, there will usually be no constant threshold
hum. Adjusting the level to 0 will ensure silent operation but could
mask audio response to small targets.
Increasing threshold
The threshold hum will become louder as the threshold level is
increased. Small target responses will become difficult to discern
as threshold nears a maximum setting of 20 when there is certain
to be a persistently loud threshold hum.

Max limit
Main Menu > Audio > Volume > MAX LIMIT (adjustment)
This setting is the detector’s overriding volume control. It controls
the ‘loudness’ of a signal response emitted from the detector,
much like the volume knob on a stereo system.
A setting of 0 instructs the detector to be completely silent.
A setting of 10 instructs the detector’s audio to operate at its
maximum level of ‘loudness’.
Lower settings are likely to help extend battery usage time.

AUDIO MENU
Introduction to the Audio menu
Figure 5.14
Main Menu > AUDIO
As mentioned earlier in the section on Audio Response, the
Explorer emits a target signal that varies in volume and pitch
depending on the object it detects. Generally, large targets or
targets close to the ground surface emit the loudest signal.
A target that is less conductive emits a low pitched signal and a
highly-conductive target emits a high pitched signal.
The AUDIOmenu allows you to modify the detector’s operating
VOLUME, TONE and define the SOUNDS emitted to lend greater
refinement to audio responses.
Figure 5.14 The Audio menu
Features accessed through the Audio menu allow you to define the various audio
properties of your Explorer.
AUDIO MENU
Headphones
Use of the Explorer with
headphones will allow you to
discern subtle variations in audio
response and lessen exposure to
adverse conditions (i.e. wind)
which may distort sound from the
speaker. Headphones also
minimize disturbance from your
treasure hunting for other people
in the area.

AUDIO: ADJUSTING THE TONE
Introducing Tone
Figure 5.18
Main Menu > Audio > TONE
Tone is the frequency of sound emitted on target detection. It is
important to experiment with tone settings and listen carefully to
tone variations during your detecting. To test variation in tones
upon selection it will be helpful to move the coil across a few
different targets spaced apart.
Threshold tone
Threshold Tone allows you to adjust the tone of the threshold
‘hum’. This can be modified using the slider control to suit your
preferred threshold tone.
Variability
Variability controls how much the tone will change depending on
the target’s characteristics. A setting of 10 represents significant
variation from target to target. A setting of 1 represents minimum
change in pitch. Variation of pitch between targets can greatly
assist in identifying targets in close proximity to one another.
Limits
This sets the upper limit of all tones emitted by the Explorer.
Minelab recommends setting the upper limit to the highest
frequency you are comfortable with. You can test the upper limits
with a highly conductive object (e.g. a large silver coin). Setting
the limit to 1 will produce only low pitch target signals, a setting of
10 will provide very high as well as low pitch signals.

AUDIO: ADJUSTING THE VOLUME
Gain
Figure 5.16, 5.17
Main Menu > Audio > Volume > GAIN (adjustment)
Volume gain affects the way the detector amplifies target audio
responses in respect to the strength of the original signal.
Looking at figure 5.16, it is clear that with a setting of 1 the sound
produced will be proportional to the strength of the signal for the
whole range of signals. Based on this and the depth indication,
some information on the size of the target can be inferred. It
should be noted that in this case weak signals will produce an
accordingly faint audio signal.
With the preset value of 5, the audio response is being partially
amplified. Weak to medium strength signals will give proportional
responses, but strong signals will not sound much louder than
medium ones because the sound has reached its maximum limit
(Figure 5.17).
On the other hand, with a setting of 10, all but the weakest signals
will be amplified to a very strong audio response (Figure 5.16). No
indication of size or strength of target signal can be deduced in this
case, but even weak target signals will be easier to hear.

AUDIO: ADJUSTING THE SOUNDS
Ferrous
Main Menu > Audio > Sounds > FERROUS
Selecting FERROUS adjusts the tone according to the target’s
ferrous content (the horizontalaxis of the Smartfind screen). A low
‘blaat’ tone denotes a highly ferrous object, displayed on the left of
the screen. A high pitched ‘squeak’ tone denotes a non-ferrous
target, displayed on the right of the Smartfind screen.
Clear the Smartfind screen to test the Ferrous sound. There are two
ways to do this: adjust the Iron Mask level to -16 or choose CLEAR
from Main Menu > Discrim > SELECT.
NOTE When the Iron Mask is set to the left of the Smartfind

pitch between detected objects. When the Iron Mask is fully
activated (setting 0) there will be no signal for objects with
ferrous content.

The SOUNDS menu allows you to define how the pitch varies with
target characteristics. This can be a very useful feature in identifying
targets in close proximity to one another. It is possible to instruct the
detector to emit a distinct sound responding to an object’s ferrous
characteristics, rather than its conductive properties. To test sounds
upon selection it is necessary to move the coil across one or more
targets with different conductive and ferrous properties.
Constant
Main Menu > Audio > Sounds > CONST
Selecting CONST eliminates the variation of the pitch upon detection.
If selected, the Explorer will emit a consistent tone regardless of the
target detected.
Conductivity
Main Menu > Audio > Sounds > CONDUCT
Conduct is the factory preset and Minelab’s recommended option.
Selecting CONDUCT adjusts the tone to identify the object relative to
its conductivity (the verticalaxis of the Smartfind screen).
A high pitched tone denotes a large, highly conductive object with
target crosshair displayed near the top of the Smartfind screen
(or near a Digital rating of 32).
A low pitched tone denotes a small object with low conductivity. The
target crosshair is displayed near the bottom of the Smartfind screen
(or near a Digital rating of 1).

PINPOINTING THE OBJECT
Introducing Pinpoint
Figure 5.20. See also Pinpoint overview in Chapter 4: Control Panel, page
34.
During normal operation the Explorer operates with discrimination
settings like Iron Mask or targets chosen from the Select target list.
When the approximate location of a target has been determined, it is
necessary to identify the object’s exact position. This is done using
the Explorer’s Pinpoint function.
Enabling Pinpoint instructs the Explorer to temporarily disengage
discrimination and become an ‘all metal’ detector. This means that
objects normally discriminated against will emit a target signal when
beneath the coil.
For example, Iron Mask is activated and the Explorer has detected
the approximate location of a non-ferrous coin but ignored the rusty
nail buried nearby. Selection of Pinpoint instructs the Explorer to
respond to all metals positioned directly beneath the coil. Now,
instead of a single signal for the coin the detector will also respond to
the nail.
It should be noted that the Pinpoint function is designed to zone in on
a target with subsequent passes. For this reason it is recommended
that you maintain the same sweep height above the target and not to
pass repeatedly back and forth across the target at various heights.
This incorrect method can cause the detector to desensitize and
reduces the depth of Pinpoint. If this happens, remove the coil from
the area of the target for a few seconds so its sensitivity can recover.
For this reason, Minelab recommends Pinpoint is only used
once the approximate location of a target has been
determined. The display screen’s Pinpoint indicator will flash to
remind you to turn Pinpoint off before resuming normal detecting.
Instructions for the use of Pinpoint appear on the following page.

Take some time to become familiar with how the Explorer
responds to various metal objects. This tutorial is
designed for Smartfind’s Iron Mask and Discrimination
functions. Repeat the procedure to familiarize yourself
with both.
Gather a collection of different metal objects like a rusted nail,
pull-tab, brass button, aluminium foil, various coins, and some
gold and silver jewelry. Take the detector outside, away from
known electromagnetic devices or metal objects.
STEP 1 Find an area of ground without targets.
STEP 2 Lay objects in a line, sufficiently spaced apart to allow
the coil to pass between the objects.
STEP 3 One at a time, pass the coil across the test objects. The
detector should ‘beep’ on the non-ferrous objects and
ignore the ferrous objects.
STEP 4 Take note that as the coil is passed over the nail, the
threshold ‘hum’ disappears, indicating that the object
ignored was ferrous.
STEP 5 Passing the coil over different non-ferrous objects will
produce different signal tones. Objects with high
conductivity, such as silver or lead, produce a highpitched signal tone while objects with lower conductivity,
such as aluminium foil, produce a lower pitched signal
tone.
With experience (and adjustments to the Audio settings) it will
be possible to use the signal tone from an object to accurately
determine the type of object discovered before recovering it
from the ground.

RECOVERING THE OBJECT
For this procedure you’ll need: a knife or trowel, a small
spade and a sheet of plastic.
STEP 1 Once the object has been pinpointed, clear the surface of
loose material and check again for the signal. If there is no
signal then the object is amongst the surface material. In this
case, search the surface material until the object is located.
STEP 2 If the object is still in the ground, check again using Pinpoint.
If you are about to dig in a grassy area, first remove a plug of
grass using a sharp knife or trowel.
STEP 3 Dig carefully to avoid defacing or devaluing the object. The
use of probes can often aid in locating the exact position of
the object prior to digging.
STEP 4 Place the grass plug and all soil you dig onto a plastic sheet
beside the hole. This sheet (which can be folded small
enough to fit into your pocket) enables you to keep all soil
for refilling the hole and prevents material being scattered
about the area.
STEP 5 Check the hole for the object. If it is not in the hole, place
the detector on the ground and with the coil flat, pick up dirt
by the handful and pass over the coil. Be sure you are not
wearing any metal objects like rings, bracelets or a watch
which may interfere with the signal. If you receive no
response, return the dirt to the hole. Repeat this procedure
until the object is located.
STEP 6 Check the hole again with the detector. Ensure that no other
objects remain, then refill the hole. All soil on the plastic
sheet should be returned to the hole followed by the plug of
grass. This should leave the area as you found it.
Fill your holes!
For the safety of others and in the
interests of respecting the
environment, ensure you leave an
area of ground as you found it.
Leaving holes, or an area ‘scarred’
may result in action being taken to
prevent the use of metal detectors
(which spoils the hobby for others
as well as yourself!)

STEP 1 Move the search coil to one side of the approximate target
location and press the PINPOINT shortcut button. If this
step is not taken the Explorer will sound when moved away
from the object.
STEP 2 Slowly sweep the search coil over the target a couple of
times. You will only hear a sound when the center-bar of the
coil is directly in line with the target.
STEP 3 Taking note of the detector response, reduce the span of
each successive pass of the coil until you are confident of
the target’s location. Make a mental note of the position.
STEP 4 Move to one side so that you can pass the coil over the
target at a right angle to your initial direction.
STEP 5 When the detector sounds you should know exactly where
to dig.
STEP 6 If you have difficulty pinpointing the target, press the

following pages show you how to instruct the detector to ‘learn’ a particular target and
save its characteristics for later use.
Figure 6.1 The Learn screen
Introducing Learn
Figure 6.1
Sometimes during your treasure hunting you may wish to instruct
the Explorer to detect targets with very specific characteristics.
It may be that you have found a particular type of coin which you
would like to find more of, or you find yourself constantly
unearthing the same types of junk.
Minelab has designed Learn to enable you to instruct the Explorer
to accept or reject precisely the types of targets you do or do not
want.
Your new target patterns are treated in exactly the same way as
those you have used from the SELECT target list. Once saved,
they can be used by themselves or in combination with other
discrimination patterns.
In time, you may find this one of the Explorer’s most powerful
features. For instance, once you have saved target patterns of
several unwanted targets you may exclude them all from your
current Smartfind discrimination pattern simply by rejecting them
from the SELECT target list. In a similar way, you could combine all
of your desired targets into your own composite discrimination
pattern.
The following tutorial will help you to make Learn a feature of your
metal detecting.
NOTE Selection of Pinpoint effectively disengages the
Explorer’s Discrimination functions.
Silence please!
For the Learn option to work
accurately, it needs to recognize
the same target characteristics
with each pass of the search coil.
For this reason, it is essential that
you use Learn in an environment
free of electromagnetic
disturbance. This may mean
moving away from other
detectorists or powerlines.
It may be useful to perform a
Noise Cancel before undergoing
the procedure outlined in the
following tutorial.

Phase 2: Learning and Saving the target pattern
STEP 7 Wave the search coil several times above the desired
target until the detector learns it by clearing an area on
the screen. Learn needs to ‘see’ the target consistently to
accept it for inclusion. If you have more than one target,
repeat the procedure for each one. In Figure 6.5, two
current high denomination coins have been used.
STEP 8 When you have finished learning the targets, press the
shift button next to the flashing tick.
STEP 9 Press the shift button next to the Save icon to go directly
to the SAVE DISCRIM menu. Press a button next to your
choice of option S1–S6 (for example S1 in Figure 6.6).
This will save the learnt discrimination pattern for future
use.
STEP 10 Press the DETECT shortcut button to return to the

As described earlier in this chapter, Advanced mode’s LEARN
display allows you to accept or reject a target and create your own
discrimination patterns.
EDIT offers a final enhancement to these targeting features,
enabling you to make manual changes to any discrimination
pattern.
For example: Learn mode’s target selection may not provide quite
the result you wanted (even when using a different-sized cursor)
Rather than start all over again, you can just ‘touch up’ your
results. Similarly, you may find that the discrimination pattern for
FOIL may need to be modified to suit your requirements.
The following tutorial outlines how to edit and then save
discrimination patterns.

Noise
Figure 6.18
Main Menu > Options > NOISE
Sometimes during detecting you may notice some interference in
the form of erratic noises and movements of the target crosshair
(even without movement of the detector). The NOISE option
enables you to select an operating channel which does not clash
with other detectors or electrical sources in the area. This feature
is also good for metal detecting competitions if several Explorers
are working close to one another. Each detector can be set to
operate on a different channel so interference between detectors
is eliminated.
The factory setting for NOISE is 5.
NOTE It may be useful to select manual sensitivity from
the Smartfind or Digital screen before attempting this
procedure. Sensitivity is covered in Chapter 5: Quickstart,
page 49.
To adjust channel for least noise:
STEP 1 Rest detector on the ground. Make sure the detector is not
moved and the area is clear of targets.
STEP 2 Use the shift buttons next to the adjust arrows to select a
channel and listen for interference (or ‘noise’). Adjust the
detector to a new channel and listen again. Do this with
each channel in turn until you locate the channel with the
least noise.
NOTE The number associated with Noise does not denote
an increase or decrease in power. It is simply a channel
number which can be remembered.

Audio 2
This setting is similar to Audio 1, with the addition of some filtering
of the audio tone response. Audio 2 reduces the variability of the
pitch, offering a smoother continuous sound.
Audio 3
This setting is similar to Audio 2, with increased filtering of the
audio tone response. This offers more consistent tone for a single
target, but for multiple targets the tones will ‘blend’.
NOTE It is recommended you experiment with these settings
once you are familiar with the sounds produced by the
Explorer in the Normal Response setting, then choose
according to conditions and preference.

Introducing Response
Figure 6.19
Main Menu > Options > RESPONSE
The relationship between proximity of targets to one another and
detector response can influence its performance. The RESPONSE
option allows you to select the way the detector responds to
targets and change the way targets sound upon detection.
Response can affect your ability to identify certain targets in
differing circumstances.
Normal
This is the factory preset of the detector in Quickstart and
Advanced modes. Only Advanced mode provides alternative audio
options to Normal. Normal emits a short response to targets
(almost a 'beep') and is recommended for general detecting
conditions. However, it should be noted that Normal has the
potential to miss small targets in areas littered with objects
producing a target response.
Audio 1
This setting is ideal for responding to several targets close
together. Audio 1 offers an almost continuous audio response.
It is recommended for the experienced user who can pick the
differences in tone between various targets. This setting should be
used in combination with display responses. It will help if you
sweep the search coil in different directions to separate the
targets. The tone can be more confusing for the beginner, but it
has the potential to offer greater accuracy and depth.

Once you have selected and modified the detector’s operational
settings (as detailed in Chapters 5 and 6) it is possible to save
them to the Explorer’s memory for future detecting sessions.
Advanced mode allows you to save and load two different settings
(in addition to the factory presets). It may be that two people with
different preferences use the detector (e.g. different volume, tone,
sensitivity settings) or perhaps you divide your time between a
couple of very different detecting environments (e.g. the beach and
a highly-mineralized battlefield). The Explorer’s Settings feature
makes it easy to save rather than going through the whole finetuning process again.
Saving and loading a setting
For example, to saveyour current detector settings, press the shift
button next to USER A or USER B on the right side of the screen. A
screen prompt will appear asking if you want to save current
settings in the memory. Select YES.
You can now proceed to detect with this setting knowing it has been
saved for future use in similar conditions. On the next occasion you
wish to use these preferred settings you can load by choosing
SETTINGS from the Options menu and pressing the shift button next
to the USER A or USER B option on the left side of the screen.

Make sure that you start with the Main Menu > Audio > Sounds >
CONDUCT selected and the threshold level and the volume are
appropriate for your environment (i.e. for headphones or speaker
use, ambient noise etc.)
STEP 1 Adjust the threshold 'hum' to a tone you are comfortable with
using the Main Menu > Audio > Tone > TH. TONE. This
tone should be the lowest tone you can still hear clearly.
STEP 2 Using two targets you are likely to often seek which display a
difference of 1 or 2 on the digital reading, adjust Main Menu
> Audio > Tone > Variability so you can hear the difference
between one and the other.
STEP 3 Select a target with high conductivity (giving a high number
on the digital display) and wave it past the coil. Adjust Main
Menu > Audio > Tone > Limits for a pitch as high as
possible but still within the range where you can hear well.
If you want the detector to reject targets (for example to make a
new pattern for bottle caps, suitable for your conditions):
STEP 1 Prepare a number of targets from the category you want to
reject (bottle caps).
STEP 2 Go to Advanced Learn and start with an all black screen.
STEP 3 Select Learn Accept (the flashing tick) and pass the coil
over the bottle caps until the detector accepts them.
STEP 4 Go to SAVE (press the shift button next to the SAVE icon)
and save to the location you want (e.g. S4). The Smartfind
thumbnail will display your pattern.
Now that this pattern has been saved, you can use it to construct
your own discrimination pattern by:
• Going to SELECT menu and choosing CLEAR. For instance,
construct this personal discrimination pattern by accepting
coins with a tick and rejecting your newly learnt bottlecaps
pattern (S4) with a cross.
• If you want to improve the pattern, use Advanced Edit to
modify the clear (accepted) area.

user tips
It is normal for the tip of the rechargeable battery to get warm while
charging because the current regulator is mounted inside the
battery pack.
Using headphones extends battery life. The speaker draws
significant current from the battery for short amounts of time. Using
the headphones when the battery voltage is low (when the battery
indicator’s level starts decreasing) helps in getting the most out of
the battery.
It is best if you perform a Noise Cancel with the search coil in the
position used for detection. This is because the interference picked
up in a vertical position can be different from the interference
picked up in the horizontal orientation.
In competitions, where several Explorers have to work nearby, it
might be best to select the channels manually.
If you want to know what channel has been chosen by the detector
after a Noise Cancel, go into the Advanced mode in Main Menu >
Options > NOISE and look at the number displayed. If you do a
Noise Cancel while in that menu, you have to go out of the menu
and back to get the new channel number.
If you want to clear one or more patterns from the SAVE DISCRIM
menu, do the following:
STEP 1 Go to SELECT menu and select CLEAR.
STEP 2 Go to the SAVE menu and save cleared screen into the
locations you want.

Discrimination pattern A two-dimensional pattern made up of shaded and clear regions of
the Smartfind screen. Characteristics of a target are used to
determine its position on a two-dimensional display. A discrimination
pattern is typically a target pattern modified by the user to accept or
reject certain objects through the use of combined targets from the
SELECT menu or created in Advanced mode’s LEARN or EDIT
displays.
Edit One of Explorer’s Advanced displays. Edit allows the user to
customize an existing discrimination pattern to match preferred target
characteristics.
Ferrous Composed of or containing iron. A ferrous object is one that is
predominantly or completely iron. Ferrous objects (e.g. nails) are
usually not desired by the detectorist.
Full Band Spectrum (FBS) Simultaneous 28 frequency transmission ranging from 1.5kHz to
100 kHz. This range in frequencies means that the signal received
from the detector coil is analyzed from a wide range of responses.
Full screen Target details shown on the full screen with display border and the
other screen elements removed. An icon at the center right of
screen switches to full screen display.
Ground compensation The ability of the detector to compensate for the effects of ground
mineralization.
Handle assembly Part of the detector made up of the control box, handle and armrest.
Inductance The electrical property of a metal target to oppose variations of the
magnetic field. This characteristic is referred to as ferrous content
in Smartfind.

Advanced mode The Explorer’s advanced operating mode. Advanced mode
provides additional features and options to Quickstart.
Alloy A substance which is composed of two or more metals
(an alloy may also include non-metals).
Camlock Lever which releases or locks detector’s assembly components. The
Explorer’s upper and lower shafts are connected by the shaft
camlock. This shaft assembly is connected to the control box by the
control box camlock.
Conductivity A measure of the ability of a target to allow eddy currents induced by
the transmitter.
Control box Encloses the electronic components necessary to generate and
interpret signals transmitted from the search coil and provide user
access to functions via the control panel.
Control panel This panel, which sits on top of the control box, houses the display
screen and provides press-button access to all of the detector’s
operating functions.
Digital One of Explorer’s displays. Digital rates an object’s conductivity as
a figure between 1 and 32. Digital also displays an icon
representing the possible target.
Discrimination The ability of a metal detector to identify the user’s desired target
and eliminate signals from undesirable material. The Explorer can
be programmed to discriminate against unwanted targets in either
Iron Mask or Discrim.

Sensitivity The detector’s level of response to a target in the presence of
ground noise and/or electromagnetic disturbance.
Shaft assembly An adjustable assembly made up of the upper and lower shaft
connected by camlocks. The shaft assembly connects the search coil
to the handle assembly.
Shift buttons The three buttons at either side of the display screen are called shift
buttons. They allow selection of adjacent menu items, movement of
screen slider controls and adjustment of settings.
Shortcut buttons Blue buttons on the control panel which offer quick access to the
functions and settings most likely to be used during detector
operation. Noise Cancel, Iron Mask, Pinpoint and Detect are all
shortcut buttons.
Slider control Visual representation of setting adjustments for a particular function
(e.g. screen contrast). Settings may be adjusted with shift buttons at
either side of the display screen.
Smartfind One of the Explorer’s displays. Smartfind visually represents target
details using two-dimensional discrimination.
Threshold (hum) The audible level of sound emitted when no target is detected is
the threshold. This threshold hum is the background sound made
as the Explorer operates. Threshold can be set anywhere between
no sound (silent) and loud.

Iron Mask One of the Explorer’s Smartfind displays. The Iron Mask function
rejects objects with ferrous properties. This level of ferrous rejection
is represented with a dark ‘curtain’ which moves across the
horizontal dimension of the Smartfind screen as the Iron Mask is
adjusted.
Learn One of Explorer’s Advanced displays. Learn allows the user to
accept or reject certain targets to create a personalized
discrimination pattern.
Mineralized ground Ground containing certain minerals which can cause false signals to
be given. Mineralized ground is handled automatically by the
Explorer’s ground compensation.
Nickel Metal Hydride (NiMH) Nickel Metal Hydride batteries are the modern equivalent of older
NiCad (Nickel Cadmium) batteries. NiMH batteries have a longer
life-span and are not affected by memory to the same degree.
Non-ferrous Not containing iron. Non-ferrous objects or non-magnetic metals
(such as silver or copper coins, gold jewelry, etc).
Pinpoint Function allowing an object to be precisely located. Pinpoint
overrides the automatic motion detection and discrimination settings
of the Explorer.
Quickstart mode The Explorer’s basic operating mode.
Recovery Recovery, one of the Explorer’s Advanced options, allows the user
to modify the way the discrimination process works and affects the
audio and display responses to target characteristics.
Response The signal or audible indication of a target. Also a menu affecting the
audio response of the detector.
Search coil The search coil is the circular plate swept across the ground surface
during detecting. It transmits electromagnetic signals into the ground
and receives the response.

take care
The Explorer is a high-quality electronic instrument, finely engineered and
packaged in a durable housing. Taking proper care of the detector is mostly
common sense.
• Do not leave the battery pack in the Explorer handle when the detector is not in use for
extended periods of time. Damage caused by leaking batteries could be severe and would void
the warranty through user negligence.
• If temperatures are very high, do not leave the detector in excessive heat for longer than
necessary. Covering it when not in use will help protect it. Try to avoid leaving it in a closed
trunk or in a car sitting in sunlight.
• The control box has been designed to resist moisture. However, Minelab advises protecting the
control box in extreme conditions. Obviously the control box should not be dropped into water.
• Never allow the detector to come into contact with gasoline or other petroleum-based
liquids.
• Keep the detector clean and dry and avoid getting sand and grit into the shafts or fastenings
(e.g. yoke bolt and camlocks). Do not use solvents to clean the detector. Use a damp cloth with mild
soap detergent.
• Ensure the coil cable is in good condition and not subject to undue stress.
• Search coil. The Explorer coil is not interchangeable with any previous Minelab model.
• Flat or faulty batteries cause many detector problems. Ensure that only quality alkaline
batteries are used, and that they are replaced when you hear the warning signal through the
headphones or speaker.
• Do not dispose of battery pack in fire (contact local authorities for disposal/recycling).
Do not attempt to disassemble or short circuit the battery pack.
• Take precautions when transporting or storing the detector. Although the detector is
constructed from the highest quality materials and has undergone rigorous durability tests, the
display screen could be prone to scratching or serious damage if not treated with due care.
