Metal detectors create an electromagnetic
(EM) field around the coil, which penetrates
the ground. Because metal is conductive it
causes a change in this field. The detector
senses this change through the coil and
sends a signal back to the control box,
alerting the operator.
Metal detectors can determine the size, shape
and composition of metallic objects beneath
the coil. Typically, the larger the object, the
easier it is to detect.
A metal detector’s EM operating frequencies
are measured in kiloher tz (kHz). Low
frequency EM fields (e.g. 1.5kH z) penetrate
the ground deeply, but sensitivit y to smaller
targets is low. High frequency EM fields (e.g.
65kHz) have a shallower depth of penetration,
but sensitivity to small targets is high.
E-Trac’s multiple frequency operation provides
the advantage of both; good depth and
high sensitivit y.
How Metal Detectors Work The Technology of E-Trac
Full Band Spectrum (FBS)
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 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 effectively a
detector transmitting a single frequency
would operate.
FBS technology combines Minelab’s
multiple frequency BBS (Broad Band
Spectrum) technology with a powerful new
microprocessor to give:
• Greaterdetecting depth
• Highsensitivity overawide range
of targets
• Lessinterferencefromelectromagnetic
sources
• More accurate identication of target
characteristics
The FBS circuit automatically transmits
multiple frequencies simultaneously. This
increased frequency range means that the
signal received from the detector coil is
analysed from a wide range of responses.
This allows E-Trac to analyse more target
information so that the target identification
(ID) is more accurate.
Minelab’s unique FBS technology means
deep, sensitive, accurate detecting.
Discrimination (Disc.)
Discrimination is the ability of a metal
detector to identify your desired targets (e.g.
coins and jeweller y) and eliminate signals
from undesirable material (e.g. nails).
E-Trac can be programmed in a number
of ways to discriminate against unwanted
targets in different types of ground.
Ground Compensation
E-Trac uses a sophisticated approach to the
elimination of ground mineralisation. I t uses
advanced digital filtering to eliminate the
influence of ground signals. This is achieved
automatically, allowing you to concentrate on
detecting targets.

New Features
Liquid Crystal Display (LCD)
E-Trac’s LCD has a viewing area of 72mm x
48mm and improved resolution compared
to previous Explorer models. This provides
clearer on-screen graphics and improved
target identification, making detec ting with
E-Trac much easier.
Ergonomic Keypad Layout
The new keypad layout provides ergonomic,
single-handed access to all of E-Trac’s
functions and settings.
Ergonomic Handle Assembly
E-Trac’s new handle design gives you a
precisely balanced detector with a feel that
is distinctly different and unique to E-Trac.
This allows for excellent manoeuvrability with
firm control on both rapid and slow sweep
speeds and provides optimum comfort over
extended detecting periods. This also ensures
easy viewing of the LCD and access to the
keypad, allowing for quick assessment and
adjustment of settings.
New Menu
In combination with the new K eypad Layout,
the new Menu improves access to settings,
User Modes and Discrimination Patterns,
allowing quick and simple adjustments.
Auto Latch ( Semi-Automatic
Discrimination Editing)
E-Trac now has an Auto Latch feature which
provides semi-automatic editing of your
Discrimination Pattern. In this editing mode,
the Edit Frame will automatically move
to the Ferrous (FE) and Conductivit y (CO)
coordinates of the detected target. You can
then choose to accept or reject that target
from your Discrimination Pattern using the
Accept/Reject button.
QuickMask
QuickMask allows you to adjust the
Ferrous and Conductivity rejection levels
independently of the current Discrimination
Pattern, allowing a fast and simple way of
editing Patterns.
User Modes
A selection of preset User Modes allows
you to choose the best detector settings
and discrimination patterns for the ground
conditions. There are four pre-programmed
Minelab User Modes for you to choose
from, as well as slots for saving your own
personalised User M odes. All User Modes are
easily accessed via the Menu, allowing you to
quickly switch User Modes when required.
Suggested Sensitivity
When using Auto Sensitivity the E-Trac will
show your sensitivit y selection as well as the
‘suggested’ sensitivity, as determined by the
detector, relative to ground conditions.
E-Trac Xchange
E-Trac Xchange allows you to download and
upload detector settings and Discrimination
Patterns via USB. This advanced feature
is designed to allow you to quickly
configure the E-Trac to particular detecting
environments and preferred targets.

Adjusting the Detector for
Comfortable Detecting
For comfortable detecting it is important to
take the time to adjust the detector correctly.
Holding the Detector
Thread your arm through the armrest and
strap. Grasp the handle of the detector and
rest your forearm in the armrest.
The correct position of the armrest should
allow you to comfortably grip the handle.
Your elbow should sit just above the back of
the armrest and the detector should feel like
an extension of your forearm.
Adjusting the Armrest Strap:
1 Loosen the strap by tilting the top edge
of the buckle out to release it from
the armrest.
2 Undo the Velcro and pull the buckle
outwards (towards yourself ) to loosen
the strap.
3 Clip the buckle back into place and tighten
the strap until your arm is secure whilst in
the armrest. Re-attach the Velcro.
2 While holding the detector, slide the
armrest to sit just below your elbow.
3 Remove your arm. Tighten screw (turn
clockwise) to lock the armrest into position.
Adjusting the Position of the Armrest:
1 Use a screwdriver, or the edge of a coin,
to loosen the screw in the centre of the
armrest (turn counter-clockwise).
Adjusting the Length of the Shafts
A correct shaft length will allow you to
swing the coil over the ground without
uncomfortably stretching or stooping.
If the coil is too far from your body it will be
difficult to balance and manoeuvre
while detecting.
If the coil is too close to your body it may
detect your digging tools or any other
metal which you are carrying, causing
confusing sounds.
Adjust the lower shaft to the correct length,
securing the camlock to hold it in place.
A longer lower shaft is available for
tall people (p. 88).
Shaft is the
correct length
Shaft is too short

13
Adjusting the Angle of the Coil:
1 Loosen the bolt that connects the Lower
Shaft to the Coil. It should be loose
enough to allow the Coil to be moved for
adjustment, but tight enough that the Coil
can hold its position.
2 While holding the detector as if detecting,
lightly press the Coil to the ground until it
sits flat/parallel with the ground. The Coil
should remain parallel when lifting to the
sweep height, approximately 25mm (1”)
above the ground.
3 Tighten the bolt, but do not over-tighten it.
E-Trac is supplied with two t ypes of
battery pack.
One is a sealed rechargeable Nickel-Metal
Hydride (NiMH) battery pack. This comes with
a charger which plugs into a conventional
wall socket. The NiMH battery pack is
supplied discharged and needs to be charged
for 18 hours before operating the detector.
The other battery pack is a housing for eight
‘AA’ cell alkaline batteries.

Turning the Detector On
The Power button turns the detector On and
Off. Press the Power button once to turn
the detector On. The detector will begin its
startup with an animation and tune, after
which the Pattern Screen will appear and
E-Trac is ready to find treasure!
It is best to operate the detector only
when outdoors and away from sources of
electromagnetic interference (EMI) such as
power lines and phone towers. These
sources may cause the detector to perform
erratically, giving false signals and causing
inaccurate target ID.
There are also many metallic objects inside a
house, such as nails in the floor, reinforcing
in the walls, televisions and other household
appliances, that might overload the
electronics of the detector.
Reset
E-Trac is Factory Preset to allow you to start
detecting straight away. E-Trac’s Factory
Presets will respond to some low ferrous
metal targets such as silver coins and
jewellery, and ignore high ferrous targets
such as nails.
Any changes made to E-Trac’s settings are
saved automatically while detecting. These
settings will remain until they are changed, or
you instruct the detector to Reset to Factor y
Presets, or Master Reset (p. 79).
When E-Trac is off, press and hold the Power
button for three seconds to turn the detector
on and ‘Reset’ it. Upon ‘Reset’, E-Trac loads
the Factory Preset User Mode and resets the
Universal Settings (p. 38).
User Modes and User Discrimination patterns
are not erased when the detector is ‘Reset’. All
settings within the Preferences Menu are only
reset if you use Master Reset (p. 79).
To Reset the detector:
1 While the detector is switched Off,
press and hold the Power button for
three seconds.
A ‘Reset’ message will appear on the screen
and a tune will sound. After the startup is
complete the detector will be reset and
E-Trac is ready to detect again.
Note: Sometimes it is possible that a large
object close to the coil will over load the
detector ’s elect ronics. When this hap pens,
E-Trac displays an Over load message and
emits a fading Overload sound which repeats
until the coil is moved away from the source of
the overload.
Each time you turn the detector On, the
last Detection Screen used before shutting
down will appear, e.g. if E-Trac was operating
in the Digital Screen when turned Off, then
the Digital Screen will appear when E-Trac is
turned back On.
To turn the detector O ff, press the
Power button.
CAUTION: After turning E-Trac Off, allow
at least 1 second before turning E-Trac
back On. This will allow the detector to
save user settings into the memory so
they are not lost when the batteries
are removed.
Overloading is not harmful to the electronics
of the detector. E-Trac is designed to
withstand coil overload.
20
21
Discrimination
Discrimination is the detector ’s ability to
eliminate signals from undesired targets and
accept signals from desired targets. E-Trac’s
advanced signal processing rates detected
objects according to their conductivity and
ferrous characteristics. This enables you to
accept some types of targets and reject
others; the combination of these accepted
and rejected targets form a Smartfind
Discrimination Pattern.
Therefore, each coordinate of the Smar tfind
Discrimination Pattern (visible in the Pattern,
Edit and QuickMask Screens) can be turned
white (clear) to accept, or black to reject,
certain targets. White areas of the Smartfind
Discrimination Pattern indicate particular
target coordinates that are accepted, black
areas indicate coordinates that are rejected.
The Pattern shown above is E-Trac’s Factory
Preset Coins Mode Discrimination Pattern,
which represents the typical characteristics
of nonferrous coins; a composite of hundreds
of coins from around the world. It accepts
signals from nonferrous targets and rejects
signals from most ferrous targets.
When an accepted target is detected (e.g.
matching the conductive and ferrous
characteristics of coins), the Target Crosshair
will appear in the white area and a target
response will be heard.
When a rejected target is detected (e.g.
not matching the conductive and ferrous
characteristics of coins), the Threshold will
blank and the Target Crosshair will remain in
the position of the last accepted target.
E-Trac offers a range of Smartfind
Discrimination Patterns (p. 42) which may be
used on their own or in combination.
Smartfind™
Smartfind is Minelab’s unique two
dimensional scale of discrimination. Smartfind
graphically represents both the FE-CO target
properties on the same display.
The horizontal axis rates the target on its size/
conductivity (CO), ranging 1–50 from left to
right. The vertical axis rates the extent of the
target’s ferrous characteristics (FE), ranging
1–35 from top to bottom.
A FE value of 1 represents low ferrous
characteristics and a value of 35 represents
high ferrous characteristics. Similarly, a CO
value of 1 represents low conductivity and 50
represents high conductivity.
Ferrous targets (e.g. nails) contain a large
amount of iron, or some other less common
magnetic material. Because they are
magnetic, ferrous targets generally display
the Target Crosshair at the bottom of the
Smartfind Window.
Nonferrous targets (e.g. pure gold, silver,
copper and bronze) contain little or no
magnetic material. Because they are not
magnetic, nonferrous targets will generally
display the crosshair at the top of the
Smartfind Window.
Note: Even nonferrous targets will generate FE
values higher than 1.
High conductive targets (e.g. large silver
coins, copper items) will cause the Target
Crosshair to appear toward the right of the
Smartfind Window.
Low conductive targets (e.g. small alloy coins,
foil, 9ct and fine jewellery) will cause the
Target Crosshair to appear toward the left of
the Smartfind Window.
The object size will have some effect upon
the conductivity rating for targets. Generally,
the larger the target, the higher the
corresponding conductivity rating.
As the coil passes over a target, the detector
digitally processes the target signals and
displays a Target Crosshair in the Smartfind
Window at the end of detection. The position
of the Target Crosshair is relative to the
target’s conductive and ferrous properties.

Introducing the Detection Screens Pattern Screen
The E-Trac comes pre-programmed with
three unique Detection Screens. The selection
of the appropriate Detection Screen for
the current conditions will depend on your
preferences and experience. The three
Detection Screens are:
– Pattern
– Digital
– QuickMask
All the information required for detecting
targets is contained within these three
Detection Screens, and when combined
with audible target responses, no buried
treasure is safe.
When the detector is turned on for the first
time, the Pattern Screen will be displayed
on the LCD and E-Trac is ready to begin
detecting. Target information is presented to
you via the Smartfind Discrimination Pattern,
Sensitivity Gauge, FE-CO numbers and Depth
Gauge. The information available to you in
the Pattern Screen is invaluable for successful
detecting with E-Trac.
Information is refreshed in ‘real time’; enabling
fast, clear and reliable interpretation of a
potential target’s qualities. With practice and
experience you will be better able to interpret
the information displayed, leading to more
successful detecting.
The Smartfind Window is in the centre of
the Pattern Screen. It displays the active
Discrimination Pattern (p. 21). Above the
Smartfind Window is the area in which
an accepted target’s FE-CO numbers will
appear. During and after a detection, a
Target Crosshair will appear in the Smartfind
Window, displaying the target ’s FE-CO
coordinates relative to the rest of the
Discrimination Pattern. The FE-CO numbers
and Target Crosshair will remain until a new
‘accepted’ target is detected. Display Timeout
(p. 79), in the Preferences Menu, can be
turned on and this will clear detection results
after a five seconds.
The Depth Gauge is located to the right of
the Discrimination Pattern.
The Sensitivity Gauge is to the left, and by
default it is turned on. The Sensitivity Gauge
can be turned off via the Preferences
Menu (p. 78).
The Detect button on the Control Panel
switches between the Pattern and Digital
Screens, and returns you to these Screens if
you are in the Main Menu, QuickMask or Edit
Screen. In addition, the QuickMask button
provides a shortcut bet ween the QuickMask
Screen and the Pattern/Digital Screens (see
diagram below).
The last Detection Screen used will appear
the next time you turn on the detector. Any
adjustments to Discrimination Patterns made
in the Pattern Screen will be retained and
used in Digital as well.

approximately 30cm (12“) from the coil.
Once a target is detected, a crosshair will
appear in the Depth Gauge indicating the
approximate depth of the target.
The Depth Gauge is also updated for
rejected targets.

Digital Screen
E-Trac has the Digital Screen that shows both
the ferrous content (FE; range 1–35) and the
conductivity (CO; range 1–50) of a target.
The enlarged FE and CO numbers are the
coordinates of the Target Crosshair displayed
in the Smartfind Discrimination Pattern.
There is a thumbnail of the active
Discrimination Pattern above the
FE-CO numbers.
To switch between Smartfind and Pattern
displays, press the Detect button. The
conductivity and ferrous information of
the target will clear as you switch between
Pattern and Digital, until a new
detection is made.
Note: When using the Digital Screen, the
Discrimination Pattern is still active.
