This device has been designed to operate with the antennas listed below, and having a
maximum gain of 3 dB. Antennas not included in this list or having a gain greater than 3 dB are
strictly prohibited for use with this device. The required antenna impedance is 43 ohms.
10COIL-F5, 11COIL-F5, 5COIL-F5
The following statement is not relevant to metal detectors but is printed here to satisfy
legal notification requirement:
“To reduce potential radio interference to other users, the antenna type and its gain should be
so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that
permitted for successful communication.”

USING HEADPHONES
Using headphones (not supplied) improves
battery life, and prevents the sounds from
annoying bystanders.
It also allows you to hear subtle changes in the
sound more clearly, particularly if searching in a
noisy location. For safety reasons, do not use
headphones near traffic or where other
dangers are present. This device is to be used
with interconnecting cables/headphone
cables shorter than three meters.

After you have identified a target using a motion mode of detection,
press-and-hold the PINPOINT pad to identify the target’s exact
location. This technique can yield more information about the target’s
shape and size and also find its exact location to facilitate extraction.
PPiinnppooiinntt aass ffoolllloowwss:
11.
.
Position the search coil just barely off the ground, and to the side of
the target.
22.
.
Now move the search coil slowly across the target, and you can
locate it by the sound. The target is located directly under where
the sound is loudest.
NNaarrrrooww IItt DDoowwnn:
11..
To narrow the response further, position the center of the search coil
near the center of the response pattern, but not directly over the
center.
22..
Release the PINPOINT touch pad.
33.
.
Press-and-hold PINPOINT pad again.
44.
.
Repeat this narrowing procedure to narrow the field of detection
further.
NNoottee::
Depth indication is less accurate after
narrowing.
:
:
COIL DRIFT
If you plan to use the PINPOINT mode for continuous searching, realize that
drift will occur over time, causing the detector to gain or lose sensitivity.
Periodic retuning of the detector is required to minimize drift; release and
press PINPOINT again to retune.
TREASURE HUNTER’S CODE OF ETHICS:
e
• Always check Federal, State, County and local laws before searching.
• Respect private property and do not enter private property without the
owner’s permission.
• Take care to refill all holes and leave no damage.
• Remove and dispose of any and all trash and litter found.
• Appreciate and protect our inheritance of natural resources, wildlife and
private property.
• Act as an ambassador for the hobby, use thoughtfulness, consideration
and courtesy at all times.
• Never destroy historical or archaeological treasures.
• All treasure hunters may be judged by the example you set; always
conduct yourself with courtesy and consideration of others

After detecting a target, do the
following:
11.
.
Walk around the target in a
circle.
22.
.
While circling the target,
continue sweeping the search
coil across the target.
33.
.
Sweep once every 30° or 40° of
the circle.
If the tone does not change
and the target ID value is
consistent as you circle the
target, you can be highly
confident of the target’s
identification.
If the tone or target ID
changes as you circle the
target, you may have multiple
targets or an irregularly shaped
object.
If the tone completely
disappears at different angles,
the target may be trash or a
low-value metal.
If you are new to the hobby, dig all targets. With practice in the
field, you will soon identify audible and visual target feedback with
certain types of metal objects.

This bar graph displays the magnetic mineralization factor, or magnetic

susceptibility, of the soil. The depth to which objects can be accurately
y
identified is strongly influenced by the magnetic susceptibility of the soil. High
O4values have a greater effect on detection depth in the Discrimination
Fe
3
mode than in the All Metal mode. For the most accurate Fe3O4reading,
pump the search coil as though you were ground canceling.
The % of Fe3O4ground minerals are displayed as follows:
H – high
M – medium
L – low
VL – very low

The two-digit PHASE number displayed on the screen indicates the type of
ground mineralization. The number is continuously displayed in all
detection modes except Pinpoint, and is continually updated. Ground
conditions can change within a given search area, sometimes slowly, and
sometimes quite abruptly. This number cannot be adjusted by the user.
Some typical ground mineralization types are:
0 – 10 Wet salt and alkali
5 – 25 Metallic iron
26 – 39 Very few soils in this range -- occasionally
some saltwater beaches
40 – 75 Red, yellow, and brown iron-bearing clay minerals
75 – 95 Magnetite and other black iron minerals

This 2-digit number on the bottom-left of the display can represent any
of the following:
• Internal Ground Balance setting (GND BAL): from 00 to 99
• Gain: 20 values from 5 to 99 in steps of 5
• Threshold: 19 values from -9 to 9
• Discrimination Setting: from 0 to 65
• Frequency: 1, 2, or 3
• Audio Tones Selection: d1, d2, d3, d4 or A1, A2, A3, A4
If the user is not moving any knobs or pressing any touchpads, then the
number represents the internal ground balance setting, and “GND
BAL” is illuminated.
“GND BAL” disappears when the user selects a control, and the
SETTING then represents the current value for the activated knob or
touch pad.

While the Target ID provides a target identification, it is not possible to
always be 100% accurate of the buried object’s classification due to
the large variety of buried metal objects. To assist with target
identification refer to this confidence meter.
If the detector is highly confident an object’s classification, all 5 bars

One bar illuminated indicates a very low level of confidence in the

TONES
In Discrimination mode, the F5 indicates target type by audio tone.
The TONES button allows the user to select one
of four different ways to group target types by
tone.
Your selection depends on personal preference
and search objectives. For example, coin
shooters usually select d3 or d4. Relic hunters
s
might select d1 or d2, depending on search
area conditions.
In All-Metals mode
, the TONES button allows the user to vary the pitch of
the base tone.
See page 16 for a detailed description of the tones provided for each
selection.
NOTCH
The purpose of the NOTCH function is to
change the detection status of a target
category.
• If a category was not eliminated from
detection before being “notched,” then
notching the category will eliminate it from
detection.
• If a category was eliminated from detection
before being “notched,” (i.e. a “
covered the icon), then notching the category will return the
category to detection.

READING THE DISPLAY
The Liquid Crystal Display (LCD) shows
the PROBABLE identification of the
targeted metal, as well as the
PROBABLE depth of the target, in
inches.
The detector will normally register a
repeating, unchanging target
identification when a buried target
has been located and identified. If,
upon repeated passes over the same
spot, the target identification reads
inconsistently, the target is probably a
trash item, oxidized metal, or too
deep to be classified accurately. With
practice, you will learn to unearth
only the more repeatable signals.
The segment identifications are highly
accurate when detecting the objects
described on the screen. However, if
you register in a given category for an
unknown buried object, you could be
detecting a metallic object other
than the object described on the
screen, but with the same metallic
signature. Also, the greater the
distance between the target and the
coil, the less accurate the target
identification.

GND BAL — Ground Balance
Control Knob
Rotate GND BAL to change
the detector’s internal Ground
Balance Setting.
By calibrating the detector to
the actual Ground Phase of
the soil you are searching, you
will cancel out signals from the
earth’s naturally occurring
minerals, thereby improving your ability to detect buried metal objects.
The default ground setting is 82.
The knob has no minimum or maximum set point; it rotates
continuously without a stop.
The faster you turn the knob, the more quickly the ground setting
changes. To make small changes to the ground setting, move the
knob slowly, one click at a time.
There are over 1,000 different ground balance settings, but only 100
different numbers are displayed on the screen, as 2-digit numbers
from 00 to 99. The displayed setting will change by one number for
roughly 10 clicks of the knob.
See section on Ground Balancing for a detailed description.
GAIN
The gain control increases, or multiplies, the signal from a buried metal
object.
Rotate the GAIN knob clockwise in order to increase the size of signals
generated. For maximum
detection of the smallest or
most deeply buried objects,
increase the gain. To minimize
the weakest signals, set the
gain at a low level.
There are 20 gain settings. 5 is
the lowest; 99 is the highest.

THRESHOLD
The THRESHOLD control function
varies, depending on the mode
selected.
In DISCRIMINATION MODE,
nneeggaattiivvee
threshold values
suppress sensitivity. The lower the
value, the greater the
suppression. This control can be
used to eliminate electrical interference or to eliminate response from
small trash objects.
In discrimination mode,
ppoossiittiivvee
threshold values amplify the audio
response of weak target signals. Positive threshold selections make
weak targets easier to hear (if, for example detecting in a noisy
location). If it is necessary to reduce sensitivity, reduce GAIN while
maintaining positive threshold values.
In AUTOTUNE MODE, the threshold control can be used in two ways.
For searching at maximum sensitivity, set threshold into the positive
region, with a comfortable background hum volume level. Then
reduce gain if necessary to reduce chatter.
For silence searching, set threshold to a negative number, and also
reduce gain if necessary. Silent searching will result in the loss of
some sensitivity.
Threshold values range from -9 to 9. With the knob at the 12:00position, threshold will be between -1and -3.
DISCRIM (Mode Selection)
• Click into the far-left position,
and the detector enters ALL
METALS mode.
• Click to the right, without
rotating, and the detector
enters DISCRIMINATION mode,
with multi-tone audio target
identification, and no metals
eliminated from detection.
• Rotate the knob to the right
to eliminate unwanted
metals from detection.
Different types of metals will induce different types of sounds,
depending on your TONES setting.
There are 4 choices in DISCRIMINATION MODE:
dd11.

Medium-to-high pitch tone, varying in proportion to
target signal strength. Large shallow objects will
produce a squeal. The variable audio pitch provides
you more information about the detected object.

Iron produces a low-pitch tone regardless signal
strength. Volume varies in proportion to signal
strength. Non-ferrous targets respond as in d1.

balancing. When the phase readout
(verified by pumping the coil over the
ground) is indicating numbers which are
consistently above or below your present
ground balance setting (indicated on the
lower left of the display), you will probably
want to readjust your ground balance.
This is especially important if you’re
operating in All Metals mode.
The Phase readout requires that the search coil be in motion. The most
repeatable measurements can be achieved by “pumping” the search
coil up and down over the soil surface. The presence of metal or “hot
rocks” will result in inaccurate readings. If motion of the search coil
stops, the phase readout will produce meaningless readings.
The numeric scale does not indicate actual degrees, but rather the
scaling of the signals used to balance the ground signal. These signals
are scaled to give the greatest phase resolution in nonconductive soils
high in magnetite, where the greatest resolution is needed.
IINNDDIICCAATTIIOON
Electrical ferrite and magnetite (a naturally occurring form of ferrite) will
usually read about 83. However, due to calibration drift due to time and
temperature change, or the use of different search coils, ferrite may read
anywhere within the total tolerance band of 71 to 99 without significant
impairment of operation. Freshly weathered rocky soils and sands (other
than white beach sand) will usually read higher than 65. Silt and loam soils
will usually read above 55. Red clay soils will usually read above 45 but
lower than 75. Soils reading between 10 and 45 are usually low in
mineralization as indicated by the Fe
conductive, and are often high in smectite clays. Soils in the range of 0 to
10 are rarely encountered other than in a moist saline or alkali environment
with little or no iron mineralization. White sands will usually give no reading.

As you rotate the DISCRIM knob:
• The SETTING value will indicate the target-ID number to be
“discriminated out,” or eliminated from detection. All targets with
an ID less than or equal to the SETTING value will not be detected.
• A “--” will appear over icons for those categories being
discriminated out.
Note that the “--” will appear when all numbers within that category
are discriminated out.
For example, if the DISCRIM knob is set at a SETTING of 55, a “--” will
appear over “TAB.” Those objects in the tab category with values from
36 to 55 will not be detected. Objects with values of 56 and up will be
detected.
The audio and visual target discrimination systems are independent of
one another. In some situations, targets eliminated from visual
detection will still produce an audible response. Also, the audible
target identification may differ from the visual. The audio discrimiation
system provides more information about the target than the visual
system. Understanding the nuance of the detector’s audio feedback
requires some experience.

GROUND BALANCING – Technical Information
What is Ground Balancing?
Why do I need to Ground Balance?
All soils contain minerals. Signals from ground minerals
are often tens or hundreds of times as strong as the
signal from a buried metal object. The magnetism of
iron minerals, found in nearly all soils, causes one
type of interfering signal. Dissolved mineral salts,
found in some soils, are electrically conductive,
causing another type of interfering signal.
Ground Balancing is the process by which the metal detector cancels
the unwanted signals coming from the ground minerals while still
detecting the signals from buried metal objects. This is accomplished
by matching the detector’s ground balance setting to the phase of
the ground signal.
When the detector is calibrated to the soil, the result will be deeper target
detection, quieter operation, and more accurate target identification.

and “EVENED OUT” when you released the button. Also note that
the Gnd Bal setting changed to match the Phase Value, giving
you a visual AND audio Ground Balance confirmation. After
balancing, you can hunt in All-Metals... or return to Disc Mode.
To maintain the best ground balance setting for your detector, the GND
BAL setting on the left of the screen should always approximate the
PHASE value on the right of the screen.
The most accurate PHASE value is the value displayed when “pumping”
the coil over the ground in an area free of metal.

Magnetic susceptibility is expressed in micro-cgs units. In a salt water
environment in the absence of iron minerals, the bar graph indicates
relative electrical conductivity.
In soils with greater than 4,000 micro-cgs units magnetic susceptibility, the
signal from the soil may saturate (“overload”) the circuits. This will not harm
the detector but the machine will not be usable in that condition. The
solution is to hold the search coil several inches above the soil surface so
it isn’t “seeing as much dirt”. By listening and watching you will know how
high you need to hold the search coil in order to avoid overload.
The highest magnetic susceptibilities are usually found in soils developed
over igneous rocks, in alluvial ‘black sand” streaks on beaches, and in
red clay soils of humid climates.
The lowest magnetic susceptibilities are usually found in white beach sands
of tropical and subtropical regions, and soils developed over limestone.
