BATTERIES
USING HEADPHONES
Using headphones (not included) 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.
TARGET PINPOINTING
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 a

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
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:
• 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

PHASE LOCK
Pressing “Phase Lock” will update the internal
ground balance setting.
We recommend pumping the coil, as described
in the GROUND BALANCING section of the
manual, when using this control. Be aware that
a momentary press of the PHASE LOCK button
will automatically transfer the currently
displayed PHASE value to the GROUND SETTING.
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
might select d1 or d2, depending on search
area conditions.
In All Metal 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.

appears over that category’s icon. After a few seconds, the flashing “--”
will time out and the current target category will be notched.
Practice pressing NOTCH a few times and its function will become obvious.
The NOTCH feature is not available in Auto Tune Mode.
FREQUENCY
Use this control if detector behaves erratically
and you suspect electromagnetic
interference from some other electronic
device. The control will change the detector’s
operating frequency. Press until you find one
of the frequencies which minimizes the
interference.
Choices are:
1 – default frequency

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.

• 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
discrimination system provides more information about the target than
the visual system. Understanding the nuance of the detector’s audio

GROUND BALANCING
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 and quieter operation.

GROUND BALANCING – Technical Information
Understanding ground conditions assists the user in setting up the
machine, knowing when to readjust ground balance, and in
understanding the responses of the machine while searching. The
Fisher F5 provides two kinds of ground data:
mineralization (the greater the amount of mineralization, the greater the
loss of detection depth & ID accuracy; this loss is more pronounced in
Discrimination Mode)
where the ground balance should be set).

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.

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 Metal 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.

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.

DEPTH AND TARGET DISPLAY
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.

SEARCH TECHNIQUES
(in DISC mode)
TTaarrggeett VVeerriiffiiccaattiioon
n
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.
PPiinnppooiinnttiinngg pprroocceessss iinn mmoottiioonn mmooddeess:
:
11.
.
Sweep over target in narrowing side-to-side pattern.
22.
.
Take visual note of spot on ground where “beep” occurs.
33.
.
Step 90° to the side of the target.
44.
.
Sweep coil over same area, at 90° to 1st sweep pattern.
55.
.
This pinpoints the target location with an “X”.
COIL MOVEMENT
When swinging the coil, be
careful to keep it level with
the ground about 1/2 inch
from the surface. Never swing
the coil like a pendulum.

TARGET PINPOINTING
(in PINPOINT mode)
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:
• 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

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.”
ASSEMBLY
