ABOUT YOUR DETECTOR
The I.D. detector of the future is here! The Fisher Coin Strike brings
you a new level of performance and features that include fast
automatic ground tracking, a precision auto ground balance
system, four-tone ID system, programmability and our new D.P.A.
(Digital Phase Analysis) technology.
Throughout this operations manual, we are going to explain to you
the controls and LCD Display Panel of the new Coin Strike as well as
give you a few tips to get you hunting. As with any new detector,
we strongly encourage that you read the entire operations manual
and call your local dealer with any questions.
The Coin Strike control panel and LCD display is designed to give
you constant control read out. In addition, the Coin Strike provides
a 4-tone audio system to give you more target information.
The rest is up to you. You’ve got the right detector, but you’ll have
to decide where to search and then put in a lot of long, hard hours
searching. And, of course, you’re going to have to learn your Coin
Strike, read this instruction manual carefully and practice often.
Drop us a line if you have any questions, comments or exciting
hunting stories. In the meantime . . .
Happy Hunting!

SETTING UP
Your Fisher Coin Strike is built to last for years. However, it’s a
sophisticated electronic instrument containing state-of-the-art
components. Handle it carefully, care for it regularly, and it will
give you years of dependable service. The Coin Strike requires
little assembly.
1. Unpack your Coin Strike carefully and save the
carton: it may come in handy if you ever have to
return the instrument for service.
2. Slip the lower stem into the center stem section.
3. Adjust the stem length and coil angle so that the
search coil rests flat on the ground about 6 to 12
inches in front of and slightly to the right of your right
foot (to the left of your left foot for left handers). Your
arm should be straight and relaxed, the grip held
loosely (see drawing on next page). The stem length
is adjusted by loosening the lower lock nut and
allowing the spring clip to snap into one of the

holes in the center stem. The coil angle is adjusted
by loosening the nylon wing nut on top of the search
coil.
NOTE: Remember, the longer the shaft, the more you’ll have to
bend your elbow to keep the coil off the ground and the sooner
your arm will get tired. The Coin Strike is balanced for comfortable
searching in a tight semicircle around the front of the operator.
4. With the stem length properly adjusted, wrap the
search coil cable snugly around the lower stem and
the center section. Leave just enough slack near
the coil to allow it to be tilted completely backward
and forward.
NOTE: A loose cable near the search coil may cause false signals,
but don’t wrap it so tightly that it pulls against the housing or the
coil.
Adjust the stem length and coil angle so the coil rests flat on the ground about 6 to
12 inches in front of your foot. Move into your “search” position by leaning slightly and
raising the coil about 2 inches off the ground. This should put the coil about 12 to 18
inches in front of your lead foot.

5. Reconnect the coil cable to the control housing.
Be careful not to cross thread it and make sure it’s
snug, but hand tightened only.
6. With the shaft length and coil angle properly
adjusted, you should be able to move into your
search position by leaning forward very slightly and
raising the angle so the coil rests flat on the ground
about 6 to 12 inches in front of your arm.
7. (When using optional headphones) Plug into the
headphones jack on the control panel.

1. Disconnect the cable from the control housing
and unwind all but the last 12 inches or so from the
stem. Secure the lower end of the cable with a
Velcro strap at least 12 inches up from the coil.
2. Remove the control housing from the pistol grip
by holding the grip with one hand and sliding the
housing toward you with the other hand.
3. Attach the belt clip to the control housing by
slipping it over the brass posts on the bottom of the
control housing and pulling it toward the control
panel to lock it in place.
4. Reconnect the cable to the control housing.
5. The control housing can then be mounted on your
belt or on the optional Fisher Chest Harness.
It is especially important that the cable connector be installed
tightly to prevent false signals during body-mount use. Tight, but
never tightened with anything but your hands.

CONTROL PANEL
6
The Coin Strike control panel is an all new digital I/O System. The
LCD Display provides you with a constant control readout showing
you all of your current settings, much like the knobs of an older
-style metal detector.
1. The POWER button turns the unit ON and OFF. One of the first
things you will notice when you turn on your Coin Strike is the battery
level display. Fresh batteries will show 9 volts; when the battery
level is down to 6 volts, you have about an hour of battery life
left. The detector will not turn on if the search coil is not properly
connected. This can prove to be a timesaving safeguard.
2. The LIGHT button enables you to use your back light for hunting
in dim light situations.
3. The MENU button enables you to enter the “menu mode”, in
which you can adjust any of seven controls with the UP/DOWN
arrow buttons: the iron discrimination level, the threshold level,
the sensitivity level, a wet sand “salt” mode, the volume level, four
independent disc. notches, and the saving or recall of 4 control
setups (including a factory preset mode) with our memory feature.
Notice that when the MENU button is pushed, the active control
blinks — this is the control that can be adjusted with the UP or
DOWN arrow buttons. To move to the next control, just press the
MENU button again. When you have all your settings completed,
press the P/P (MEM) button to return to the search mode.

a. When in the MENU mode, the Iron DISC controlcan be
varied from 0 to 99 with the UP and DOWN arrow buttons. A 0
discrimination setting will allow all metals to activate the tone; a
99 discrimination setting fully discriminates out most iron targets,
allowing only nonferrous objects to activate the tone I.D. in Disc
mode. When hunting, you will choose an optimal discrimination
setting between 0 and 99 that allows you to ignore most of the
iron trash in your hunting area, without giving up any good
targets. Also notice that the constant control readout shows you
approximate settings at all times with a graphical icon, whether
you are in the MENU mode or the search mode.
b. The THRESHOLD control is best understood as setting a “trigger”
point for received signals to exceed (and be acknowledged) or
fall short of (and be ignored). This control can be adjusted with the
arrow buttons between -99 (higher trigger = less excitable) and +4
(low trigger = more excitable). There are a couple of considerations
in choosing a threshold setting: 1) If you prefer to have an audio
threshold tone present while hunting, choose a setting between 0
and +4. This will allow your Coin Strike to react to the tiniest targets in
a low mineralization environment. 2) However, if you plan to utilize
the fast automatic ground tracking feature of the Coin Strike, set
the threshold to a -5 or -10 setting for stable tracking performance
(and even lower in harshly mineralized soils).
c. The SENSITIVITY control can be varied from a setting of 0 to
a maximum of 10 with the arrow buttons when the SENS icon is
flashing. As with most detectors, set the sensitivity higher for best
depth performance in soils that are low in mineralization. As the
mineralization gets worse, lower the sensitivity setting as needed.
We recommend a sensitivity setting of 4 or lower for the most stable
performance if the fast automatic ground tracking is enabled.
Please note that a SENS setting of 0 or 1 will still yield excellent
results.
d. The salt mode can be activated or turned off with the Auto
Ground button. While in the MENU, when the two-digit display
shows “SO”, the salt mode is off. Use this setting for all hunting
conditions except wet sand (beaches) with salt content and NO
black sand (magnetic soil). Press and release the Auto Ground
CONTROL PANEL

button to toggle the SALT mode on (display will show “S1”). Press
and release again to toggle it off. For more beach hunting tips,
see the WET SAND HUNTING section.
e. The VOLUME can be adjusted and listened to when the VOLUME
icon is flashing by using the UP and DOWN arrow buttons.
f. The NOTCH Discrimination (“no” on the two digit display in the
MENU) can be adjusted as follows:
1. The UP/DOWN arrow buttons will allow you to choose which
NOTCH category to alter.
2. Once you have chosen which category to change (FOIL,
NICKEL, TABS, or ZINC), pushing and releasing the ALL METAL/DISC
button turns the NOTCH filter ON or OFF.
- If the square next to the chosen category blinks quickly (on
more than off) that target will be accepted.
- If the square next to the chosen category blinks slowly (off
more than on) that target will be rejected.
- When in the SEARCH mode, if the square is ON, the target is
accepted; if the square is OFF, the target is rejected.
Remember, to exit the MENU mode at any time, simply press the
P/P (MEM) button to return to the SEARCH mode
4. The AUTO GROUND button enables you to achieve a precision
ground balance with one touch. Auto Ground Balance is explained
in more detail on page 15. This button also toggles the SALT mode
on or off while in MENU mode.
5. The P/P (MEM) button is used return to the search mode after
you set all your current settings when it is pushed and released.
As mentioned above, it is also used in Memory mode. If the P/P
button is pushed and held while hunting, the Precision Visual
Pinpoint Mode will be activated.
6. The TRACK button activates the Fisher Track AFS© - Adaptive
Feedback System. This fast auto-ground tracking system, enables
you to adapt to changing ground conditions without giving up
the ability to detect targets!
7. The ALL METAL/DISC button enables you to toggle between two
operating modes: a “true” all metal detecting mode or, with an
