• Batt Check Switch
When depressed upward, displays condi-
tion of batts on meter number 3. If batts
are ok, meter will indicate .7 to 1.
• Fish Connectors
One, two, or three Fish cables can plug
into the Control Box. Power should be off
when plugging in cables. When the Fish is
plugged into a Connector, it is controlled
by the controls directly below that connec-
tor.
• Meters
Each Fish has its own meter. When a
metal target is detected, the meter swings
up. At a given distance, a small target will
produce a smaller swing on the meter than
a large target.
• Selection Switch
A four position switch which selects the
mode of operation for each Fish.
OFF - When in this mode the Fish and all
controls have no effect on the system. All
unused Fish connectors must have Selec-
tion switch in the Off position.
CAL - When a Fish is plugged into a
connector it must be calibrated before
being used.
SALT - This position is used for searching
in salt water.
FRESH - This position is used for search-
ing on land or in fresh water. This position
gives the search coil the maximum sensi-
tivity available.
• Cal Knob
When the Selection switch is in Cal posi-
tion this knob is used to adjust the meter to
approx .3 on the scale. The Fish is now
calibrated and ready for searching in the
Salt or Fresh position.

OPERATION/CHECKOUT
- Position the coil outside and 5-6' away from any metal.
- Plug the cable from the coil into the Fish 1 connector on the control
box.
- Connect the power cord to 24 vdc ( two 12v car/motorcycle
batteries in series ) and observe polarity.
- Turn the Power Switch on and note that the LED is illuminated.

• Zero Adjust Knob
When the Selection switch is in Search
mode, the Zero Adjust is used to set the
meter to approx .1 on the scale. The Fish
is now ready for searching.
• Sample Pulse Delay Used to reduce the effect (meter move-
ment) of highly mineralized salt water bot-
toms. Set to zero for land and fresh water,
four or five for salt water. Effects sensitivity
for small targets - see chart on page 3.
• Speaker
When a target is detected by any Coil, the
meter swings up from the .1 position. As it
goes past .2 the speaker sounds off. The
higher the meter goes, the higher the pitch
(frequency) out of the speaker.
• Vol Control
Adjusts the volume out of the speaker.
• Earphone Jack
Accepts a standard 1/4" earphone plug
(stereo or mono). Speaker output stops
when earphones are plugged in.
