How the Positive Ion Control System Works
The PIC system uses an internal circuit that passes
the voltage through the drive train of the Digi-Troll to
the shaft. The shaft contacts the cable by means of
a ball bearing, spring and, lastly, a one direction but-
ton head screw. Care must be taken to ensure contact
between the cable and the screw when replacing the
cable. When using coated cable, 3-4 ft of coating must
be striped when terminating the cable to reel. Take care
in ensuring that the striped portion is in contact with the
button head screw.
The Positive Ion Control system applies a variable
0.2 to 1.2 volts on the trolling cable at all times.
Measuring the Natural Electrolysis and PIC Voltage
on Your Boat
A voltmeter with a scale of zero to one volt will
measure the natural electrolysis. Place the ground lead
of the meter on the motor or the battery ground. Place
the positive lead on the stainless steel downrigger
cable while it is in the water. The downrigger must be
unplugged. The voltage you measure on the volt meter
is your boat’s natural electrolysis voltage. Use the same
set up to measure the PIC voltage; just plug in the Digi-
Troll and adjust the PIC voltage desired.
Using Positive Ion Control
Positive Ion Control is very effective when trolling.
The zone of attraction created at the downrigger wire
will attract the fi sh. It is best to use a short drop back
between the downrigger release and the lure. Drop
backs of 10 to 20 ft. are typical. A drop back of 50 to
100 ft. will entirely negate the effects of the PIC circuit.
Fishing depths greater than 125 ft. may require a slightly
higher PIC voltage. If you return to shallow water fi shing
remember to turn the PIC voltage down again.
The correct PIC setting for best fi shing advantage
varies, depending on fi sh type and location. To fully ben-
efi t from PIC technology, it is important that you experi-
ment with the PIC setting to fi nd the proper voltage for
the gamefi sh in the area.
Maintaining Your Downrigger
Periodically, lightly grease the thrust bearing and
bearing race found behind the clutch knob. Replace the
cable at least every two years.
There are no user serviceable parts internal to the
Digi-Troll. Your warranty will be void if opened by
anyone other than an authorized or factory service
center. For repairs or servicing your downrigger
refer to the Warranty Information section of this
booklet.
