Fishing With Your Downrigger
After programming your Digi-Troll, release some line
from your rod and reel so that the lure is anywhere from
5 to 100 feet behind the boat. This is called drop back.
Attach the fishing line firmly into the line release. Press
and hold the down key to lower the weight to the desired
depth as indicated on the display or select a pre-
programmed weight depth. Place the fishing rod in the
rod holder and reel up the slack so that your rod has a
slight bend in it. When a fish strikes the lure, the line will
separate from the release. Then you will be free to fight
the fish and bring it in on your rod and reel.
Manual Descent
By turning the clutch knob gently clockwise (toward
the boom), you can let your trolling weight descend as
fast or as slowly as you wish. Turning the knob counter-
clockwise (away from the boom) stops the weight. This
gives you control to let it plunge rapidly or sink slowly to
a predetermined trolling depth. With multiple downrig-
gers, you could start all your weights creeping down,
one at a time, and then stop them each in turn.
Note: In order to track line out, the Digi-Troll must
be turned on.
WARNING—DO NOT TOUCH THE CABLE REEL
WHILE THE DOWNRIGGER IS IN USE!
The Positive Ion Control System
Your boat has an electrical charge around the hull in
water. If a boat is properly grounded and has a proper
zinc anode, that charge should be slightly positive when
measured from ground to the downrigger cable. Positive
Ion Control (PIC) is the use of electricity to control that
charge and its fluctuation so that it is always maintained
at a specified set voltage.
The practice of setting up and maintaining a slight
positive charge on fishing gear has been used by com-
mercial fishermen for many years. This practice has en-
abled some fisherman to increase yield when used
along with other good fishing and boating practices.
Cannon's electric downriggers offer fishermen a big
advantage in being able to stabilize and control the posi-
tive charge around their boat. Because of the composite
construction of the frame, Cannon downriggers are insu-
lated from your boat's hull charge.
When the stainless steel downrigger cable is low-
ered into the water, the natural ionization between the
cable and the boat creates a positive charge of 0.7 to
0.9 volts in saltwater and 0.3 to 0.6 volts in fresh water.
This natural voltage is dependent upon salinity and min-
eral content of the water. Your actual voltage may vary.
Fishing Theory
Cable Terminator
Weight Insulator
The Short Stop System
The Short Stop system is composed of three critical
components: the electronic unit, the reel conductive
path, and the trolling weight insulator.
While the downrigger cable is in the water, there is a
minute electrical current that flows between the cable
and the grounded metal boat components in the water.
When the cable clears the water, this current flow will
stop. The Short Stop system senses this interruption
and turns off the motor. The trolling weight insulator is
used to break the cable contact to the water while the
weight is still in the water. The reel conductive path al-
lows the circuit path to be made through the structure of
the downrigger.
NOTE: It may be necessary to use two trolling
weight insulators.
Stopping the weight at water level eliminates the
cable strain caused by bouncing weights or weights hit-
ting the boom end. Stopping at water level will also keep
the weight from hitting the boat hull.

Control features do not function when
