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 fi shing line fi rmly 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
fi shing rod in the rod holder and reel up the slack so that
your rod has a slight bend in it. When a fi sh strikes the
lure, the line will separate from the release. Then you
will be free to fi ght the fi sh 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 fl uctuation so
that it is always maintained at a specifi ed set voltage.
The practice of setting up and maintain-
ing a slight positive charge on fi shing gear has been
used by commercial fi shermen for many years. This
practice has enabled some fi sherman to increase yield
when used along with other good fi shing and boating
practices.
Cannon’s electric downriggers offer
fi shermen a big advantage in being able to stabilize and
control the positive charge around their boat. Because
of the composite construction of the frame, Cannon
downriggers are insulated from your boat’s hull charge.
When the stainless steel downrigger
cable is lowered into the water, the natural ionization be-
tween 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 mineral 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 fl ows between the cable
and the grounded metal boat components in the water.
When the cable clears the water, this current fl ow 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.
NOTICE: Short stop and Positive Ion
Control features do not function when
spooled with monofi lament or super
lines or if the boat is not properly
grounded.
