THE

The Short Stop System

The Short Stop system is composed of three

SHORT

critical components: the electronic unit, the reel set

screw, and the trolling weight insulator.

 

 

While the downrigger cable is in the water, there

 

is a minute electrical current that flows between the

STOP

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

weight insulators.

 

Stopping the weight at water level eliminates the

 

cable strain caused by bouncing weights or weights

 

hitting the boom end. Stopping at water level will

 

also keep the weight from hitting the boat hull.

The Positive Ion Control System

Your boat has an electrical charge around the hull in water. If a boat is properly bonded and properly zinced, 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 commercial fishermen for many years. This practice has enabled 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 positive charge around their boat. Because of the Lexan® 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 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 mineral content of the water. Your actual voltage may vary.
