Cannon Digi-Troll(TM) IV is designed for serious sport fishermen who demand the ultimate in downrigger technology.

 

Digi-Troll IV is equipped with Positive Ion Control which allows you to attract more fish by creating a positive field of ions around your boat. Adjustable voltage lets you regulate the strength of the electric field.

 

Digi-Troll IV's electronic control lets you program three descent and retrieve speeds and five different depths, then access them at the touch of a button. Its cycle-function will jig your bait or lure up and down at a predetermined depth and time interval—a feature West Coast fishermen find particularly effective for Pacific salmon.

 

Digi-Troll IV's expanded bottom tracking mode is more sensitive than ever before. Digi-Troll follows the bottom contour, and keeps your weight at a preset distance off the bottom—even though the contour changes as little as one foot. The unit can be programmed to minus 50 feet to compensate for blow-back and allow truer bottom tracking. Digi-Troll IV's Depth Display Screen shows you the true bottom depth.

 

Install one Digi-Troll IV which can be linked to a transducer, and all your Digi-Troll IV's (slaves) can be linked to bottom tracking through the logic relays. You can run multiple sets at different depths, say, the master unit at 30 feet off the bottom, units one and five at 10 feet, and units two and four at 6 feet. They'll remain that distance from the bottom, no matter how the contour changes.
