Bottom Line Fish Finders 

& 

Cannon Downriggers!

For the ultimate experience, link up the Magnum 20 Digi Troll or the Digi Troll IV with Bottoms Line NCC 6500 and control your downriggers right from your fish finder.
From the Bottom Line Portable Fishin' Buddy to the Tournament NCC 6500, you'll enjoy the high resolution screens and high powerful transducers.
Affordable electric downriggers like the Mini Mag and Magnum 10 (workhorse of the Great Lakes) make trolling with downriggers a pleasant experience.
