Bottom Line Fish Finders

Cannon Downriggers!

The Cannon downrigger line of products is built tough, from the affordable Easy Troll 2 to the sophisticated Digi Troll IV.
Cannon downriggers can be controlled by the NCC 6500 and the NCC 5300. 
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.
