The Torpedo Diver is a troller's tool providing a simple method of lowering fishing line to precision depths while maintaining contact with the lure. The shape of the Torpedo Diver gives it the efficiency to achieve depths far deeper than would be expected from its weight with minimal drag.
The largest Torpedo Diver will give you a great angle of attack keeping your lure close to the boat turbulence. If you are travelling 2 mph and want your lure down 40 feet you only need to put out 40 feet of line, this gives a great opportunity to attach a fixed slider onto your fishing line. With the largest Torpedo Diver you are targeting the most aggressive fish.
