Portable Black Box

The first time I used this product it really seemed to work. I've caught salmon all summer so it is hard to tell if it is helping, but I'm pleased with your service.

I have used it . There seems to he no difference in the fishing experience. The side of the boat with this fishes no different then the side of the boat that does not use one of these

Great addition to the spread. When the writing says 5 to 1 more bites it is true!!! A must have for trolling with down riggers
