The Pro-Troll Black Box is a device used with a downrigger to place a very small electrical charge on a downrigger cable. Many species of fish are attracted to this charge including salmon, trout, halibut, sturgeon, shark and many others. The latest computer chip technology has allowed construction of a Black Box that has superior operating features but is substantially lower in cost than any other unit on the market.

The unit comes with the "Black Box Book." This book covers everything you need to know about how to test your boat and set up your Black Box. It explains the principles of the Black Box and why fish are attracted to a downrigger cable that gives off a small electric charge. The book also gives a step by step procedure you can use to determine if your boat attracts or repels fish, and explains how to optimize your boat's charge for each species of fish.
