A Black Box is a device used with a downrigger to place a very small electric charge on a downrigger cable. Many species of fish are attracted to this charge. Salmon, trout, kokanee and laketrout are some of these species. Others include halibut, sturgeon, sharks and many others.
The new Pro-Troll Black Box is the newest state of the art Black Box on the market. It has more sensitivity and more features than any sportfishing Black Box ever produced. The latest computer chip technology has allowed most of the functions to be built into the chip thereby improving performance and substantially lowering cost.
