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 new Fish Hawk TD gives all anglers critical water temperature and depth information essential for more consistent catches.

The Fish Hawk X4 Replacement Transducer works with the Fish Hawk X4, X4D, or 840 systems. A stainless steel mounting bracket and 30-feet of cable are included (do not cut the cable when installing!)
