The FishTrax Small Boat Fish Finders are All-In-One Kits that makes mounting the FishTrax Series on any small boat, with or without a 12-volt battery source, quick and easy. The waterproof FishTrax Fish Finders are the ultimate small boat fish finders as they are the only 100% waterproof fish finders available today. The FishTrax system also doesn't require a bulky external battery like the competition. The entire system is compact, lightweight, and ready when you are. It's also easily removable with one flip of the suction cup mount so you can take it with you at the end of the day. If you have a power supply on your vessel, add a FishTrax Boat Mount Power Adapter and ditch the batteries.
