Fish Hunter Sonar

Sure, you can kill an afternoon quickly by simply putting your pole in the water, cracking open a beer, and hoping that you get a bite. But if you're on the water to actually catch fish, it helps to know where they are. Fish Hunter Sonar can tell you. Powered by military-grade sonar technology, this ingenious device is so small it floats, and pairs with a smartphone app that allows you to see where the action is, even while the device itself is up to 80 feet away.
