I just picked up a new toy. It is called a "Fish Hunter", fish locator. I haven't had a chance to use it yet but was just wondering if anyone on the forum has heard of, or got to use one? It is suppose to be good for bank fishing, boat fishing, or whatever. If bank fishing you can attach this to a separate pole and cast to where you are fishing, or if boating, just drag it behind the boat while trolling or drifting. The images are then blue toothed back to your smart phone. No wifi signal needed, and if fits in your pocket.
Their website has a good demo on there that shows the imagery.
