Just as a warning if you dont already know....in order for structure scan to give you a good picture of whats going on down there you have to be traveling at least 2-3 knots consistently for however long you want to scan the bottom. Its probably going to be pretty difficult at best on a paddle kayak. Gotta remember your also going to be dragging the huge LSS2 transducer in the water as well. But if you figure out how to make it work....
