Crazy idea, truck mounted fish finders???
How about if a fish finder was invented that could be mounted on a sand sled that would scan the water that is adjacent to the sled as it drives paralell to the water. Like a side scan radar, but it only scans 90 degrees to the right or left depending on which way your driving. Just because it isn't mounted on the bottom of a boat in the water should not matter should it?
