This thing was at my local sporting goods store. You tie it to your line and throw it out and it reads the depth of were you casted and the water temp. Has anyone ever seen and or used one of these. I don't have boat with a depth reader.
So I figured it would be great to use on some of these private ponds, that I have no idea contour of the bottom depth wise. Anyone have anything like this and is it worth having or is it a waste?
