I don`t own one, but I saw a guy who had one last year and it was a pretty neat rig. He just put it down the hole and we could read the depth, see at how deep the fish were and bottom structure. I`ve been looking at them in Cabelas for a while, but my wifes budget can`t afford one ye Good luck with it, I think you`ll like it. Keep us posted if you would please, thanks
