I have used these divers. Not a huge fan. although they work they dont work as well as jets. If you want to try a newer diver give slide diver lite bite a try. I absolutly love these divers. they have an added trigger arm on the back of the planer that trips when a fish strikes your lure. Everyone here has dragged perch and bass while trolling dipsys and not known they were on there until you bring you rod in. this completely eliminates dragging nontarget fish behind your boat. I havent used dipsys on my boat for 2 seasons and wont go back to them. give them a try.

I am no way affiliated with slide diver in anyway. Just a fisherman trying to help other fisherman out.
