I have the BPS model, its a yellow cyclindrical shape with chains on it. Ive used this one for 20 years and never go fishing without it. It pays for itself on the first trip.

One time I did forget it and got my brand new high dollar swimbait hung. I ended up taking one of my buoys, cutting the weight off, then tying my fishing line to the buoy. I was the first one at the lake the next day, lure retriever in hand, and went and got my bait back.
