best lure retriever I have used. I have thrown crankbaits in the summer on drop offs for close to 30 years and I had a weighted retriever of some kind, don't remember what it was, but I got most of my baits back when I hung up. I got this one a few years ago and have not lost one bait since I got it and I fish crankbaits for bass a ton in June and July. I put a larger diameter rope on mine, not a lot bigger but a little bigger.
Cool thing about this one is it rarely messes the line up. The other ones I have had I always had to retie when I got the lure back.
