I have one. Picked it up from the Angler's Pro Shop/LFT in Emory. It makes it a whole lot easier to take the prop off and check for fishing line. I'll leave it to the experts on the sound, but if you're ever in a situation on the water where you need to get the prop off the TM, I think this will be nice to have. I was worried about additional weight slowing the prop down, but haven't had any issues in big wind. My
is that it works and is not a gimmick.
