I was thinking of setting up one of my old compound bows for fishing. I noticed that alot of compound bowfishing rigs from the manufacturer are 0% let off. I was curious why:noidea:. Is there an advantage? Or is a let off a disadvantage? I am using an old Bear Black Mag I got back in 82' (29"/55# about 50-60% let off). I know it will work just fine, I have seen guys set up all sorts of fishing bows. Anyone else out there with a fishin rig? If so, whatcha got?
