Easy, hands-free release of fish finally done right! Simply slide the tube down your tippet until the fly is inside the tube. A quick pop or jiggle and the fly is free from the fish. A huge advantage of this set-up is when a fly is twisted or obstructed from the tube, you can simply use the clamp in the traditional way to remove the hook. Can easily handle all streamside tasks. Match the size and type of flies you use to the release tube size. 5" Clamp with 5mm ID tube (best for hook size #16-#22) or 6" Clamp with 8mm ID tube (best for hook size #8-#18).
