Stan Perfex - Resistance release aid

In original packaging with all spares and accessories as new. The size is large, however it feels/fits more medium in size. I use a medium release usually but the medium size in this was to small?

Resistance release means you set the release a couple of pounds over the bow holding weight and just pull through, no trigger or hinge rotation needed. You Draw the bow holding the safety button.

Please look at he pictures as there are two small marks , the index finger location and a small one on the end of the 3rd finger hook, both are very small and hard to photograph. This release is in perfect working order and very adjustable with two finger barrels, a selection of barrel posts and both 3 & 4 finger attachments. A complete kit.

I believe this to be a short neck version, however It feels good and works well. Check youtube for more info!!

Please advise if you need any further info, buyer pays postage
