If necessity is the mother of invention, lack of availability is the father
I've been wanting to try a clicker for a while, but down here in Aus, trad archery stuff isn't easy to find and I wasn't paying 3x the price of the clicker in postage to get one here from the US/UK.
I've tried a few different iterations before coming up with this simple one that takes 5 min to install. It probably won't be a permanent installation here, I will eventually shift it further up the limb to reduce the string length if I decide I like it after testing in the real world (read bush-bashing through thick scrub!). Pics should be self explanatory, but I did wrap it in a couple of pieces of tape to protect the rubber on the quiver and drilled a smaller hole in the other end to reduce the size of knots that was needed to stop it pulling through.
Hope this is helpful for someone else.
