I was browsing liek I do almost everyday and ran across these. I have never even heard of anything like this before.

Cool idea would like to see if it really works or not. It looks like it just works on a spreader system the string pushes on the spreader piece thus pushing the prongs out from behind the string. Get the chrony out lets see if the FPS goes up!! If it does Quicksilver will be all over them!!

Cool idea, but how much can they really improve accuracy? With a Hooter Shooter and a standard nock you can pound the arrow into the same hole over and over. It doesn't get much more accurate than that.

I am with you HB, I think i would rather work on my form and try to get better accuracy that way before I paid for them things.

How much they can really improve accuracy depends on how well you've got your standard nocks fitted to the string. Nocks that fit right? They do really well, and these nocks probably won't improve anything. Nocks that are too tight really screw up accuracy and cut arrow speed. I'm sure these things would do wonders for that kind of situation.
