Greetings Jerry,
I have fitted it to one of my compound bows and my grouping is at least twice as good.
I think not having to hold the pull while lining up the target, ready for release, frees the muscles up and more relaxes the body.
This gives the marksman more concentration on target .
I am extremely pleased with the quality of the item and consequently my improved accuracy.
I have yet to show it off to fellow archers that I know.
Many thanks for your interest in my opinion and use of this marvellous device.
Kind Regards,
Raymond C
