Well I started to double anchor last week and already improved my accuracy. I have a kisser button and a peep sight on my Matthews Q2xl. I use my kisser button to anchor and I also anchor the string on the tip of my nose. Then my trigger finger hand anchors on my jaw/cheek bone. By anchoring this way I get a much more accurate release. I never really paid a whole lot of attention to anchoring to my jaw/cheek bone with my trigger finger hand, but since I started my groups have tightened up. How many of you double anchor? You should give it a try. Anchor that trigger finger hand to your jaw/cheek bone area.
