Carter's latest 'Safety' Release aid. The Evolution is a fully adjustable trigger-less back tension release that works by pulling through an amount of poundage greater than your holding weight at full draw.
Simply attach the Evolution to your loop, hold in on the safety and draw to your anchor. Let off the safety and continue to pull past your holding weight and experience the cleanest surprise release you've ever felt.
Choice of 3-finger or 4-finger activated.
