For a RH shooter, when you have the release pivoted a little left it holds the string loop and allows you to draw back the arrow. Once at full draw, you slowly rotate your hand the other way - and at some point, with almost total surprise, the arrow is released. If I was looking down on a RH shooter, I would see the top of his/her hand rotating clockwise . . . and once the release rotates past 12 o'clock or so the loops simply slips off the little half moon hook. Great little tool to guarentee a surprise let off - paticularly if you're coming down with target panic.
