If you're going to use a clicker and your set up is not set up for olympic type riser mounted clickers triggered by arrow tip, the limb mounted clicker is hard to beat. It triggers at an exact point relative to achieving exact expansion. Nothing else comes close to insuring consistent draw length, anchor, and expansion. There are other options, as noted as well as diy easily rigged gadgets like a micro electric button that cost pennies. But, as i said, if im using a clicker, i want the feedback related to proper anchor, draw length, and expansion delivered by a properly set up limb mounted clicker. Jmho.
