Let-Off A compound bow uses cables and cams to store energy and reduce the holding weight at full draw This reduction in holding weight at full draw is called “let-off,” and is calculated as a percentage of the overall draw weight For example, a 40-pound bow with a 75 percent let-off would be ten pounds at full draw Apr 6, 2017
