| | ArcheryAccessories| Accessories Article | Archers using compound bows often use a release aid to hold the string steadily and release it precisely. This attaches to the bowstring at the nocking point and permits the archer to release the string by pulling a trigger. The "trigger" may be an actual trigger lever which is depressed by a finger or thumb (or held then released) but it may also be some other mechanism. Hydraulic and mechanical time delay triggers have been used, as have "back tension" triggers which are operated by either a change in the position of the release or "true back tension"; that is to say the release triggers when a pre-determined draw weight is reached. A mechanical release aid permits a single point of contact on the string instead of three fingers. This allows less deformity in the string at full draw, as well as providing a more consistent release than can be achieved by human fingers.
