aka Magnus73 Here you go Dave! the string release system attached to my hand and the bow string: according to Wikipedia: Archers using compound bows most commonly use a release aid to hold the string and release it precisely, although finger tabs are also popular with compound bows, especially among older archers who have used finger tabs when shooting recurve bows. The release aid attaches to the bowstring just below the nocking point or at the D loop and permits the archer to release the string by the use of some form of trigger. When such a device was first invented (patent filed in USA, 1879) it was known as a "clutch".[1] The trigger may be an actual trigger lever which is depressed by a finger or thumb (positive), or held then released (negative) but there are numerous types. 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 (the use of the word "aid" can be omitted when context is appropriate) permits a single point of contact on the string instead of three fingers as most commonly used with finger tabs. This allows less deformity in the string at full draw, as well as providing a more consistent release. This is primarily because the most successful types operate with positive pressure, whereas the conventional 'fingers' release is negative pressure. (Some archers prefer three fingers under the arrow with a finger tab, whereas the split-finger approach, having one finger above the arrow and two fingers below the arrow is the most commonly used finger shooting method amongst English and modern North American archers who do not use mechanical release aids.) The mechanical release holds the string by retaining it by some form of gate or loop of cord. The gate or cord is released by operation of the trigger, allowing the string to push open the gate or cord. Consequently, any sideways movement of the string, and hence arrow nock, is likely to be less than if fingers were used, although, if a consistent finger tab release is performed, the differences are often negligible in terms of practical hunting accuracy at ranges up to 30 yards. Once I got use to the device, it is a blast to have, although I did work with the bow using conventional drawback (using 3 fingers: one above the nock and two below) as I see it, the advantage is there is no string twist when using the release system. Thus reducing the side to side flex of the arrow. Does this improve accuracy? I don't know. at 25 yards there is still a large 'zone' to hit. After 30 yards, who knows. Thanks for asking Dave. it made me look this up and think about what I do with the bow and why I do it. Thank you all for the comments and faves. I'm dealing with a sudden cold that has kicked me down. I still go to work but only work a few hours a day, getting the necessary work completed and then going home to rest. bleh!
