RE: Who uses a loop/nock?
Here's some information that I got from a good source that are Bob Ragsdale's reasons to use a string loop:
-"Eliminates arrow-falloff at full draw.
- Makes nocking point location less critical.
- No need to re-nock after a let-down.
- No serving wear from release aid contact.
- Assures easy one-handloading
- Releases can remain attached and ready to go.
- Eliminates gaps in serving from up pressure on nocking point.
- Controls peep sight rotation.
- Eliminates nock warping due to pinch at full draw.
- Allows release aids to be at an angle rather than only level.
- Makes shorter length bows easier to work with.
- Extends maximum available sight range area.
- Prevents arrow from sliding down the string during the shot.
- Prevents release aid rope slap with high cheek anchor.
- Improves shoulder alignment.
- Loop length can modify draw length of bow.
- Eliminates chin slap from inward swinging release aid ropes.
- Can be used with all non-rope release aids.
- Reduces string vibration noise."
While I agree with most of what is printed above, I must take some exceptions and respectfully question;
- Makes shorter length bows easier to work with.
- Loop length can modify draw length of bow.
If I were to shoot a 20" bow with a 10" loop to get my anchors properly set, would that make a suitable set-up? I don't think so. My face would be too far away from the string to utilize the peep or kisser or other string/component that would allow for better aiming.
If I have my draw length set properly so that my string touches the end of my nose (to the side if you shoot with glasses) and the kisser hits the corner of the mouth, does the loop extend the draw length or change the anchor position of the release hand?
Keep in mind that the proper draw length is having the arm extended to a proper relaxed bend position with the string touching the face. If you add a 2" long loop and then shorten your draw length by 2" (as some suggest), then the string will be 2" away from any anchor point on your face. I have exaggerated examples for effect.
We add a LOT of loops for the positive reasons noted. The loop is normally kept to a maximum of between 1/2-5/8". It is tightened using various methods to apply 100#+. This assures that it will not come loose. If it winds up being longer than 1/2-5/8" after tightening/stretching, we have tools to remove one end, cut it, and retie it. We have never had one slip. The release for the customer is then checked to see if it is too long. If it is, we suggest (if possible) that it be shortened. Most can be shortened.
There are now releases made by about 3 or 4 different manufacturers that cater to loops. These releases have a curved or tapered 'hook' that is easily attached to the loop even without looking at making the connection. They also have the trigger closer to the hook/jaw to compensate for the length of a standard loop.
