John Dudley talks about tying a d-loop on his bowstring in part 9 of his 13-part series, Nocked and Ready to Rock. The d-loop, of course is a cord that's attached to the string of a compound bow at the nocking point.The archer hooks a mechanical release to the d-loop, to avoid wear and tear on the bowstring and to ensure consistent interaction between the bowstring and the release.Dudley demonstrates in detail his technique for tying a d-loop in this video.
