I've developed a trigger that will work with the dead release, as taught by Rick Welch. No trigger that depends on movement will work, because with this release there is a balanced pulling at full draw and all conscious movement stops. I could use a tab sear release, but I don't want to be consciously pressing on anything that doesn't have to do with the shot, either.
So I found an app for my iPhone for use in interval training, where people alternate fixed time periods at max effort with fixed time periods at lower effort. I timed my shot sequence from just after my arrow is nocked to release, and found that 5 seconds is my average, assuming a relaxed draw and a two second hold at full draw. For a while I thought it would be 6 seconds, but 5 seconds seems to be more my natural rhythm. I set the app so it would beep every 5 seconds. Or, if I want it quiet, I put the iPhone in my pocket and set it on vibrate; it works fine either way.
So it's actually pretty simple. I nock an arrow and when I hear the next 5 second beep, I start my draw. When I hear the next 5 second beep after that, it triggers my release. In one morning's use, it has virtually eliminated my rushing the shot. It also makes it much easier to let down if I get the jitters before the 5 second beep, whereas before, I probably would have just gone ahead and shot early.
It also works for timing a rest in between shots. If I don't want to shoot an arrow any sooner than 30 seconds after I shoot the last one, I just hold off for 6 intervals. It would be possible to program in the 30 second waits, but if your first shot is at the beginning of a 30 second period, you'd be waiting at the line with people looking at you for a long time. So I thought it would be better to just have a never ending series of 5 second beeps.
When I'm shooting with other people, I will probably have it on vibrate mode. Hopefully, having a little buzz in my pocket every 5 seconds won't be too annoying.
