The thought of having a psychotrigger appeals to me, but as I use the dead release, pull through triggers won't work. I have resisted the idea of artificially increasing finger, or in this case palm pressure, to trigger a release, because I have been taught to relax my bow hand as much as possible other than keeping one finger around the handle to keep the bow from falling out of my hand when I release the shot.
On the other hand, Tom Clum knows a lot more about shooting the bow than I do, and if he supports this triggering device, it might be worth a try.
Matt Parker's comment about the thing slipping to the side caught my attention. That could be a symptom of a bow handle problem as much or more than a problem with the gadget. I have one bow where I always felt like my hand wanted to slip to the side. After fighting it for years, I finally took a rasp and sandpaper to the handle and reshaped it until it pressed straight back against my hand, and am much happier with it now. Once in a class with Rod Jenkins, he told us that he actually appreciated practicing in the hot muggy south, because if he could shoot his bow when his hand was all sweaty without it slipping, he knew his grip was shaped right.
