Here ya go Mike. These things are made in Oregon. i used to be able to go down to the guys house and buy the blems real cheap.... but it's been a lot of years since i used those things.... It's the model 10 that i liked the best.
http://spot-hogg.com/files/1713/6614/4738/Model_10_Instructions.pdf I'm not a real believer in target panic, but i've had my issues with getting stuck, and having to force the shot. If you want to call that target panic, i guess i can relate.... The true back tension release with no trigger mechanism would be really tough to use with holding weights 45-55#.
The model 10 release has a trigger mechanism that is thumb activated. it has two settings... one it goes off while depressing the trigger. the other setting is that you come to full draw, depress the trigger.... then slowly applying even back pressure. it goes off when the thumb relaxes.
It teaches you to wait for the shot to happen, rather than consciously pull a trigger.
To some this may seem like an OFF TOPIC issue talking about mechanical release aids. But this type of release when set on relax mode teaches you how to hold even tension on the string and relax at the same amount of back tension every time. it can be an excellent tool for training purposes for learning to keep even pressure on the string with your fingers and let the shot happen rather than forcing the shot.
The NEVER STOP PULLING thing is spot on... but there is a difference between Drawing the bow to anchor, and then "Pulling through the shot" or "expanding the shot" using even back tension.
