I want to start shooting witha back tension release. I was thinking about getting one with a trigger saftey such as the copper john safe shot. Just wondering what you guys thought about these types of BT releases
thanks

They are great and will make you a better shooter IF you shoot them using true back tension. I learned this summer with a sweet spot, and my shooting improved drastically. If your gonna do this, get a copy of Larry Weis's book called Core Archery. You will probably learn more from this book than any other single source of info short of paying a good coach.

thanks I will look into the book. I get a little nervous about booksteaching techniques. After a lot of should I shouldn't I. Igot idiot proof archery a few months back. I never had a problem with punching the trigger or really even thinking about the release, it just sort of happened for me most of the time. then I read the chapter in the book about it. I could not hit the 10 ring if my life depended on it.
Thanks for the insight

Any type of release can be shot poorly. A back tension release is not a magic cure all. It can be punched as easily as a wrist trigger release.
However, as Rick pointed out, if you do it right, they will make you a better shooter. It's not that they are necessarily better releases, but they do tend to force you to think about your form and what goes into your shooting. There is a lot more to it than just using a BT release.
I shoot mostly a BT release. I'm not the best shooter around, but I am steadily improving. I've learned to shoot all types of releases with good back tension.
Almost any of the hinged BT releases will work for you if you use them properly. I've never had one with a safety, and I've never punched myself. A good release that many have started with is the Zenith Archery Productskit that also includes a video. I notice that you are in Pennsylvania so you have access to Lancaster Archery. They will let you try out releases and help you find one that fits you. They have an excellent selection. You can get the Larry Wise book there also. Larry also holds classes at Lancaster. Check the website.
It will help you if you get some coaching help. Back tension is not especially hard to do, but it sure seems hard to describe.
Your shooting will get worse at first, but you will soon get back to where you are now and continue to improve from there.
Good luck,
Allen
