I picked up a Scott Focus release the other day used on ebay. I've been having target panic the last couple years, each year it gets worse, I've read backtension can help. I'll still hunt with a trigger release. Anyway my question is, I can't figure out how the thing works. There's a half moon in there and a set screw you can tread in and out, but the release won't fire under any tension at any setscrew setting (all the way in or all the way out). I did a quick youtube search but nothing popped up. Does anyone know of reference? Scott so far hasn't responded to any emails, and with work I don't get a chance to call during business hrs.
