Last week while on full draw on a doe, my string broke, cable flew around and busted my glasses. knocked me off my stand, but luckly had my harness on. The short fall was painless, but the shock of the incident really freaked me out. In 25 yrs of shooting bow, never had or heard of it happening before. After finding cable/string, I noticed the string had a few strings cut and the rest frayed. I then rememberd I had put a couple broadheads in the case last week and they must have come out of the package and cut several of the strings. WEAR YOUR HARNESS. Taz
