DON'T DO IT, unless you have it tucked away somewhere in a pocket or underneath your outer clothing. Trust me, I am talking from experience. When I was turkey hunting last spring I had my b-nocs around my neck and caught them in my string when I attempted a shot. Long story short, my world got flipped upside down and needless to say I didn't get the turkey. I can't help but to laugh about it now, but it sure wasn't funny at the time and it cost me a bird with my bow.
