my first shot at a deer with a compound bow, and I think everything went wrong that could have. Glow knock didn't work, terrible shot at 26 yards and 25 is my first pin. My wife who was working the camera said she heard an extra click as soon as the arrow left so we don't know if the mechanical broad head flew open before impact and went crazy in the air because I missed like a foot high and 2 feet back from where I aimed. This is what normally happens when I practice if a band breaks on the broad head before impact but who knows. Could have just been a terrible shot on my part.
