If you’ve ever heard someone say his/her compound bow just “blew up” when he/she released the string at full draw, what was the explanation for what happened?
More often than not, bows that “blow up” actually “derail” and the impetus was likely a faulty drawback by the user.
The cause is a misaligned string with the cams. In other words, if a user draws back on the bow, then twists the hand holding the string at an angle and releases, the string will slide out of the thin groove of the cam and likely snap as the force is unleashed through the string.
The video below explains in full detail with a demonstration of how this happens and warns against shooting a bow this way. Find about about bow derailment and whether that is something that is covered by a warranty or not.
