First of all never draw a bow with a release aid without a arrow on the rest. This is just common practice!!! I have seen where some smaller dia. D- loop material will slip thru the jaws of certain release heads. I have seen it happen on a Scott Mongoose, and on one of the tru-ball releases in the past. If you have to draw to check out your equipment make sure to point in a safe direction or downward with an arrow nocked. As Sage noted check to make sure your trigger sensitivity is set. To light can cause a release to misfire as well.
