Rage Chisel Tip X and SC 3-Blade shock collars prevent the blades on your Rage broadheads from prematurely deploying if you happen to bump your arrow or broadhead while on stand or stalking. Shock collars are designed to break upon impact and will need to be replaced after each shot. Inspect the shock collar for any damage prior to use to ensure proper function. These collars are compatible with all Chisel Tip X and SC 3-Blade broadheads.
