This is the same tether that comes with your SierraBlaster System. The tether is important for safely securing the Blast Heads and a must for inverted blasts.  For inverted blasts the elastic tether can be adjusted to impart cross tension on the  Blast Head creating more friction between the borehole and the Blast Rod thus holding the Blast Head in the borehole even when inverted.  This is another component that may become damaged while blasting so it is a good idea to have a few extra.
