UNIVERSAL FIT: Spectra shooting line comes in standard 15ft length. Cut to the perfect size and attach with a bowline knot to slide ring or spearshaft. Recommended 1 – 2 wraps on speargun depending on model. RELIABILITY: 350lb break strength hydrodynamic spectra shooting line. This sturdy line is no match for caught fish. Line travels quickly through water. Ensuring fast, accurate shots. SHOCK ABSORBING: Elastic bungee dramatically absorbs energy from the fighting fish. This leads to rapid exhaustion and significantly reduces the chance of losing the fish. QUICK CONNECT: Easy attach loop quickly and cleanly connects to speargun muzzle. No knots required. Simply run loop through speargun eyelet and double up on itself. Loop can be cut at one end of base and knotted off for smaller hole applications.
