Sometimes we miss a fish or we shoot a large fish and the recoil or pull of the animal can pull the gun out of your grip, which ever the case make sure you always use a gun equipped with a shock line. JBL's Shock Line for Magnum JBL4D50 Spear Guns will absorb that pull or recoil that is felt when shooting and spearing a large fish. Shock Line also secures the spear shaft to the gun preventing spear lose.
Shock Line is made of strong and durable braided Spectra Cord assuring you that your spear shaft won't break loose or shock line will not snap when a fish is on your spear shaft. Some of the Shock Line is coiled inside a length of surgical tubing crimped to the line providing a shock absorption bungee effect relieving strain from a fighting fish. Shock Line is 17' 5" (5.31 meters) long and makes a great Save-A-Dive Kit Item.
