How to Rig a Hawaiian Sling

A Hawaiian sling is a device used for spearfishing. Slightly less powerful than a spear gun but more powerful than firing your spear by hand, this apparatus functions like an underwater bow and arrow. The spear is threaded through rubber tubing, which is pulled back like a bow. When the tubing is released, the spear is fired toward the prey. Rigging your spear to your sling allows you to keep track of your spear and control larger fish you may catch.

Instructions

    • 1

      Place the spear in the Hawaiian sling and pull it back to the maximum extension you would normally make before firing. Mark the place on the spear just above where it meets the sling.

    • 2

      Drill a hole large enough to accommodate a grommet placed all the way through the spear where you made your mark.

    • 3

      Insert the grommet through the hole and secure it using grommet pliers. Thread one end of the shooting line through the grommet, then knot it securely in place. Tie the knot as securely as possible since you may be rigging for large, strong fish.

    • 4

      Join the spear to the removable head of your sling by threading it through the sling's grommet, and knot it in place. When you fire the spear, it will be rigged to the sling, which will be rigged to the float line.
