This is a clever wishbone arrangement from Freedivers. There can be few things more frustrating than a wishbone breaking while out spearfishing.
Freedivers have come up with an awesome solution.
Step 1) The wishbone knuckles are pushed into each end of the gun rubber aided with a little soapy water.
Step 2) The knuckles are then tied off to secure them in place.
Step 3) Simply push the dynema through the holes of the knuckles, twisting as you do so. This helps them through.
Step 4) Finally tie a figure 8 knot at each outside end of the knuckle to your desired length.
