Low Profile Plastic Wishbone Inserts
These low profile plastic wishbone inserts simplify making your own speargun bands. They insert easily into the rubber tubing, and are held securely inside the band with a simple constrictor knot. Wishbones tend to deteriorate before rubber bands due to friction with the spear notches or tabs, the wishbone inserts eliminate the hassle of retying the bands to replace the wishbone. A worn Dyneema wishbone is replaced by simply tying a knot at each end. When the band rubber deteriorates and needs to be replaced, the wishbone inserts are reusable with your next set of bands.
The advantages of these wishbone inserts compared to others is their small size and light weight, which translates into more efficient speargun bands.
