Speargun Wishbones / Polespear Bridles
Spearit offers a wide variety of wishbones/bridles with special emphasis on increasingly popular cord type wishbones.
More and more spearguns are being designed to use cord wishbones. They have been around for a long time but until recently they were only available on high end spearguns. The slow adoption of cord wishbones has been primarily due to the increased manufacturing difficulty and expense that comes with welding fins onto the spear shaft. The old school notched shafts are easier to manufacturer but the notches weaken the shaft. Prior to the advent of Spectra® and Dynemma® fiber for use in wishbone cord, metal was pretty much the only practical way to go with notched shafts. Metal wishbones have there own drawbacks, they are noisey and present the risk of hand injury if they break. It is a good idea to use cord wishbones if possible. They will work in most cases, even with some notched shafts.
For do-it-yourself spearos, one of the few downsides to cord wishbones has been the difficulty in cramming a 1/4 to 3/8 inch bead or knot into a 1/8 inch hole. Those problems vanished with the introduction of Spearit NTR terminals. The NTR line consists of beads, with rigid insertion stems and inserts that allow you to add the wishbone cord after installation. What makes NTR products different is that they eliminate the need to use of needle nose pliers or knuckle busting T tools to install a cord wishbone and thus the name, NTR (no tools required).
