All Huntmasters know the importance of a D-Shackle, a small piece of stainless steel holding everything together. The exact reason why Huntmaster develops the best Flatlock D-Shackle for Spearos all over the world. Forged in grade 316 stainless steel and a pin that locks into the indentations, you could hunt with your mind at ease that vibrations will not cause the pin to go loose.
These D Shackles can be used for speargun rig ups, invert rollers, floatlines and many other diving applications.
