Sigalsub shaft HRC Tahitian Shark Fins Single Barb 6.75mm

The Sigalsub HRC speargun shaft has a superior hardness of 48/50 HRc, which makes it tough enough to survive countless hits in the rocks. The HRC is made of stainless steel under Sandvic technology. A plus of this shaft is the precise laser welding of the shark fins, preventing any structural weak spots.  

All HRC shafts come with four shark fins, where the front one serves as a loading assist. All holes are hand polished to prevent abrasion of the monofilament. They are offered with penetration cone.
