Pneumatic Speargun Shafts for Spearfishing, Freediving, and Scuba Diving

The hardened, spring-tempered stainless steel 17-4PH shafts, with a Rockwell hardness of 44C, are specifically manufactured for speargun spears and shafts. These shafts offer the best combination of hardness and spring tension while resisting oxidation. With a 9/32" (7.1mm) diameter, they feature a rock point on one end and 6mm threads on the other.

Specially designed with a two-angle cut "Rockpoint" speartip, these shafts provide excellent penetration and maintain their sharpness for longer, even when shot against hard surfaces like rocks and shipwrecks.

The spear includes several components: a stainless steel heavy-duty, thick-gauge 3" barb/flopper, a stainless steel slide ring, a stainless steel spring, a plastic line retainer, and a stainless steel threaded butt adapter.

These 7.1mm (9/32") spears can be used on many pneumatic spearguns that were originally equipped with an 8mm (5/16") spear from the factory. Using a thinner spear can result in a faster shot and increased accuracy. However, it is essential to choose the correct end adapter to ensure a proper fit with your speargun.

The end adapters can be interchanged, allowing you to use this spear with different brands and models of pneumatic spearguns. For example, the Mares Cyrano adapter can be used on any speargun that came from the factory with a 7mm spear.

In summary, these hardened, spring-tempered stainless steel 17-4PH spears offer exceptional performance and versatility, with a combination of hardness, spring tension, and corrosion resistance. The specialized Rockpoint speartip and the range of compatible end adapters make these spears a great choice for pneumatic speargun enthusiasts.
