Dyamant Shaft

Dyamant Shaft in 17.4 PH Steel for Spearfishing

The Dyamant shaft is made from 17.4 PH steel, a highly resistant material of certified quality, ensuring strength and rigidity. CNC machining ensures perfectly straight and smooth bars, essential for precise power transfer during spearfishing.

This shaft is equipped with hydrodynamic floppers featuring an innovative welded-pin mounting system, designed to optimize penetration into fish flesh and improve catch efficiency. The flopper design helps reduce drag in the water, improving shot fluidity and speed.

Technical Features

• Available in 6.25 mm diameter and in 105 cm and 125 cm lengths.
• Features 3 low-profile pins suitable for spearguns with closed or open muzzles, compatible with the dyneema system and other types of wishbones.
• The pins are positioned 60 mm, 90 mm, and 200 mm from the rear of the shaft for balanced force distribution and optimal line attachment.
• The raw AISI 316 stainless steel bridge is positioned in front of the fins, 220 mm from the rear, designed to make line attachment easier, even with larger-diameter lines, thanks to a line passage that is 2.1 mm wide and 8 mm long.
• Available with a recessed lower single flopper to modify hydrodynamics and penetration.

Versatility and Use

The Dyamant shaft stands out for its high precision and versatility, making it suitable for various types of traditional band spearguns. The specific pins make it easy to use with dyneema wishbones, allowing quick and secure line attachment.

The bridge, strategically positioned in front of the fins, allows the line to be tied securely when hunting sizable prey, offering greater control during retrieval.
