Benefits and Applications

Thanks to the stiffness and elastic recovery of Sandvik steel, the Shaft maintains a stable, vibration-free trajectory during the shot, ensuring accuracy in tracking and on impact.

The low-profile pins improve the Shaft’s hydrodynamic smoothness, reducing drag and making it easier to attach wishbones made from different materials.

The recessed Floppers increase mechanical strength without compromising thrust efficiency or penetration in the water—key factors in spearfishing and freediving for properly managing fish retrieval.

Evolution Shaft with Sigal Sub Notches in Heat-Treated Sandvik Steel

The Evolution shaft with notches is manufactured by Sigal Sub using premium-quality Sandvik steel, subjected to a specific heat treatment to improve its mechanical properties. This process gives the shaft the strength and stiffness needed to ensure high accuracy, ideal for use with open- and closed-muzzle band spearguns.

Technical Features and Materials

• The two loading notches use an innovative technique that creates a rounded-profile seat with no sharp edges or cutting corners, improving durability and safety when used with Dyneema wishbones and preventing premature breakage.
• The tail end is hand-finished to eliminate sharp points and edges, ensuring safety and comfort when handling.
• The recessed floppers are made from raw AISI 316L stainless steel, ensuring high mechanical strength. The single flopper, manually modified to prevent it from closing after passing through the fish, is positioned on the top as standard but can also be requested in a bottom configuration.

Available Variants

• Two diameters: 6.25 mm, 6.5 mm
• Single-flopper configuration positioned on top
• Available lengths from 90 cm to 160 cm

Thanks to its construction and the materials used, the Evolution shaft stands out for its high stiffness and elastic rebound, ensuring a stable trajectory with no shaft whip during penetration in the water. It is a precise technical choice for spearfishing and freediving with band spearguns, optimized for long-term efficiency and durability.

Sigal Sub Evolution Threaded Shaft with Notches in Sandvik Steel

The Evolution Threaded Shaft with Notches, manufactured by Sigal Sub, is made from Swedish Sandvik steel heat-treated to improve its mechanical properties, ensuring the strength and stiffness required for spearfishing and use with band-powered spearguns.

Designed for spearguns with both closed and open muzzles, this shaft delivers high shot accuracy thanks to its excellent elastic recovery, maintaining a stable, clean trajectory and reducing shaft wobble in the water.

Main Technical Features

• Material: heat-treated Sandvik steel
• Configuration: threaded for use with prongs and spear tips
• Thread: M7 (7 mm)
• Available diameters: 6.5 mm and 7.0 mm
• Available lengths: from 50 to 115 cm

New-Generation Loading Notches

The notches are not simply milled, but produced using an innovative technique that creates a rounded seat free of sharp corners and cutting edges. This design significantly reduces the risk of damaging Dyneema wishbones, promoting longer service life while maintaining consistent engagement efficiency during underwater activity.

Recommended Applications

Suitable for use with spearguns with both closed and open muzzles, the Sigal Sub Evolution Threaded Shaft is a technical choice for freedivers and spearfishers who require a reliable, durable, high-performance shaft for their dives.
