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.
