• Width: 35 mm
• Hole spacing: approximately 27 mm
• After the first loading, the wishbone closes: stable spacing of approximately 20–22 mm for all subsequent uses

Compatibility and Use

The with bushings version is designed for use with Ø 16 mm threaded bushing bands, ensuring a secure, precise, and stable installation on the speargun. Compatible with shafts featuring both notches and pins.

Why Choose the Wishbone Wire

Wire wishbones naturally offer the best ballistic solution among the different types of wishbones available. The open, interchangeable design of the wishbone simplifies maintenance and replacement, even in the water, without having to untie knots or disassemble the band. An ideal choice for demanding spearfishers who want the very best from their gear.

Sigal Sub Wire Energy Wishbone in Titanium for Articulated Band Assemblies

The Wire Energy wishbone by Sigal Sub is an essential component for articulated band assemblies used in spearfishing and freediving. Made entirely from titanium, it provides an optimal combination of mechanical strength and lightness, ensuring durability and reliability during underwater use.

Technical Features

• Material: titanium, for high resistance to corrosion and mechanical stress
• Dimensions: 37 x 27.5 mm, compact and functional
• Rigid structure with spring-steel wire hook for a clean sight line and precise ballistic performance
• Titanium arms that keep the bands parallel during loading

Benefits in Use

The spring-steel wire hook system helps maintain a stable, vibration-free shot line, improving accuracy when the speargun is fired. The rigidity of the wishbone enables efficient transfer of elastic energy, optimizing power and shot smoothness.

The lightness and strength of titanium promote balanced trim and greater long-term durability, essential features for spearfishing and freediving gear that must deliver consistent performance during exposure to the marine environment.
