Benefits of the Roller Speargun System

The roller system allows you to use the full working length of the barrel for band propulsion, unlike a classic traditional speargun, which uses only part of it. The result is greater shooting power for the same speargun length, or the ability to use a shorter barrel while maintaining the same ballistic performance. The Muzzle 610 is the ideal choice for anyone looking for a reliable Made in Italy component designed specifically for the needs of professional and recreational spearfishing.

Wishbone XL with Bushings - SigalSub

The SigalSub XL Wishbone with bushings is an articulated wishbone for spearguns, made entirely from AISI 316 stainless steel using 4 mm rod stock. Strong, precise, and designed to deliver maximum ballistic performance, it is the ideal choice for anyone using double- or triple-band spearguns.

Construction and Materials

Each wishbone is made from 4 mm AISI 316 Stainless Steel rod stock, hand-bent and shaped to form the engagement hook. A second bend on the arms brings the bands perfectly back in line after engagement on notches or pins. The terminal surfaces remain rounded, significantly reducing the risk of abrasion in the event of accidental release. The version with bushings includes dedicated threaded Derlin bushings (16 pitch), allowing direct use with bands with bushings.

Ballistic Performance

Thanks to its XL dimensions — 65 mm length, 51.3 mm width, and hole center distance of approximately 47 mm — this wishbone keeps the bands perfectly spaced and parallel during loading. This prevents the rubber bands from overlapping, eliminating unnecessary friction and energy loss during the shot, for a consistently clean and precise sight line.

Recommended Use

• Ideal on double- or triple-band spearguns, paired with a narrower wishbone (wire or classic style)
• Also compatible with single-band spearguns, making it easier to engage and slide the hands out
• Pairing with wishbones of different widths to keep the bands perfectly spaced and parallel
• Compatible with shafts with notches or pins

Technical Specifications

• Material: Stainless Steel AISI 316
• Rod diameter: 4 mm
• Dimensions: 65 mm (length) × 51.3 mm (width)
• Hole center distance: approx. 47 mm
• Weight: 16.7 g
• Bushings included: in Derlin, 16 pitch thread, Ø 16 mm
• Compatibility: bands with bushings and tied-in bands

Wishbone Wire with Bushings - Sigalsub

The Sigalsub Wishbone Wire with bushings is one of the highest-performing ballistic solutions available for spearfishing. Developed from the evolution of the "articulated wishbone" designed by Giorgio Dapiran, this articulated wishbone combines a refined technical design with top-quality materials, built for those who accept no compromises in the water.

Harmonic Stainless Steel Wire Wishbone

The attachment system uses a harmonic stainless steel wire with a breaking load of 1800 N/mm², offering the same performance characteristics as the Sandvik steel used in classic Tahitian shafts. Compared to previous systems, this material provides superior elastic return and 20% greater mechanical strength, ensuring maximum reliability on every shot.

Handcrafted Manufacturing and Quality Control

• Each wishbone is made and hand-beveled at the end section
• Individually checked with a 0.3 mm probe to verify closure and hold
• Wishbone bent outward and left open: interchangeable in case of breakage
• Design that eliminates the risk of hand lacerations if the band slips
• Greatly reduces the possibility of accidental line snagging during the shot

Dimensions and Hole Spacing

• Length: 49 mm
• 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.

Wrist Hook - Sigalsub

The Sigalsub wrist hook is an essential accessory for anyone using band spearguns with a roller, pulley-assisted, or inverter system. Designed to make loading pre-tensioned bands easier and safer, this tool is fundamental for every spearfishing session, especially with spearguns featuring high propulsive load.

Composition and Materials

• Corrosion-resistant stainless steel hook, built to withstand use in marine environments
• Wrist bracelet in black rubber, for secure and comfortable anchoring during loading
• High-strength dyneema-coated internal cord
• Compact, lightweight construction, easy to stow with your freediving gear

How It Works

The wrist hook is worn on the wrist using the rubber bracelet. When loading a roller or pulley-assisted band speargun, the stainless steel hook is attached to the dyneema wishbone that connects the bands. By pulling with your arm, you bring the band into pre-load, extending the grip point and allowing you to comfortably reach the wishbones with your other hand for positioning on the loading notches.

Benefits

• Makes loading roller bands significantly easier, even under high tension
• Reduces the physical effort required when loading the speargun
• Allows you to load in stages, increasing control and safety
• Ideal for large-diameter bands and high-power systems
• Quality Made in Italy accessory, manufactured by Sigalsub

Compatibility

The Sigalsub wrist hook is compatible with all band spearguns equipped with roller, pulley-assisted, or inverter systems that use dyneema wishbones to connect the bands. It pairs perfectly with the entire range of Sigalsub spearguns and accessories.
