• Color: high-visibility yellow for easy identification
• Included: quick-release system on wrist strap, with stainless steel carabiner and swivels at the ends

How to Use

The lanyard is worn according to the type of dive and the freediver’s setup:

1. Constant weight Freediving: it is preferably worn on the wrist. If no weight belt is used, it can also be worn on the belt.
2. Free immersion Freediving: it is worn on the ankle to ensure freedom of movement and safety during the descent.

Applications

The lanyard is mandatory in constant weight freediving competitions, where it ensures proper control of the descent and ascent along the guide line. It is also strongly recommended during training courses and practice sessions, representing a key element for freediver safety.

Spare Part Line Release Rob Allen

The replacement line release Rob Allen is made from durable plastic, specifically designed for use in freediving and spearfishing.

This component allows quick release of the line, ensuring practicality and safety during breath-hold dives.

The choice of plastic materials ensures light weight and corrosion resistance in marine environments, preserving long-term reliability during underwater use.

Rob Allen Stainless Steel Line Release

Specific Spare Part for spearfishing and freediving, the Rob Allen line release is made from stainless steel, ensuring high corrosion resistance and long-lasting durability even in saltwater environments.

This component is designed for fast, secure line management during spearfishing sessions, ensuring reliability and ease of use underwater.

Eco Tab for Camera Mount Brackets

The Eco tab is a specific component for attaching camera mounts to spearguns used for spearfishing and freediving. Made from AISI 316 stainless steel with an anti-reflective black stainless steel finish, it ensures high mechanical strength and durability in marine environments, reducing unwanted reflections during dives.

This tab can be mounted directly on spearguns with wooden handles. For other types of spearguns, a specific adapter is required to ensure a stable and secure attachment.

Included Mounting Kit

• AISI 316 stainless steel tab
• Spline L
• Plastic locking clip
• Pair of M5 screws
• Pair of M5 nuts
• Pair of wood screws for mounting on a wooden handle

The kit is complete for precise and reliable installation, optimized for camera stability during freediving or spearfishing dives.

Tab for Pikotech Quick Release 3.0 System

The tab is designed for the Quick Release 3.0 quick-release system, specifically engineered for use on spearguns for spearfishing and freediving. Made from AISI 316 stainless steel with an anti-reflective black stainless steel treatment, it ensures corrosion resistance and reduces glare in the water, improving underwater stealth.

The tab can be mounted directly on spearguns with a wooden stock. For spearguns made from other materials, a dedicated adapter must be used, ensuring optimal compatibility with different speargun models.

Kit contents

• L spline tab in stainless steel
• Plastic clip for fastening
• Pair of M5 screws for secure installation
• Pair of M5 nuts
• Pair of specific wood screws

This kit is designed to ensure simple, stable installation of the tab on the speargun, maintaining an efficient quick-release system that is essential for smooth, reliable use during spearfishing.
