C4 Carbon line release system

The C4 Carbon line release system is designed for carbon spearguns in the C4 range and controls the release of the line connected to the shaft during the shot. The component is engineered to ensure smooth movement, mechanical reliability, and resistance to marine corrosion during spearfishing use.

Construction and materials

The system is made from AISI 316 stainless steel, a material used to provide high resistance to:

• saltwater corrosion
• abrasion
• mechanical wear

Construction with CNC components ensures mechanical precision and consistent performance over time, even with intensive use in salt water.

Compatibility and operation

This model is compatible with C4 Auto-R trigger mechanisms and can be configured on either the right or left side according to the speargun setup.

The system holds the line during loading and automatically releases it at the moment of the shot, helping to:

• reduce friction
• improve reloading speed
• provide greater safety during loading
• prevent line snagging
• prevent premature releases
• limit line twisting

Use in spearfishing

The C4 line release system is suitable for single- or double-band spearguns and maintains a smooth, precise release even under high band load.

C4 Auto-R mechanisms are designed to provide long service life, resistance to oxidation, and consistent trigger sensitivity over time.

Made in Italy.

C4 O-Ring for Sealing Floppers - Elasticity and Durability

The C4 O-Ring are sealing rings made from elastic material with a hardness of 50 Shore, specifically designed for Floppers used in spearfishing and freediving. Their elasticity makes them compatible with any type of shaft, while ensuring long service life thanks to the material’s high mechanical strength.

Technical Features

• Elastic material with 50 Shore hardness
• Compatible with different types of Floppers pins
• Innovative integrated tab for easier grip
• Black color for quick identification
• Greater elasticity than the 60 Shore hardness version

Advantages for Underwater Use

The special tab makes the C4 O-Ring easy to grip even while wearing spearfishing gloves, improving practicality during Floppers replacement or maintenance. The superior elasticity compared to harder O-Rings allows better adaptability and excellent sealing, while maintaining adequate resistance over time.

Applications

Designed for installation on freediving Floppers, these O-Rings ensure effective retention of fastening elements, helping keep finning stable and secure thanks to the correct position of the Floppers. The choice of a 50 Shore hardness material provides an optimal balance between flexibility and mechanical strength for continuous use in underwater environments.
