This line guide mounts on the muzzle at the bands elevator, allowing the shaft to be secured on the first wrap of line or monofilament, rather than on the second as standard.

Technical Features

• Stainless Steel AISI 316 for high corrosion resistance in marine environments
• Optimal positioning on the speargun muzzle at the bands elevator
• Allows a direct and secure attachment of the shaft on the first line wrap

Functional Benefits

By integrating this line guide, loading the C4 speargun becomes faster and easier. The system improves line management during the loading phase, reducing preparation time and increasing efficiency in the water.

The solution adopted is inspired by that used on most spearfishing spearguns currently on the market, ensuring smooth, practical use specifically for freediving and spearfishing.

Conversion Kit

This in-house manufactured kit allows you to modify the original muzzle of the Graphite and Urukay models, which do not feature a line guide, converting it into a muzzle equipped with this technical element, essential for optimizing shaft attachment on the first line wrap.

Custom Band Preparation for Spearguns

Custom Band Preparation consists of the professional calculation, cutting, setup, and assembly of bulk bands, available in our catalog specifically for spearfishing.

The service is available for both circular and in-line bands, with assembly on metal or textile dyneema (or spectra) wishbones. You will receive the band ready to use on your speargun or roller.

The rubber needed for the preparation must be purchased separately in the dedicated bands section.

Information Required for Preparation

To ensure accurate setup, you must send the following details to info@deepbluesub.com, or to our WhatsApp number +393714213046:

1. Brand, model, and length of the speargun
2. Brand, model, diameter, and length of the shaft
3. Distance of the shark fins (or notches) from the speargun muzzle (hole or rubber anchoring point)
4. Preferences for shot and loading: progressive/soft, medium, or reactive

Available Variants

• Circular Band Preparation
• Circular Band Preparation with Hi-Tech Wishbone
• In-Line Band Preparation
• In-Line Band Preparation with Hi-Tech Wishbone

Technical Preparation Process

The preparation includes the precise calculation of the band’s cut length based on:

• Speargun dimensions and overall mass
• Type and specifications of the shaft
• Diameter and type of rubber selected
• Ideal stretch factor to ensure the right shot

After calculation, the technical preparation is carried out:

• Grinding of the ends or preparation of the cones
• Tying the bands onto metal or textile wishbones
• For textile wishbones, additional processing aimed at reducing bulk with the speargun loaded, improving hydrodynamics and handling in the water

All operations are carried out by specialized technicians to ensure precision and reliability with no intervention required by the user.
