Designed for experienced and consistently trained divers, they offer an exceptional blend of lightness, responsiveness, and thrust power, making them ideal for medium-depth to deep dives and long surface swims.

100% Carbon Fiber Blades: High-Performance Double Weave

The blades of the Carbon Pro Ultimate are made from pure carbon fiber with a double fabric weave, a technical choice that is the performance core of this fin:

• Outer layer in 285-T4 4×4 twill carbon: eliminates roughness, cracks, and blade distortion, ensuring complete absorption of the epoxy resin and a structure with high breakage resistance.
• Inner layer in 285-T2 2×2 twill carbon: gives the blade immediate responsiveness and instant return with every kick.
• The selected carbon fibers, combined with the best epoxy resin, ensure stiffness, reliability, and long-lasting durability.

Double S-Curve Flex: The Most Efficient Geometry

The positioning of the internal carbon fiber layers is designed to generate, under pressure, a double S-shaped curve that develops evenly along the entire length of the blade, starting right from the connection with the foot pocket. This geometry is now considered the highest-performing solution for freediving blades because:

• It optimally distributes the power generated by the kick across the entire surface of the blade.
• It delivers a fast, powerful push off the bottom during deep dives.
• It significantly improves performance during surface swims, reducing muscular effort compared with previous models.

28° Angle: Maximum Performance for Trained Divers

• Maintain a comfortable and efficient kick in all conditions.
• Achieve the best dynamic results in combination with the Fireblade Foot Pockets.

Convex Flap and Water Rails: Technical Details That Make the Difference

• Convex Flap blade tip: adds extra thrust in the final phase of the kick, reducing the workload on the legs and allowing you to use less power compared with previous models with a concave tip.
• Low, consistent water rails: work like side spoilers, creating a water channel that prevents the blade from slipping sideways and preserves valuable thrust energy with every kick.
• Smooth, friction-free glossy surface: reduces water resistance and optimizes the overall hydrodynamics of the fin.

Fireblade Foot Pockets: Record Lightness and Exceptional Comfort

The Carbon Pro Ultimate come complete with Pathos Fireblade Foot Pockets, made from vulcanized rubber with three different compounds:

• Soft on the toes and heel: maximum comfort throughout the dive.

The Sigalsub Tsunami are carbon blades designed for freediving and spearfishing, developed to deliver a smooth, progressive, and responsive fin stroke with a good balance between thrust and comfort.

Made from T700 12K Prepreg carbon fiber, they ensure consistent elastic response and efficient thrust transfer, helping reduce leg fatigue even during extended sessions.

The 23° blade-to-foot pocket angle promotes a more natural fin stroke and improves hydrodynamics during descent and ascent.

The reduced side rails allow the blade to work more freely and progressively, increasing flexibility and sensitivity while making the most of carbon’s elastic properties.

Sigalsub Tsunami blades are available in the following stiffnesses:

• Super Soft
• Soft
• Medium

This configuration lets you choose the blade response based on your finning technique and your freediving and spearfishing needs.

Single Blade C4 MB001 CAMOSKIN OCEAN

The C4 MB001 CAMOSKIN OCEAN single blade is specifically designed for spearfishing and freediving, offering a balance of lightness and mechanical strength.

Available in two different stiffnesses, this blade lets you adapt the responsiveness of the blade and power transmission according to individual needs and water conditions.

Fins MB001 CAMOSKIN MED

The MB project represents a renewal of the mid-to-high-end range of carbon fins, faithfully maintaining the traditional technical principles of finning technique in freediving and spearfishing. Within C4’s technical vision, the 200 series represents the highest level of research and development, while the MB001 are the best interpretation of the traditional carbon fin, updated with modern materials and construction solutions.

The MB001 CAMOSKIN MED are equipped with the new 250 foot pocket, a direct evolution of the previous 300 model. This foot pocket is made from TPE 75 ShA overmolded onto a rigid insole, a combination that ensures efficient, direct energy transfer from the foot to the fin blade. Careful attention to geometry has made it possible to reduce thickness and keep overall weight down: the 250 foot pocket in size 41/42 weighs only 250 g.

The result is a carbon fin that combines efficiency, controlled elastic response, and a traditional technical setup, designed for freedivers looking for a balance between high performance and a classic finning feel.

Single Blade FBG Umberto Pelizzari - White

The FBG Umberto Pelizzari single blade in the White version is made of fiberglass, a material known for its excellent combination of lightweight performance and mechanical strength. Available in two different stiffness levels, it adapts to different needs for blade responsiveness and thrust transmission during finning in freediving or spearfishing.

This blade ensures optimal fluidity in propulsion, providing an effective balance between efficiency and control, essential for maintaining a stable hydrodynamic trim during the dive.

Single Blade L-1090 for Freediving

The single blade L-1090 is designed specifically for spearfishing and freediving, available in three different stiffness options to match the thrust and response needs of each freediver.

Materials and construction: Made with selected materials to ensure lightness and mechanical strength, the blade provides effective power transfer and good responsiveness during finning. The choice of stiffness allows you to fine-tune the balance between flexibility and power, optimizing efficiency in the water.

Comfort and hydrodynamics: The blade design is engineered to reduce water resistance while maintaining smooth, fluid movement, supporting balanced trim and improved ergonomics during freediving dives.

• Available in 3 stiffness options to customize responsiveness
• Lightweight materials with high mechanical strength
• Hydrodynamic design for efficient power transfer
• Suitable for spearfishing and freediving

Mounting Kit for Cetma S-Wing Foot Pockets

The mounting kit is specifically designed for Cetma S-Wing foot pockets, ensuring a secure and precise attachment between the foot pocket and blade.

The set includes:

• 2x foot pocket retaining inserts
• 4x self-tapping screws for stable, long-lasting installation
• 4x plastic blade-protection washers 

The kit is sold for one pair of foot pockets, allowing for a targeted, customized installation.

This accessory ensures a reliable connection that optimizes thrust transfer during finning.
