Carbon Pro Maximum Fins - Pathos

The Pathos Carbon Pro Maximum Fins are the ideal choice for spearfishing in shallow and medium-shallow water, where reaction speed, lightness, and immediate thrust make the difference. Designed as an evolution of the Fireblade and included in the Pathos carbon range alongside the Ultimate and Supreme, the Maximum stand out for their specific flex curve, more compact longitudinal dimensions, and a blade-to-foot pocket angle engineered to deliver excellent performance even for users without an extreme training background.

Carbon Fiber Fabric

The Carbon Pro Maximum blades are made from pure 285-T4 and 285-T2 carbon fiber, a combination that ensures high strength and instant response. The selected carbon fibers, paired with top-quality epoxy resin, provide stiffness, reliability, and long service life. The outer 285-T4 4×4 weave eliminates roughness, cracking, and blade distortion by ensuring complete resin impregnation, while the inner 285-T2 2×2 weave ensures a fast blade return.

Production Process

Each pair is heat-treated for 36 hours at 8 tons of pressure for 24 hours. This process gives the Maximum carbon blades a glossy surface that minimizes friction with the water and delivers more responsive performance. The manufacturing process also minimizes carbon fabric and epoxy resin waste.

C-Curve Technology

The Maximum blades distribute the power generated by the diver’s movement along their entire length. The special internal design, based on the arrangement of the carbon fabric, allows the blades to take on a full curved C shape under pressure, ensuring the best flexibility, efficiency, and functionality. Blade return is instantaneous.

Flap-Shaped Edge

After hundreds of hours of testing different edge shapes, the Maximum flap-shaped edge not only reduces the diver’s effort, but also adds extra thrust in the final phase of the leg movement. This feature allows less power to be used compared to previous models.

Water Rails

The Maximum carbon blades are equipped with side water rails that act as elastic guides, creating a water channel that prevents the fins from drifting sideways, preserving the diver’s energy. The water rails, with a constant height of 16 mm, are positioned along the blades for a total of 27 cm and are intentionally compact so they do not interfere with the flex of the carbon fiber, keep weight down, and avoid making the kick heavier.

24° Angle and Blade Geometry

The angle between the foot pocket and the blade is 24°, a medium value that delivers good performance and makes the fin accessible without requiring extreme training. The Maximum blades measure 62 cm down the center (from the curve under the foot pocket to the tip) and 54 cm along the side, with a maximum width of 18.8 cm inside the water rails. Blade thickness ranges from 0.66 mm at the flap tip, to 0.88 mm at mid-length, up to 1.25 mm in the area in front of the foot pocket, confirming a stiffness progression that optimizes both thrust and return.

The blade tip has a convex profile for improved thrust during the final phase of the kick.

Performance

The Maximum perform exceptionally well both on the surface, where they allow fast progress without tiring the legs, and at depth, with a quick push-off from the bottom and consistent thrust. They are designed for very fast spearfishing in shallow and medium-shallow water, where immediate responsiveness and energy saving are key factors.

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

The 28° angle is designed for experienced divers who maintain good physical condition and train consistently. This angle allows you to:

• Push off the bottom with power and no dead spots.
• 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.
