The carbon blades are made of pure 285-T4 and 285-T2 carbon fiber. These fabrics have proven to be the best choice for our carbon blades due to the combination of high strength and instant reaction. Selected carbon fibers combined with the best epoxy resin offer rigidity, reliability and long life. The 285-T4 4X4 carbon weave style eliminates wrinkles, cracking and blade distortions and ensures complete resin absorption, while the 285-T2 2X2 internal webbing ensures quick recall. PROCESS Each pair is thermally processed for 36 hours and cured at 8 tons of pressure for 24 hours. This process gives the ULTIMATE carbon blades a glossy surface that minimizes water friction and more responsive performance. The manufacturing process minimizes the disposal of carbon fabric and epoxy resin. LATEST WATER TRACKS The carbon blades offer exceptional performance during deep dives thanks to the side rails. These elastic spoilers work as guides, creating a water channel that prevents the fins from sliding on the sides and saves valuable energy for divers. FLAP-SHAPED EDGE After testing different shapes of fin edges for hundreds of hours, we have come to the conclusion that the ULTIMATE flap-shaped edge not only exceeds the effort of the diver, but also adds an extra boost to the end of the movement of the fin. leg. This element allows the diver to consume less energy, compared to previous models of concave shape. S-CURVE ULTIMATE blades deflect the power created by the diver's movement along their entire length. This was achieved thanks to the internal arrangement of the carbon fabric. The special internal design gives the blades the ability to take a double curved S shape under pressure that offers the best flexibility, efficiency and functionality. ANGLE 28 ° The best fin performance is achieved by increasing the angle of the blade and this requires a well-trained diver who exercises consistently and maintains their physical shape. The 28 ° angle comforts every experienced diver who maintains his fitness condition and brings the best results. ULTIMATE shovels combined with PATHOS liners deliver more dynamic results.
