Seac U-1000 are scuba fins designed for divers who demand excellent performance and great thrust. Ultra resistant and suitable for professional use. The research of a special thermoplastic polymer creates a sturdy structure, durable over time and resists shocks, abrasions and sudden changes in temperature. The rubber surface inside the blade undergoes precision bending to displace a greater volume of water (spoon effect) and therefore obtain greater thrust. The foot pocket of the Seac U-1000 fin
