Following the Impulse project, we have successfully transferred the same design parameters for S-shaped undulating deformation to this innovative fin. This particular movement allows for a notable accumulation of elastic potential energy in the blade, which is released during the return kick, transforming into thrust. The thermoplastic rubber used for the water channeling rails is highly flexible and soft so as not to undermine the intrinsic characteristics of the blade. The Turbo version features a new, innovative foot pocket with shorter side rails, providing an increase in performance. The Gara Modular system introduced by Cressi makes this a perfect choice for deep freediving and spearfishing for divers of all levels. The modular design allows the user to interchange blades for specific diving purposes, making it the perfect fin to grow with, as the diver can change blades as their skills increase. Any Cressi polypropylene, fiberglass, or carbon fiber long blade can be interchanged in minutes without any modifications to either. The self-adjusting foot pocket is constructed using the most modern multi-compound joining process, offering comfort and suppleness around the foot where desired, while also featuring stiffer compounds in the underfoot area and heel region, where power transfer occurs. The Impulse features an innovative design: the blade has a 29-degree angle, providing the ultimate in efficiency during the kick cycle, requiring less energy. Thanks to the angle, the blade will be aligned with your body, increasing the dynamics underwater. The blade is made of lightweight and shock-resistant polypropylene. It features a "Rondine" tail shape for improving control and directionality. The later ribs prevent water flow from escaping sideways. The fin can be comfortably worn with or without neoprene socks. Gara Modular’s foot pocket is wider than the other freediving fins models. we suggest using it with neoprene socks in order to have a proper fit. The product comes with a pair of pre-shaped insoles that can be cut to fit the foot pocket.
