Fins specific for spearfishing, multipurpose, and highly adaptable to different uses. The blades feature a dovetail tip and are featured in three different stiffnesses: 25 (soft), 30 (medium), and 40 (hard). The surface finish is camouflaged. The blades are paired with shoes with a black upper and a military green sole. The water rails are military green.
The Fins 200 features new and specific 100% carbon fiber blades.
These blades are specially designed and manufactured with a new progressive lamination of the carbon fiber layers, a strict technical requirement for these fins.
The lamination combines 4 different types of Japanese carbon fiber, specific for each layer, to optimize the reactivity and resistance of the blades.
The combined use of HT15 carbon externally (exclusive to C4), of intermediate areas with 7 layers of high-strength fabric and a calibrated combination of several unidirectional layers, produces a unique reactivity and exceptional stress resistance.
The resistance of these blades has been tested on our robot, specially designed and built by our technicians (link video piscina), with over 1.6 million complete cycles and a load three times the one produced by human strength.
The specific stratification of the 200 has allowed us to create extremely resistant blades that allow the spear fishermen who start fishing from shore and who often walk wearing their fins, to be able to do it without any fear of breaking them.
The water rails of the 200 fins are not glued but over-molded on the blades with a specific molding process that fuses the plastic material with the composite. This innovative production process, which has never been attempted before on composite materials, was conceived by C4 technicians.
The plastic polymer used to manufacture the water rails maintains elasticity four times more over time than normal NBR, the material commonly used to produce the glued water rails. The over-molding process is an industrial process, perfectly replicated, which avoids any separation that can occur on glued water rails.
The over-molding process has allowed us to create a progressive design of the water rails. The first portion close to the foot features a design ideal for protecting the blade without overloading it with water or limiting its elasticity. Progressively, the height of the water rails increases becoming an effective guide for the fluid threads, thus preventing load drops and unwanted skidding.
