CRESSI MASTER FROG DIVING FINLET

 

Product description:

Cressi Master Frog Diving Fin has a three-material patented design that combines lightness, high thrust power, comfortable and durable. Soft and comfortable foot pocket, footrest material is made of thermo rubber elastomer material. 

It has a snap blade for high efficiency. The material of the blade is polypropylene (Techno Polymer) and silicone. It is resistant to shock and abrasion. It has a quick-release buckle system that is resistant to impact and corrosion.

It has quality rubber straps. It is reinforced with beams and stiffeners molded from resilient copolymer. Flexible and strong pushing power, anatomical computer designed foot pocket provides ideal transfer of leg-fin pressures. It has an open heel foot pocket design.

MASTER FROG The most technical is the Cressi diving fin,

Made from three different materials fused in a single process made (patented by Cressi). Each is applied to different areas of the wing according to their requirements in terms of flexibility, stiffness, reaction or resistance. In this way, the ideal dynamic required for each area is achieved, achieving maximum lightness and inertia savings without the need to increase thickness. feature can be assigned.

Made of high modulus polypropyleneIts  made wide blade , without any commercial embellishments, retains the original reactivity of polypropylene and its wide surface guarantees a very comfortable advancement with very light movements as well as good stability for the diver in static situations. At the tip of the blade absence of lateral ribs,

The foot pocket has three different volumes with a narrowed middle area so that the foot remains firmly fixed inside and the foot/foot pocket effort is transmitted directly and precisely.

The combination of 3 different materials guarantees optimization of the requirements of each area of ​​the wing:
 

• Flexible elastomer -thermo rubber- (grey colour) : It is applied to the areas where flexibility and elasticity are desired (toe tip of the foot pocket, inner part of the sole and the inner part in contact with the ankle) as it affects comfort. diver's

• Compact elastomer (black color):

• Polypropylene: A material inherited from free diving, whose main feature is the very fast transmission of applied energy. It is applied to the upper and inner area of ​​the sandwich part of the sole. It is very tense and responsive and allows a very agile wing flap and a dizzying progress.  Rubber (natural or thermoplastic), polyurethane, has an effort/performance ratio that is clearly superior to EVA and surpassed only by carbon. It also has great resistance to breakage, to the point that Cressi guarantees it for life for sports use.  ;

 It is the fin that achieves the best performance in dangerous situations (currents, etc.) and allows you to maintain a higher forward speed with a very controlled effort. This fin follows the construction principles and materials of freediving and spearfishing fins, especially the prestigious Gara It is based on the concept that started in development in 2000. It is the fin of choice for instructors, professionals and technical divers. a unique propelling device under any circumstances.  Allows you to easily control the fin in the water, alternative types of flapping, rotating or balancing. It is flexible but not elastic. It is applied to areas that require a rubbery, non-slip but durable and high-resistant composition, such as the longitudinal ribs, the sole of the foot pocket and the foot support band (located in the middle area of ​​the sole of the foot). This material is critical for energy transmission. It connects the point (the sole of the foot) with the nerves into a single piece and prevents the usual energy loss due to the overly flexible components of the foot pocket (heavy, slow thrashing that tires the sole of the foot).
