MASTER ARA is the most technical Cressi fin, which achieves a greater efficiency in awkward situations (currents, etc.) and allows maintaining the highest advance velocity with little effort. This fin is based on the construction principles and materials of apnea and underwater fishing fins, especially, on the concept that began developing this prestigious Gara model. This is the favorite fin for instructors, professionals and technical divers, that found it a great and propulsive unparalleled in any condition.


MATERIALS

It’s made of three different materials merged in the same process (patented by Cressi). Each one is applied on distinct areas of the fin according to its requirements of flexibility, hardness, reaction or resistance. Thus, the required ideal and dynamic feature can be allocated on each area without the need of increasing thickness, obtaining great lightness and inertia saving:

  • Flexible elastomer –thermo rubber – Shore 50º (grey color): it’s applied on areas that require flexibility and elasticity (on the foot pocket’s forefoot, the sole’s interior and the instep area that is in contact with the anckle) because that influences the diver’s comfort.

  • Compact elastomer Shore 90º (black color): it’s flexible but not elastic. It’s applied on areas that require a rubber composition, anti-slip but strong and of great resistance (on the longitudinal ribs, foot pocket’s sole and foot’s head strap). This material links the energy transmission critical point (the instep) with the nerves in a single piece, avoiding the usual energy loss through extremely flexible components of the foot pocket that produce a heavy and slow flutter that fatigues the instep.

  • Propylene: this material, inherited from apnea fins, has as main feature the extremely rapid energy transmission applied and its great structural rigidity. It is applied on the blade and on the internal sandwich sole area. It is really nervous and reactive and facilitates an effective and agile flutter. It has a relationship effort-efficiency clearly superior to traditional materials (natural or thermoplastic rubber, polyurethane, EVA). It also has a great resistance to breaks to the point that Cressi guarantees it lifelong to a sportive usage.


Its wide blade made of high-modulus propylene without any kind of commercial ornamentation, maintains the original propylene reactivity and its wide surface guarantees a comfortable advance with really slight movements, and also a great diver’s stability in static situations. The absence of side nerves at the end of the blade allows dominating easily the fin in the water, to alternate kinds of flapping, turning or stabilizing. The foot pocket has three different volumes, with narrow central area to maintain the foot firmly fixed inside and to make direct and precise the effort transmission foot-foot pocket-blade.


EBS ELASTIC STRAP SYSTEM +Info

It combines new buckles of an essential and hydrodynamic design, adjustable to all Cressi models, with a brand new adjustable strap made of highly elastic pure latex. The latex is the most elastic material from nature and has the quality to extend until 8 times its own length without breaking and with complete elastic memory, that is to say, recovering its initial length. This on the fin’s strap gives us great advantages:

  • Allows a relationship between comfort of placement and fin’s fixing, over systems with springs, exactly because of its high elastic coefficient (X8 vs. X1.5 of the spring).

  • It eliminates the messy need of adjustment that traditional buckles have, a process that not always guarantees a perfect heel fixing, especially with non-experienced divers or stress situations during the equipping process.

  • It allows, maintaining the flapping comfort, a high pressure level over the heel which is essential to obtain a right energy transmission applied to the fin without energy loss because of the “spring effect”. This is certainly its most significant feature because a strap excessively soft, long or without elastic memory reduces drastically the fin’s efficiency.

  • It’s easily replaceable and essential both conceptually and in its production and assembly.

  • The natural latex used is of greatest quality without burdens to affect on its features and it guarantees a high resistance to usage, saltpeter and sun exposure.
