The 729 FUEGO fins represent a combination of innovation and tradition. They are modern in terms of energy transmission from the foot to the blade, but traditional due to the shape of the blade itself. The name consisting of 700, just like the new carbon T700 with large squares that it is made of, and 29, as in the degrees of inclination of the blades (25° the inclination of the previous ones), says a lot about these exclusive fins. An essential and advanced design characterizes the 729 FUEGO after years of studies and research applied to biomechanics. Maximum use of energy available, finds its very best application in the 729 FUEGO.
The C4 anatomical footpocket, adjustable and preformed, transmit muscular strength to the blades of the 729 FUEGO in the most natural way possible, pushing through the optimum point, under the metatarsus.
In scuba diving this provides a high level of naturalness and speed without any apparent effort. The energy saving of the 729 FUEGO does not depend exclusively on the elastic action of the carbon fibres, but it is based on the minimum request for energy that this system requires of scuba diving. The concave end piece of the 729 FUEGO’s provides the fins with immediate elastic reaction to the movement coupling. The 729 FUEGO’s favour rapid restarts and traditional fins, in accordance with the requirements of spear fishing. The 729 FUEGO blades extend to the heel of the foot, therefore resulting in excellent energy transmission.
The blades of the 729 FUEGO made from 100% carbon Megaforce T700, a fiber that is 40% more resistant compared with a standard one, combines an excellent level of resistance with elasticity.
More than twenty years of studies, international research and experience are transferred to the curve of the blades of the 729 FUEGO with second generation double parabolic curve D.P.C., achieved by means of an intelligent lamination of layers of carbon duly dimensioned and positioned. The D.P.C curve optimises curving of the blades and the quantity of water processed second by second in accordance with the EVO water rails and according to the availability of strength produced by the combination of our muscles with articulations. Energy savings have reached unique levels, all to the advantage of speed and therefore to our free diving and safety. The less tired we become, the safer we are: this is the condition of passive safety to be pursued at all times.
The 729 FUEGO’s are equipped with shaped water rails, with progressive deformation EVO, patented by C4. The EVO water rails, fitted with a new variable profile that channels water on the blades in the best possible way, creating a partial “tunnel” effect in the end section. This effect hugely improves the break of the screw thread fluids from the blade, reducing turbulence. The water that leaves the blade is contained and guided straight by the exclusive EVO’s, all to the advantage of speed. As a guarantee of duration, the EVO water rails are made from an anti-abrasion rubber band.
The 729 FUEGO’s have blades that are specifically symmetrical, due to the highly superior mechanical and dynamic efficiency of this solution that is completely free of energy dispersion and due to greater mechanical breaking-torsion loading, typical of any possible asymmetries in shape.
Less important loading also guarantees greater duration in the composite time. Asymmetry can be found when it expresses its function to the best, or in the preformed anatomical footpoket.
The 729 FUEGO’s are made from 100% carbon Megaforce T700, a fibre that is 40% more resistant compared with a standard one. They create a high level of resistance and excellent elasticity. The new weave of the T700 Megaforce carbon with large squares, drastically reduces the number of intersections of the weaving that cause viscose friction in the fabric itself. As it is less stiff in weaving, the carbon thread of the 729 FUEGO can express its exceptional elastic characteristics and low energy absorption in the best possible way.
The blades of the 729 FUEGO are connected to the shoes by means of a simple coupling that is blocked by two special screws that cannot be released, providing a guarantee to the mechanical seal and energy transmission. If necessary for transport, the 729 FUEGO’s, just like all of the C4 fins that adopt our preformed anatomical footpoket, are very easy to dismantle, therefore reducing the space that they occupy and also the primary cause for damage in airplane transportation.
The measurements of the 729 FUEGO blades are 830 x 196 mm, the corner of the blades is 29° + 3° of performing of the anatomical shoe = 32° real inclination of the foot-blade.
The 729 FUEGO’s are available in five sizes of the anatomical footpokets: 39/40 - 41/42 - 43/44 - 45/46 - 47/48. The blades are manufactured in three levels of rigidity: 25( soft ) 30 ( medium ) and 40 ( hard ).
