The Mares Excel Quattro is the perfect combination of comfort and power for recreational divers. The fin uses tri-material construction is made of Tecraclene (Techno-Polymers) and thermoplastic rubber: blade with four channels for optimizing water flow, the center channel is inverted to make better use of the glide stroke. The upper and lower stabilizers help maximize muscle energy conversion. Tecraclene ribs in the foot pocket afford an improved fit and permit more efficient transmission of the kicking action. The foot pocket delivers maximum power and evenly distributes pressure over the foot to minimize fatigue. The foot pocket interior features internal ribbing that improves fit, eliminates foot suction and prevents foot pocket flexing, while transmitting more power to the blade. The elastic Optimized Pivot Blade (OPB) system ensures that the blade is always at an optimal angle during both the upward and downward strokes, giving considerably increased efficiency. A combination of materials and geometry designed to achieve an OPB without apparent hinge points, the elastic OPB causes the blade to flex at an optimal angle during the upward and downward strokes increasing the efficiency of the kicks. All effort is translated into a positive easy thrust. The Excel Quattro uses Mares patented design ABS Plus Buckles (Adjustable Binding System). It only takes one quick movement to easily open or close these buckles, even when wearing thick neoprene gloves. The double button release prevents the buckles from accidentally opening making them the most user friendly system on the market.
