Quadraxial:
-All Deep Apnea blades are manufactured with highest of quality 100% Aerospace grade Carbon Fiber. The Multilayer disposition of the Carbon inside of the core creates a "Variable Parabolic Stiffness" (VPS), resulting in a faster blade response. This delivers a comfortable surface swim and a strong ascend, with considerable less effort, which in turn saves oxygen during each dive.
The main advantage for the spear-fisherman is less vibration while hunting, just small kicks will move you near the fish. The increase of the bottom time will be noticeable and the return to the surface will be quick, all due to the High-Quality Carbon Fiber we are using in our blades and the VPS. Deep Apnea uses a Carbon Fiber Quadraxial Structure which comes with a full 2-year warranty. What does “Quadraxial Structure” mean? It means that our fins have fiber orientation in 0º, +60º, 90º, and -60º angles, making the fins more resistant to the torsion, increasing their durability and performance. Before our fins only had fibers in 0º and 90º angles.
Our Quadraxial blades are all 20cm in width and available in either 85cm or 100cm in length. Available in soft, medium, or hard stiffness.
