The MB001 spearfishing fins from C4 are designed to deliver exceptional performance thanks to their T700 carbon construction.
With a hardness of 25, they combine flexibility and responsiveness, ideal for demanding spearfishers.
The blade size of 806x195 mm ensures efficient propulsion, while the 250 foot pocket, lightweight and ergonomic, guarantees optimal comfort.
These fins are perfect for deep dives and long spearfishing sessions, reducing muscle fatigue thanks to their innovative design.
On the MB fins, the major factor that enhances performance is the new “Reverse Parabolic” slope. The parabolic curvature achieved allows for maximum flex near the foot instead of at the tip of the blade. A completely opposite concept and an evolution from our DPC (Double Parabolic Curve) concept.The slope used significantly modifies the mechanical behaviour of the fin. The surface that generates thrust is greater than the surface that generates hydrodynamic resistance. This allows for greater elastic deformation and superior propulsion. The fin becomes an extension of the foot rather than a mechanical appendage on which force is applied.This advantage is so significant that it allows the use of stiffer blades, thus more efficient, with the same effort as with softer blades.
Made 100% from T700 carbon, the MB001 C4 fins are lightweight and durable, offering excellent resistance and optimal performance in all conditions of your freediving or spearfishing sessions.
For the development of this fin, we started by designing the foot pocket. The MB fins use the new 250 foot pocket, directly derived from the 300 foot pocket.Thanks to the use of TPE 75 ShA polymer overmoulded onto a rigid sole, the 250 foot pocket transmits the energy from the foot to the blade in the best possible way, achieving highly efficient fins.The geometry used allows for a minimum thickness that reduces the weight of the 250 foot pocket to just 250g in size 40/41.
