(International Patent) The "activa power system" is a Beuchat technological innovatiopn which allows the incorporation of three distict premier material by lamination.
(1) The object is to repkace the vertical support of a traditional which limits the working surface, by two flat dynamic reinforcements to permit the blade to become 100% active.
(2) Lateral stiffeners made from a preformed technopolimer, creating a powerfiul spring effect which generates an ACTIVE rebound equal to no other fin.
(3) Central outflow veins emit variable progressive resistance in relation to blade angle providing controlled fluid motion during the kick cycle.
(4) Balanced power is integrally transmitted due to the reinforced foot cavity and alignment of blade/stiffener (extending into the foot pocket aera).
(5) The difference in stiffness between two elements provides a cupping action associated with thin flexable channels in the blade aera, direct the waterflow and improve directional stability of the kick.
