Freediving and Spearfishing Fins Bm30 Black-Blue 45-46 Seac 71-56N-45-46
Description:
The Seac BM-30 is a freediving and spearfishing fin designed for adults who want efficient propulsion, comfort, and reliable performance in the water. It features Seacsub’s FRC™ technology, or Fully Responsive Compound, developed to deliver fin-blade performance comparable to carbon fiber and glass fiber while offering greater resilience. The blade is engineered to be thin and responsive, with no need for reinforcing ribs, helping maintain an efficient hydrodynamic profile. Its 30° angled blade supports both surface finning and the natural inclination of the ankle during diving. The blade also includes small stabilizing fins at the end to help reduce sideways drifting without affecting power or flex. The foot pocket uses a dual-material construction, with a stiffer sole for stability and a softer upper section for comfort during longer sessions. Made in Italy, the BM-30 combines innovative materials and ergonomic design for demanding underwater use. The black-blue colorway gives the fins a sleek, technical look.
