Freediving and Spearfishing Fins Bm30 Black-Blue 47-48 Seac 71-56N-47-48
Description:
SEAC BM-30 fins are designed for freediving and spearfishing, combining advanced material technology with a hydrodynamic shape for efficient performance in the water. At the heart of the design is FRC™ (Fully Responsive Compound), a Seacsub technology developed to deliver blade behavior similar to carbon fiber and glass fiber, while offering greater resilience and durability. The blade is thin and responsive, with an elastic reaction that helps support powerful, controlled finning. Its 30° angle is designed to ease surface swimming and follow the natural inclination of the ankles during dives. Small stabilizing fins at the end of the blade help reduce sideways drifting without affecting blade flex or propulsion. The blade uses a dual-material construction, with a stiffer sole for stability and a softer upper section for improved comfort during extended use. The BM-30 is made in Italy and produced in Seacsub’s solar-powered factory, reflecting a modern approach to performance and manufacturing. This model is offered in black-blue and size 47-48.
