Freediving and Spearfishing Fins Bm30 Black-Green 39-40 Seac 71-56NV-39-40
Description:
The SEAC BM-30 fins are designed for freediving and spearfishing, combining performance-focused construction with comfort for extended use in the water. They feature SEAC’s FRC™ technology, a Fully Responsive Compound developed to deliver an elastic response similar to carbon and glass fiber. The blade is built with innovative materials and hydrodynamic geometry to support efficient finning and smooth propulsion. Its 30° angle helps both surface movement and the natural ankle position during dives. The blade also includes small stabilizing fins that help reduce sideways drift without compromising power. The foot pocket uses a dual-material construction, with a stiffer sole for stability and a softer upper section for comfort. Made in Italy, the BM-30 is produced with attention to high performance, durability, and responsible material use. This size 39-40 version is suitable for adult unisex users looking for a technical fin for apnea and spearfishing.
