Freediving and Spearfishing Fins Bm30 Black-Green 45-46 Seac 71-56NV-45-46
Description:
SEAC BM-30 fins are designed for freediving and spearfishing, combining performance-oriented construction with comfort for extended use. They feature SEACsub’s FRC™ (Fully Responsive Compound) technology, an advanced material developed to deliver a responsive blade action similar to carbon and glass fiber, while offering greater durability. The blade is angled at 30° to support efficient finning on the surface and to follow the natural inclination of the ankles during dives.
The BM-30 blade uses a two-material construction, with a stiffer sole for stability and a softer upper section for added comfort. Small stabilizing fins at the end of the blade help reduce sideways drift without reducing power or flexibility. The design uses hydrodynamic and ergonomic geometries to support efficient movement in the water.
Thanks to the resilience of the FRC™ compound, the blade is resistant to breakage and permanent deformation, even at low temperatures. The fins are also made with a reduced environmental impact compared to common technopolymers and contain no toxic elements. Made in Italy, the BM-30 reflects Seacsub’s focus on technical performance and reliable construction.

Recommended Use:
These fins are well suited to adult freedivers and spearfishers looking for a technical, performance-focused option. They are especially appropriate for users who want efficient propulsion, stable blade control, and comfortable wear during longer sessions in the water. The 30° blade angle makes them practical for both surface finning and diving movements. They are a strong choice for training, recreational diving, and spearfishing in conditions where responsiveness and durability matter.
