Freediving and Spearfishing Fins Bm30 Black-Green 47-48 Seac 71-56NV-47-48
Description:
The SEAC BM-30 is a freediving and spearfishing fin designed for adults who want performance, comfort, and reliable response in the water. It features SEAC’s FRC™ technology, or Fully Responsive Compound, which was developed to deliver blade performance similar to carbon fibre and glass while offering greater durability and flexibility. The blade is made with a two-material construction, combining a stiffer sole for stability with a softer upper section for comfort during longer sessions. Its 30° angled blade helps support both surface finning and the natural ankle position during diving. Small stabilising fins at the end of the blade help reduce sideways drift without reducing power or proper flex. The design uses hydrodynamic and ergonomic shapes to improve efficiency and control. According to the manufacturer, the blade has high resilience and resistance to breakage or permanent deformation, even at low temperatures. The BM-30 fins are 100% Made in Italy and produced in Seacsub’s solar-powered factory.
