SEAC BM-30, Long fins with Interchangeable Blades for Freediving & Spearfishing, Made in Italy, black/green, 8-8.5

Description

• SEAC BM-30 is a truly unique fin. Its uniqueness lies in the combination of innovative materials and hydrodynamic and ergonomic geometries
• The BM-30 fin uses a unique, lightweight technopolymer with carbon-like performance, high elasticity, and shape memoryreturning to its original form even after being rolled, without any permanent deformation.
• The BM-30 blade is angled at 30, enhancing surface kicking and aligning with ankle positioning. Its thin, variable profile ensures optimal flexion, while end stabilizers prevent sideways drift without affecting blade performance.
• The material of the BM-30 foot pocket. Like the successful Motus series, the BM-30 foot pocket is made of two different materials, a stiffer one on the sole for stability and a softer one on the upper for maximum comfort during prolonged use.
• The geometry of the BM-30 foot pocket. The BM-30 foot pocket is optimized to accommodate blades angled at 30. The short water rails enable the technopolymer of the blade to express all its reactivity and flexibility.

The SEAC BM-30 is a unique fin that combines innovative materials with advanced hydrodynamic and ergonomic design. Its blade is made from a lightweight, responsive technopolymer that mimics the performance of carbon fiber composites while avoiding their fragility. This material is highly elastic and features excellent shape memoryso much so that the blade returns to its original form even after being rolled up. The BM-30 blade is angled at 30, which enhances both surface swimming and underwater performance by aligning naturally with the divers ankle position. Its ultra-thin, variable profile ensures optimal flexion, while small stabilizers at the blade tips prevent lateral drifting without affecting movement efficiency. The foot pocket design follows SEACs proven Motus series, using two materials: a rigid sole for stability and a softer upper for long-lasting comfort. Its also specifically shaped to accommodate the 30 blade angle. Short water rails further support the blades reactive properties by allowing the technopolymer to flex freely. Overall, the BM-30 fin stands out for its superior materials, refined blade geometry, and ergonomic foot pocket, offering divers a high-performance solution that blends power, comfort, and durability.
