BM30 Freediving Fins

With the new SEAC BM-30 fins, Seacusb launches the new FRC ™ – Fully Responsive Compound technology .

It all started with the search for a blend of polymers that would allow the San Colombano Certenoli company to produce fins with performances similar to those made of carbon fiber and glass, while eliminating the well-known fragility problems of these composites.

They have therefore arrived at a compound with new mechanical characteristics that Seacsub's design and production experience has transformed into a new technology dedicated to the creation of even higher-performance fin blades.

The FRC ™ – Fully Responsive Compound technology has therefore responded to all of Seacsub’s production needs:

• Negative fins and thinner blades than the previous ones in technopolymer thanks to the fluidity and specific weight of the material.
• The product design exploits the mechanical properties of the compound for an elastic response similar to that of carbon and glass fiber.
• No risk of breakage or permanent deformation thanks to the high resilience and high yield and breaking strength of the compound, even at low temperatures.
• Resistance and high elastic modulus allow you to fully exploit the typical geometry of carbon fiber and glass blades without having to use any reinforcing ribs or protection.
• Reduced carbon footprint compared to common technopolymers used in the sector and total absence of toxic elements.

The peculiarity of the SEAC BM-30 fins lies precisely in this technology that combines innovative materials and hydrodynamic and ergonomic geometries.

The compound used is so elastic and has such a high shape memory that – in a demonstration by contradiction – if we were to observe the blade after having rolled it up on itself, once released it would still have its initial geometry, without any permanent structural deformation that could compromise its performance.

Like the successful Motus series, the BM-30 short-string shoe is made of two different materials, a stiffer one on the sole to provide stability and a softer one on the upper for maximum comfort during prolonged use.

The blade of the SEAC BM-30 fins is inclined at 30° to facilitate both finning on the surface and to accommodate the natural inclination of the ankles while underwater. The small stabilizing fins placed at the end of the blade at the point of greatest water flow prevent the fin from sliding laterally without compromising its correct flexion.

The SEAC BM-30 fins are 100% Made in Italy , produced in the Seacsub factory powered by solar energy .
