Seac L-30 Black are high-performance long fins designed for freediving, spearfishing, and recreational scuba diving. The blade, made from high-reactivity technopolymer, delivers immediate, powerful, and fluid thrust with every kick, while the next-generation L-30 foot pocket without lateral rails ensures a comfortable fit even when worn barefoot. The 30° angle between the foot pocket and blade reduces muscle fatigue, optimizes effort, and improves performance in both freediving and scuba diving. Versatile, technical, and of the highest quality, the Seac L-30 Black are the choice of freedivers, spearfishers, and scuba divers looking for a reliable, high-performance long fin.
