SEAC M-30 Interchangeable Blade Freediving and Spearfishing Long Fins

The M-30 features a high-modulus technopolymer interchangeable blade and a dual-material foot pocket designed for efficient power transfer and comfort during freediving and spearfishing. The 30° angled blade geometry improves propulsion and reduces leg fatigue, making these long fins suitable for freediving, spearfishing, and recreational scuba. Blade interchangeability and lightweight construction balance reactivity with reduced effort in extended sessions.
