Product Overview
For those who demand more from every dive — JCSPORTLINE’s high-performance carbon fiber fins are precision-engineered for professional divers seeking power, balance, and endurance.
Built from aerospace-grade T700 carbon fiber and validated through CFD and FEA simulation, these fins deliver unmatched propulsion efficiency with reduced energy loss.
Designed for both competition and exploration, they represent the perfect synergy of strength, control, and hydrodynamic excellence.
Market Pain Points
| Market Challenge | JCSPORTLINE Solution |
|---|---|
| Standard fins lack consistent thrust during deep dives | CFD-optimized blade geometry provides stable propulsion at all depths |
| Fiberglass fins fatigue easily under repeated stress | Multi-layer T700 carbon structure resists fatigue and maintains stiffness |
| Professional divers need power without bulk | Advanced lay-up design offers high thrust-to-weight ratio with minimal effort |
| Limited OEM support for premium diving equipment | JCSPORTLINE provides full OEM/ODM service with performance testing data |
