The Classic Paddle (Blade Fins)
Blade fins are the reliable workhorses of diving. They move a massive amount of water with every kick, giving you immediate feedback and thrust.
- Pros: Precision control (frog kicks, back kicks) and raw power in currents. Ideal for technical diving.
- Cons: Can cause leg cramps and require stronger leg muscles to operate effectively over long periods.
The Efficient Wing (Split Fins)
Split fins work like a propeller. The split allows water to flow through the center, creating lift rather than drag. This mimics the swimming motion of marine mammals.
- Pros: Incredible efficiency with minimal effort. Great for divers with knee issues or long, calm dives where air consumption is the priority.
- Cons: Less effective in strong currents or tight spaces where precise maneuvering (like helicopter turns) is needed.
The Verdict
If you dive primarily in currents, wrecks, or plan to get into technical diving, stick to stiff Blade Fins. If you dive relaxed reef profiles, want to save energy, or have joint issues, Split Fins are a game changer.
