Split blade, multi-channel, turbo, techno-polymer construction - fins these days sound more complicated than cars. Although fin effectiveness has improved with materials and design, they're still just tools. Your kick technique still determines your propulsion efficiency.
- Weight yourself properly for neutral buoyancy so you use minimal air in your BC. This reduces drag.
- Use the simplest and most streamlined gear appropriate. Carry or attach only essential gear.
- Swim at a 15-degree angle, with your head up and your fins slightly down.
- Stay at least 3 feet away from the surface or bottom to avoid turbulence.
- Use a steady pace with even leg strokes. Avoid overly long strokes as they are tiring and less efficient than medium ones.
- If you're in high-silt conditions, switch to a frog kick or a scull kick, moving your legs in flat, gentle semi-circles.
