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.
