Nemrod,
What a slap by someone who purports to dive Force Fins. I turn the other cheek. How can you tell us other than what we have learned. I have no problems surface swimming with any of the 33 models of Force Fins we currently sell.
When beach diving in California, where we have surf, the goal is to get under and past the waves as quickly as possible. When on the surface there is more turbulence, so we drop down and swim our distances with a compass at shallow depths.
In any regard, the Original, Pro, Tan Delta or our new
Flying Force Fin all have upcurved blades. It is against their resistance and rebound that you are suggesting that you might have to work against at the surface.
This same short, upcurved blade is an advantage when making surf entries and exits. You can enter the waves sideways, and exit running forward with your Force Fins on. This is a much safer and easier profile than walking backwards carrying your fins, and trying to take them on or off when churning in the surf as taught for the benefit of
manufacturers who sell
Terrestris Fins that can torque your knee or ankle if caught in the turbulence of a breaking wave.
Besides, how is it you have no logged dives, your not certified, yet speaking as if you think you are an expert in the use of my products. Well you can lead a horse to water but you can not make it think.
