Freediving vs scuba
Jul. 23rd, 2015 05:12 pmAfter I tried scuba, it took me a while to understand why I still like freediving more. The main reason is degrees of freedom.
A scuba diver has the following degrees of freedom: buoyancy (1), forward-backward(~0.5), roll (~0.5), yaw(1), pitch (~0.5) - total 3.5
A freediver has foward-backward (~0.5), roll(1), yaw(1),pitch(1), buoyancy (~0.5) - total 4.
Plus speed of manoeuvre is so different!
Did I miss something?
