Alright, so i was wondering if anyone knows how to swim faster..? I'm going down a 30 foot hole with some friends who do scuba-diving, I'm afraid that i'm gonna have to come up for air, and i wont be able too because im not fast enough.. i use the finfun Monofin and i'm using this tail skin

I know it probably doesn't matter about tail skin xD

any tips on how to swim faster? whenever i start Needing breath i swim up as fast as i can if i'm deep.
