Also if you don't have one of those adaptive algorithm solenoids, each shot of O2 the solenoid gives you, lasts less time on the surface than at depth. You're also susceptible to the conditions at surface (current, waves, etc causing higher consumption).
IMV, being at near surface (or very beginning) is just as dangerous as say,.. a 50m+ deco dive. Worse if you're unnecessarily using hypoxic diluents. |
