solocavediver

Hi,

I stuck this thru a VPM program. It will do the dive, but only if you imitate a Trimix dive by switching fairly soon to air. Here's a profile I came up with (NB it ain't recommended, it's VPM with zero conservatism, plus as the program rightly shows you have to worry about ICD with the sudden switch to air)

Cheers,

Charles.
