| Re: How deep to you dive on air diluent? For me 30metres used He in Egypt on the Roslie Muller even at 7pence a litre it was cheap diving. I can see know point in paying for a dive not to remember it after. I never used to suffer from narcosis then I did a gas dive the difference for me was huge. I would not dive deeper than 40metres on OC in Britain without He, on CCR 30metres max. . |
