How Deep Am I?

[PaulC]

No Dave, I'm not a techie, closet or otherwise...more like a newbie. The 70m was plucked out of the air as being big enough to make my point - I mean if I started going on about being at 10m when my gauge read 11 people might think I was splitting hairs...I thought my deepest dive was 34m but now I've had your responses I realise that it was in fact 30.6...or something...the nearest I'm likely to get to plumbing the depths is reading that article at http://www.saudidiving.com/deepair.htm that some of you may have come across...
I never got out on the RIB Dave btw...so if you fancy diving locally to you one nite next week I'm gagging to get my feet wet...all I need is a compressor, 3 chords and the truth... :loopy:

Sorry - been away for a couple of days - Dom raises a great point that it is the ambient pressure that counts and not depth. Taking it one stage further though - although your computer will accurately calculate your deco / no deco time, will it still be wrong when it converts that ambient pressure into a depth reading?
