Depends which tables you use....Xman:anyone? I am not near any tables and need to find out
That should be time from leaving the surface to leaving the bottom. Bottom to surface isn't counted in the time. So that would be 2 down and 8 on the bottom.IwakuniDiver:NAUI is also 10 minutes.
But that takes in to account time to reach the bottom and time to reach the surface. So, if you were to dive a "perfect" square profile to 130fsw using the NAUI tables and assuming you descend at a rate of 60 feet per minute, and ascended at 30 feet per minute your maximum bottom time would be less than 4 minutes.

Well I don't know NAUI procedures but if their tables are total dive time including descent/ascent/safety then I'm not even sure you'd have time to go to 130ft using 30ft/min ascent speed!IwakuniDiver:I know that the Navy Tables are calculated from the time you leave the surface to the time you leave the bottom but I'm pretty sure that the NAUI tables are calculated using your total dive time and max depth achieved rounded up to the nearest 10fsw.
(BTW Andy, you're right, I just looked again, it's 8)
