I think computers in general are a very good thing. Maybe the right one for
tech diving doesn't exist yet, but if it did it would beat working from
tables any day.

That's my point - it won't be if I keep below the ceiling.

It is aware of my gas changes. I have a Nitek 3, 3 gas computer.

Anyway, I just purchased DecoPlan. I ran the profile of my last dive (145'
for 30 mins on 24% EAN, deco on 50%) and using the default gradient factor
settings it gave about the same total dive time as the Nitek 3, but with a
very different set of stops.

One thing I particularly like about the Nitek is that with the PC logging
program it will calculate my SAC, which for me at this stage is useful to
know across a series of different real dives. Anyone know if its possible to
get it to do this in gauge mode (i.e. it doesn't know about gas switches, so
can these be input later for SAC calculations)?

And a question on DecoPlan. The help says that the gas requirement
calculation includes the reserve, but in non-metric mode the reserve
settings in the preferences are ignored. So is the reserve an extra 50%?

Anyone know if the gas management features that are only available in metric
mode are going to be implemented in non-metric at any time in the near
future?

Ian
