diveplan really is a killer app. for the psion and is the best deco s/w for a
handheld IMO.
Anyone considering a sub $500 dive computer should consider a Psion5+ Gregs
diveplan + timer

when not diving can send emails/surf and have a very versatile personal
organiser all on a *very* stable platform MS free ;-)

The psion is not waterproof, but mine has taken a beating out in the English
Channel and not missed a beat.

It is buhlmann/gradient factor model, and has some other utilities
for gas mixing, etc.  The website currently shows v1.06.  There is
a later version which I haven't got round to uploading yet. :-(

Being written in OPL, it has a minimal user interface, and is slow.

I'm currently working on a new version, written in C++, which
has full access to the Psion GUI, and is much, much nicer to use.

Since the Psion has no native floating point support, I'm
in the middle of rewriting the algorithms to use integer
only arithmetic which should speed it up enormously.  I hope to
finish this by next week, and I'll then distribute it to
my favourite beta-testers for feedback.
