Add to this list the Cochran Nemesis (a wireless, air-intergrated
computer).  It samples depth every 5 seconds or so (I believe) for 34
hours of information.  You need a PC interface to get at the
information.  I've had the oportunity to try a Nemesis and I like it
very much, but I don't have access to the PC interface, so I can't
download my dives.  (I may buy the interface if it's not too
expensive)


Also, in the "non-computer" variety, there is the Citizen Hyper
Aqualand.  I just bought one of these.  It's a digital watch/depth
guage (water resistant to 200M) that logs 30 dives (max depth, ave
depth, start time, end time, date, length of dive (minutes), dive
number, minimum water temperature, all available from the watch).  In
addition, using a PC and the included software and interface you can
download profile information for the last six hours (depth every 5
seconds, water temp every 5 minutes) Plus you get air temp and average
water temp with profile (graphically).
