Dive Logs and Computers

Post by Robert Star » Mon, 11 Jan 1999 04:00:00


I just started using a dive computer not long ago and was wondering how
various people log the dives. My computer is not "downloadable" so I
have to amnually transfer the data to my log book. If I just transfer
all the info then translate that info for divetable use, the tables go
off the chart. I realize why this happens. But what do I put in my log?
Depth, max time? This isn't much info. any comments would help.

Robert,
        answer is easy.  I have the same, and still log all dives.  Mine holds the
last 5, I write them in when I get home.  I just remember approx. time at
max depth, if square profile write in pressure group.  If not (usually the
case) I log as ML computer.  Using surface intervals & dive times, I can
calculate the start / finish times quite easily...compare last SI to time,
subtract from there.  Remember, the best dive computer is between the ears.

Robert,

If you want more information about the dive for your log, you might
consider drawing out your approximate profile.  I did this on most of my
deeper dives, noting what time in the dive I reached max depth, and what
time was spent (approximately) at shallower depths and precautionary
stops.  After a couple dives you get pretty good at it.  The information
is really just for you, so you can do it all by memory, or take a slate
down and make some notes during the dive.  

Most of my dives are shallow, and I just record max depth and bottom
time.  

Having just bought a down-loadable computer, I can now say that they're
the way to go.

Jim

I use mine as a diary.  I write about what the place was like, other people,
etc.  As far as dive groups go, don't sweat it.  There are no log book
police out there.

What kind of computer do you have. It should be designed to help you
pre-plan your dive. Both of mine do that. You are computer diving not
table diving. This makes a big difference. Depending on the design
(table base vs. tissue base) the computer will give you more dive time &
shorter SI, however it also decreases the safety margins. Using tables
or computer you could still get DCS if you do everything right. Plan the
dive, record it in the log and then do your post dive recording after
you come up and compare if followed your plan. It is still a good idea
to do record all your planned and actual gas usage.
