[PSUBS-MAILIST] DSV Aquatic update

[Cliff Redus via Personal_Submersibles]

I see depth on your navigation HMI but not altitude.  Are you planning on
adding this sensor?  Having run my boat for several years, I find that all
data is not equally important.  What I find I check a lot are SOF of air
tanks, SOC of batteries, depth, altitude, O2 and CO2 levels, and compass
heading.  Other parameters I check less frequently.  Also you use an
aircraft roll, pitch and compass heading style indictor which looks very
nice.  Having said that, my experience is that K boats have a large spread
between CB and CG.  As such my guess is that your indicator will not show
much variation in pitch or roll under normal operating conditions but of
course your heading will be active.

Keep updates coming.  I enjoyed video.  Would be nice to have voice over as
you walk through buttons and screens on HMI.

Best Regards

Cliff
