I concur. All of these suggestions above sounds good to me, and while we
discuss the future of dive-planning i would like to add some of my
Currently i use GUE Deco planner for my planning. Its kind if clumsy on
some parts but its great on others. Its quite old but it runs great
under wine =)
One feature i just love is how easy it is to define eg. a standard set
of deco gases and try and run the numbers with them. For example when
you are planning a dive and you are trying to figure out of you should
do the dive with only 100%, only 50% or both. Its dead simple to just
flip between them and look at the numbers and see if it looks like a
better dive plan.
Another thing i love is the way to define your standard bottles. I
almost aways dive my D12-232's so having the dive planner calculate your
gas consumption and show you how much of your planned gas supply you
would have consumed at different parts of the dive would be great. This
would be fantastic if it could for ex. show you where under a dive your
first stage would run out if you do a staged dive.
