* What I mean by 'Basic Dive Planning'

If you have a couple pieces of basic data:
You already have enough information to do some predictive or estimated dive planning based on actual historical information. Given a planned tank size, gas fill pressure and maximum depth you can calculate things like:

Well What's a Diver to Do?

Cry. Just cry. You'll have to pick what is most important to you. Here is what I recommend:

If you have a dive computer...
...download and use Subsurface...you'll curse the gods for a while as the interface is just horrid, but you just need a place to save the raw dive data
If you do not have a dive computer...
...put your basic dive info in Excel (see "basic dive info" below)
If you are getting your Open Water with SSI...
...also use the SSI app until you get to Master Diver (~50 dives) and then stop using it. Not because it's a great dive log...it's because SSI makes it damn near impossible to get your various cards and awards unless you use their app.
