I think the thing to focus on is the LCD display. Make sure
you understand what each area of the display is indicating.
Understand what makes it beep and how to resolve the warnings.
There are tons of fancy modes and alarms that you don't have to
use initially.
The good thing about the Versa Pro is that it will pretty much
"just works" out of the box with factory defaults.
It will even turn itself on when you jump in the water if you
forget to turn it on.
There is no "off" button. It will turn itself off.
For dive planning make sure you understand how to access the dive log.
You will need this information for planning future dives if
you are using tables.
If you want to plan based on the computer calculations rather
than tables you'll want to understand the dive plan mode.
If you want to play with it and don't have time to jump
in Larry's pool. There is a simulation/demo mode that will
allow you to simulate dives so you can see what the LCD
display will look like and what actual dive data looks like.
There are some funky things that seem a bit quirky
(at least to me)
- during the first 10 minutes after you surface certain things
work differently.
- dives start/end at about 3 to 4 feet.
So on an ascent, the dive will end before you are actually at the
surface and the display changes.
- If you are on the surface and it "thinks" it is not dark enough,
it will not turn the light on when you push the button.
Although it seems pretty intimidating, once you play with it a bit,
its not too bad.
Oh, and I'd make sure to take the manual on the trip just
in case you need to look up something.
The cheat card didn't seem too helpful to me.
