Congrats on the sweet new dive computer. Only like 4 scuba bucks or so??
I have to agree, you should read the manual a few times and you should start to understand what is going on. Then when you are ready to actually use the computer, plan your dive according to the tables and follow that plan while you look at your computer to try to understand how it is working. That way you are safe and within your no-deco limits until you know that computer.
From what I have read, it is a very good dive computer and lots of folks rave about them.
I am thinking about a new computer as well.
