As a beginner, I am a little overwhelmed. I have 6 dives under my belt. I am reading the book, but it seems llike there is so much info! I like my dive tables better haha JK.
I have read that a dive computer is only as good as the information you know to get from it.

So for the pros here. I'm going to the Blue Grotto this weekend to basically test and play with the computer. I am nitrox certified and will be diving nitrox this weekend.
Are there a few features that I should focus on to help me learn? Or should I bust my balls to learn as much as possible?
Maybe this is a stupid question, but I'd like to get your feedback. Everyone here as been so kind with my newbie questions.
