What happens when your computer dies and you don't know the tables? Divings over for that trip, huh.
I've been at the lake when an SDI diver was on his third dive, but he couldn't afford to rent a computer and didn't know the tables. We stopped to explain them to him, so he wouldn't get hurt.
The option of not learning the dive tables and trusting your computer is tantamount to two divers using the same computer. If one buddy is using tables, then you should always go with the most conservative procedure. DCS is not a cold that goes away, it's a serious malady that is life and limb threatening.
I won't dive, or fill tanks for anyone that doesn't know/understand the dive tables. If they want a fill, they take a refresher from an agency that teaches tables first.
