Do you dread the table portion of classes?

I bought the dive computer, pushed a few buttons. Voila!!! Magic.

This all changes when you get into decompression / technical diving. There are no buttons to push when your computer craps out and your stuck with a timing device and your tables

And when that computer battery dies on the 4th dive of the 2nd day of your week long diving trip in bonaire what do you do?

I loved learning the tables. It was my favorite part and I still use them to this day.

The only one I thought was a PITA was the wheel, utterly useless AFAIC.

Been there, done that, learned the lesson. I just go to my backup.

If you don't understand the math/tables you don't understand what is behind the button. Recreational maybe ok, technical dive not a good thing... I haven't seen any rec divers with two computers.

You know you've used the tables one time too many when you're sitting at a dive club meeting and the presentation is on emergency procedures and they tell you a diver has just gotten back on the boat after the first dive of the day and collapses and his buddy says they were at 50 feet for 45 minutes and they had no problems at all and you immediately think to yourself "Ah, gee."

Huh? 50 feet for 45 minutes shouldn't be an issue....not on air, certainly not on EAN....unless they decided to rocket to the surface. What am I missing here???

You beat me to it. Apparently the poster in question doesn't have his tables memorized as well as he thought

That's what I thought too. We'll see. I'm doing the PADI course. They teach the calcs too. It's not difficult stuff, but then again I've never strayed far from math in my daily life. I can understand how someone that has not picked up a math book in a few years could have some trouble with the calcs.

Should have looked into the e-learning...

Well since you are confident with the RDP why not stick with it, use EAN32, and knock 20% off your depth and be done.

Yep. Per PADI's RDP, that would br group O and the NDL is 80 min. On air.

I just LOVE my iPhone dive planner.
