just don't think most people can be bothered!  

if you have tables, a timer and your tissue code written down on every dive, then you are absoloutely sorted if your computer breaks.

if you are going to bother to do that, though, perhaps it would be easier to just write your planned depth, time and stops on your slate (which you can get from your computer, assuming it has a dive plan function). that way you're sorted if your computer breaks without messing around with tables. obviously it means that you can't deviate from your plan, but if your computer fails you're on your way up anyway, right? and the advantage is that you're not trying to use tables at depth (perhaps not easy with nitrogen loading) - instead you're just looking at a number.

<font color='#000080'>I use both a computer and a set of tables. I make a note of the no stop times verses depths on my slate so that if my puter dies I have a backup. I also make paper logs of my dives in a log book.

I use the tables to tell me my tissue code post dive and to plan what options I have for my second dive. I use the computer for accurate depth, dive time and no-stop dive time, as at the moment I'm not diving into stop dive times. I back this up with a watch but have to admit to not always looking at the start and finish times on my watch. (Perhaps my computer looks after my time lazyness). I know for some this sounds excessive as people use either a set of tables or a computer. But as a senior diver in my club recently said &quot;people seem to move from tables to computers and just trust them, without looking at the differences between what the Computer and Tables will allow them to do&quot;. Yes Tables are supposed to be safe because they assume a square profile (which is conservative) but Computers are also supposed to be safe as they allow for dynamic depths.

I don't know how many divers looking to buy a computer rate the different models available by conservatism? I know it was not something that was high on my list of priorities when I bought my computer.

I suppose looking at how I record my dives I will be able to look back in the future and cross check what the differences between tables and my computer are.

At the moment, as I'm quite new to diving and I find dive planning and recording the dive in a log all part of the dive experience.

I currently use a Suunto Vyper and BSAC tables.

Suppose everyone has to ask themselves this question.

Do you do Computer Controlled Diving? or
Do you do Computer &quot;Assisted&quot; Diving?

Agree a dive timer and a slate showing RDP Tablesetc etc should be a back up.
