cuberoot3i:know the tables, dive with a computer. this will extend your bottom time. if you go "tec" you will dive tables with a computer as a back up.
if you need help with a computer ask. most accadents happen by not being able to understand what you see. i would recommend staying away from most info on gue and the "dir" stuff untill you had some experance. it deals with caves and egos.
Cuberoot, I veiw dive tables and dive computers both as teaching tools. Ultimately you really do not need either. For air, you can sum to a factor of 115, where the number 115 is the sum of your depth in feet and your bottom time in minutes (including descent). That gives you quite good NDL limits for air.
There are similar factors for EAN32 and EAN36, and you can even calculate your own based on equivalent air depths. Now you would not need either a computer nor a table with NDLs on it with you, while you were diving. Nor would you need to memorize tables (like many of us did when we all got started).
A software program for planning your residual dives would work even better, since you could program customized conservatism factors into it as well. But that is a tech issue.
Tech is beyond the scope of the original question however.
