The tables work just fine... Very true.
So that means your calculator or the computer on your desk is just another tool in your tool box. I'm not sure I can remember the last time I pulled out the yellow pad and No2 pencil to figure a percentage but because of what I was taught during school some simple percentages can be done in my head.
I sure do
Just as you don't NEED a calculator every time you figure certain math, You don't NEED a computer to do certain dives.
Do I think it is a tool to make things eaiser, hell yes, but do I NEED either a calculator or a dive computer No..At least not in the same sense that I NEED a tank with air in it
