Dive tables are important for how long you can stay down. Your body<br />
absorbs nitrogen when breathing from a tank at different depths <strong>and</strong><br />
the tables help you stay within safe levels.<br />
There are letters on the card to tell you what type of diver you are. The<br />
numbers tell you how deep, how long you were down, or how long<br />
you were up. This is important for your safety.<br />
If you are going down 80 feet for 30 minutes you would be a G diver<br />
on the dive tables. Then you would go to the second table <strong>and</strong> see how<br />
much time you are going to spend on l<strong>and</strong> or boat. If you stay up for 1<br />
hour <strong>and</strong> 20 minutes you would then be a E diver. If you wanted your<br />
second dive to be 40 feet your residual nitrogen time is 49 minutes<br />
<strong>and</strong> your no decompression limit is 81 minutes. Which means that you<br />
should stay in the limit of 81 minutes at 40 feet to stay safe. Knowing<br />
dive tables is how math is involved with diving.
