In Reply to: in the Navy we had to memorize deco tables posted by CalAbDiver on July 18, 2001 at 13:46:46:
60=60 [60 mins at 60 ft, easy to remember]
70=50 mins [increments of 10]
100=25 mins [increment moves to 5s now]
200 is a deco dive, but the deco stop is like what we would call today a safety stop, 3 mins at 10 feet. the USN tables go to 300 fsw.
from here on down, deeper, every minute you spend at depth has to be given back in deco and there are no NDLs.
the USN protocol will probably bend everybody here into DCS. rep dives are unusual to these depths and not recommended.
the general rule for using the USN tables is:
always go into the table at the next deeper depth;
always use the next longer time;
PADI tables are about 25% more conservative than USN.
