Scuba Forum / General / September 2004Navy tables or PADI tables - which is better?
Which dive tables are better to use, the U.S. Navy table, or PADI table? The USN tables seem more liberal on the front end (60 ft. for 60 min. vs. 60 ft for 50 min. for PADI), but seem more conservative than PADI for surface intervals and RNT. >Which dive tables are better to use, the U.S. Navy table, or PADI table? .. Depends on what you are using it for. For a combat diver under the control of a diving officer with an on-site decompression chamber available, us the Navy table. (There is a LOT in the way the Navy table are used that is not apparent from the tables themselves!) For a recreational diver, use the PADI/DSAT table.

My Navy tables give 60 ft. for 55 min, 75 min, 110 min, 150 min, 180 min, and 210 min.

In Denmark, the only table which are allowed for commercial divers are the Navy table. Martin > Which dive tables are better to use, the U.S. Navy table, or PADI > table? [quoted text clipped - 3 lines] > for > surface intervals and RNT. I've got a set of PADI Navy tables on a credit card sized card. 60' for 60 minute tables. This is what I was trained on. We were trained to add a safety factor into the tables - go to the next greater depth on the table (a 55' dive would be 70' on the table). I never did use the wheel. It looked like a PADI money making gimmick. I now dive with two computers, but still carry the Navy tables.
