How do you read a US Navy dive table?
Depth: For the US Navy Dive Tables depths are measured in feet of salt water. Depths are listed down the far left side of the table. When planning a dive, always round to the next deepest depth.
At what depth do you need decompression stops?
15-20 feet
Because they are known to reduce the risk of decompression sickness (DCS), safety stops should be considered standard procedure for all dives below 33 feet (10 m); they should not be considered optional. The depth most commonly associated with the term safety stop is 15-20 feet (5-6 m).
How many decompression dives can you do in a day?
The number of dives you can do per day depends on the depth and length of each dive. For recreational divers, a typical limit is 4-5 dives per day as long as you follow dive tables or use a computer to track.
What happens if you exceed no decompression limit?
If a no-decompression limit is exceeded by 5 minutes or less, make an 8-minute stop at 15 feet and remain out of the water for 6 hours before diving again.
What happens if you exceed no-decompression limit?
What depth does the bends start?
The Bends/DCS in very simple terms Anyone who dives deeper than 10 metres (30ft.) while breathing air from a scuba tank is affecting the balance of gases inside the tissues of their body. The deeper you dive, the greater the effect.
What is a no deco dive?
No-decompression dives A “no-decompression”, or “no-stop” dive is a dive that needs no decompression stops during the ascent according to the chosen algorithm or tables, and relies on a controlled ascent rate for the elimination of excess inert gases.

What happened to the US Navy decompression tables?
The US Navy decompression tables have been revised and republished. On the 1st of April 2017, Revision 6 of the USN Tables was replaced by Revision 7.
Can I use the same decompression table on a second dive?
If you decide to go on a second dive the decompression table you just learned to use would not be accurate. Because you would be starting with excess nitrogen, it would be very possible to get decompression sickness even if you followed the decompression table as was done on the first dive!
What decompression table should I use for this lesson?
Please use the US Navy Decompression Table for this lesson. In the future it will be easy to switch to any other such as the PADI Recreational Dive Planner. This is a photo of the table we will be using. Let’s begin. Look at the upper left of the table. It should look like the following photo:
What is the maximum depth you can decompress a ship?
A zero is found under the 10′ decompression stop column. The US Navy is telling you that you should not spend more than 200 minutes at 40′ if you do not want a ceiling. Look at 50′ for 100 minutes. That is also a limit for that depth.
