So, that’s about it! If necessary, you may do a direct ascent to the surface at a rate of 60 fpm from any dive that is within the table NDLs. That’s what NDL means: No Decompression Limit! But you will gain significant benefit from an ascent rate of 30 fpm and a 3 minute safety stop at 15 feet.

What is the no decompression limit for 60 feet?

56 minutes
What is the No Decompression Limit for 60 feet? The NDL or No-Stop time for 60 feet / 18 meters is 56 minutes according to the Recreational Dive Planner table.

What should you do if you exceed your no decompression limit?

If a no-decompression limit is exceeded by more than 5 minutes, make at least a 15-minute stop at 15 feet and remain out of the water for a minimum of 24 hours before diving again.

How deep can you go without decompressing?

There’s a bit of physics and physiology involved in a full explanation, but the short answer is: 40 metres/130 feet is the deepest you can dive without having to perform decompression stops on your way back to the surface.

Should you accidentally exceed your dive computer’s no decompression limit SDI?

Activities that may increase the risk of decompression sickness include: Should you accidentally exceed your dive computer’s no-decompression limit. Air permitting, make the decompression stop indicated by your dive computer. Afterward, monitor for signs and symptoms of decompression sickness.

How long can you dive at 60 ft?

A not uncommon 2 tank dive trip might be the first dive at a max of 90 feet with a max time underwater of 35 minutes while the second dive might have a profile of max depth of 60 feet with a max time underwater of 50 minutes.

How do you do a decompression stop?

The ideal way to make a good decompression stop is to stay in the horizontal position for as long as possible. In this position, your body slows down the water column and helps you stay at the right depth. The extended position also allows the entire body to be subjected to the same pressure.

How do you calculate decompression stops?

Usually newer dive computers incorporate Deep Stops into their algorithms, and alerts divers when to take a Deep stop. However for those recreational divers wanting to manually calculate when to take one, simply divide your max depth by two and do a 30 second to a minute stop there.

What is the NDL for a dive to 20 feet?
