How long can you dive at 30 feet?

Interesting question Spoon. Well strictly speaking they are time limits i.e (NDL limits) on dives to 12 meters (30 feet) however you’d need to be in the water for close to 4 hours on the first dive for this to be an issue.

How deep can you dive without decompression stop?

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.

What is the no decompression time?

The “no-decompression limit” (NDL) or “no-stop limit” , is the time interval that a diver may theoretically spend at a given depth without having to perform any decompression stops while surfacing.

How long can a diver stay down at 35 ft?

205 minutes
Nitrogen is absorbed more readily at deeper depths, making how long can you SCUBA dive dependent on how deep you are. For instance, the time you can spend SCUBA diving at 100 feet is 20 minutes whereas if you limit your dive depth to 35 feet, you could stay for 205 minutes (if you had enough air).

Can you get the bends from 30 feet?

While sometimes there may be predisposing medical factors such as patent foramen ovale, divers must still treat shallow dives with as much care and respect as any other dive. If you’re one of those divers who was taught that “you can’t get bent shallower than 30 feet,” it’s time to revise the theory.

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 is the no-decompression limit for a dive to 20 feet?

No Decompression Limits (NDL)

Depth	Pressure	Oxygen (\%)
10 m/33 ft.	2 bar/ata	21\%
20 m/66 ft.	3 bar/ata	21\%
30 m/99 ft.	4 bar/ata	21\%
40 m/132 ft.	5 bar/ata	21\%
