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.
How long can you scuba dive at 100 feet?
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).
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.
Is 100 feet a deep dive?
Usually, a deep dive is considered to be a dive between 100 feet / 30 meters. On a deep dive your bottom time is limited because of nitrogen absorption, additionally air consumption increases at depth because of ambient pressure.
What happens if you dont decompress?
If they are not given enough time, or more bubbles are created than can be eliminated safely, the bubbles grow in size and number causing the symptoms and injuries of decompression sickness.
What is the no decompression limit or NDL?
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 you dive at 90 feet?
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. Of course, that is not to say that all divers will dive these profiles.
How long can you dive at 200 feet?
In technical diving, a dive deeper than 60 meters (200 feet) is described as a deep dive. However, as defined by most recreational diving agencies, a deep dive allows you to descend to 18 meters and beyond.
Should you accidentally exceed your dive computer’s no decompression?
If you exceed your no decompression limit (NDL) by less than 5 minutes when using the RDP you should: slowly ascend to 5 meters/15 feet and make an eight minute stop, then not dive for at least six hours. Any dive that your computer provides no decompression dive time for is acceptable.
What happens if a diver does not decompress?
If the pressure reduction is sufficient, excess gas may form bubbles, which may lead to decompression sickness, a possibly debilitating or life-threatening condition. It is essential that divers manage their decompression to avoid excessive bubble formation and decompression sickness.
