Do you need to decompress at 30 feet?
The deeper and longer your dive the more chance you need decompression stops. Shallow dives of 6-10 metres (20-30 feet) you can spend over 200 minutes without a decompression stop. Dives to over 30 metres (100 feet) limit your dive time to around 20 minutes before a decompression stop is required.
Can you dive deeper with nitrox?
So how deep can you dive with nitrox? With 32% nitrox you can dive to a maximum depth of 33 metres (110 feet). Whereas with 36% nitrox this reduces to 28 metres (90 feet). Nitrox extends your dive time and in some cases is nearly double that of atmospheric air at the maximum dive depths for nitrox.
At what depth is nitrox toxic?
However, when diving on nitrox, the potential for oxygen toxicity lurks well within the depth range of recreational diving: the maximum depth on 32 percent nitrox is 121 feet; on 36 percent nitrox, it’s just over 100 feet. Many divers regularly cruise at these depths and even deeper without giving it a second thought.
Is nitrox better than air?
Nitrox allows you to spend more time at depth compared to diving on air, which means you’ll get a lot more out of your diving holiday. Even if you’re only making one dive, but it’s deeper than 15 metres/50 feet, nitrox is beneficial.
What is the deepest dive ever made?
The deepest dive on record is 1,082 feet (332 meters) set by Ahmed Gabr in 2014. That depth is the equivalent to approximately 10 NBA basketball courts aligned vertically. In terms of pressure, that’s about 485 pounds per square inch. Most people’s lungs would be crushed at that depth.
At what depth does oxygen become toxic?
Oxygen toxicity occurs in most people when the partial pressure of oxygen reaches 1.4 atmospheres or greater, equivalent to slightly over 187 feet (57 meters) depth when breathing air (shallower depths when breathing oxygen concentrations greater than 20%).
Can I dive nitrox without certification?
Though the benefits of EANx are myriad, we thoroughly recommend getting at least your Advanced Open Water before you start thinking about nitrox certifications. To dive with nitrox, you absolutely need to be certified. As with all types of scuba diving, without sufficient training, it can be incredibly dangerous.
How much does nitrox certification cost?
You can register online by paying the $25.00 registration fee. Your instructor will collect the remaining fees in person. The PADI Enriched Air – Nitrox (EANx) SCUBA Specialty Course is a one-evening class.
