Does nitrox allow you to dive longer?
Longer Dive Times
But absorbing less nitrogen on your first dive with nitrox gives you more repetitive dive times. You’ll also get around five more minutes at 70 feet when you use the gas. It may not seem like much, but those extra five minutes can be precious, depending on your dive.
Is it better to dive with nitrox?
Nitrox proves to be especially useful for divers, who want to perform more than one dive per day. Due to having absorbed less nitrogen on the first dive, Nitrox divers will have a longer allowable bottom time on a repetitive dive.
Can I dive with air and nitrox in the same day?
You can dive Nitrox and air, or different Nitrox mixes in one day. Most Nitrox classes will provide you with equivellant air tables for different mixes of Nitrox anyway.
Does nitrous last longer than air?
2. Extended Bottom Time. Recreational Nitrox which may contain anything between 21 and 40 percent of oxygen, has a lower percentage of nitrogen than air. … Diving with Nitrox enables you to remain for about 42 minutes at the same depth, keeping in mind your air-consumption.
Is nitrox safer than air?
Nitrox refers to any gas mixture composed (excepting trace gases) of nitrogen and oxygen. … Nitrox is not a safer gas than compressed air in all respects; although its use can reduce the risk of decompression sickness, it increases the risk of oxygen toxicity and fire.
How much longer can you stay underwater with nitrox?
Based on the Recreational Dive Planner, for example, a diver on air at 100 feet reaches his or her no-decompression after 20 minutes. At 60 feet, the diver’s maximum time would be 55 minutes.
How deep you can dive with nitrox?
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.
Does nitrox improve air consumption?
Misconception #1) Your air consumption will improve if you dive with nitrox. … However, a higher percentage of O2 allows you to stay at a safe depth longer than someone diving on air before having to proceed to a shallower depth due to no decompression times.
How deep can rebreathers go?
Somewhat differently from the more technically oriented dive-training agencies, PADI offers two levels of recreational rebreather diver course, qualifying students to a maximum depth of 59 feet (18 m) and 130 feet (40 m) respectively.
What is the no decompression limit?
The no decompression limit (NDL) is the maximum allowable dive time that you can remain at a specific depth and ascend directly to the surface without requiring staged decompression stops on the way up. Remember the higher the partial pressure of nitrogen (ppN2), the shorter the dive time (NDL).
How do you calculate nitrox?
Calculations in feet
The equivalent air depth can be calculated for depths in feet as follows: EAD = (Depth + 33) × Fraction of N2 / 0.79 − 33. Working the earlier example, for a nitrox mix containing 64% nitrogen (EAN36) being used at 90 feet, the EAD is: EAD = (90 + 33) × 0.64 / 0.79 − 33.
What are two equipment items that do not need to be cleaned for oxygen service?
What are two equipment items that do not need to be cleaned for oxygen service? Equipment that is exposed to low pressure oxygen, such as buoyancy compensators and their low pressure inflators and dry suit inflation valves do not need to be cleaned or lubricated for oxygen service.
