Why dive Nitrox?
- 1. Safety - If used properly, Nitrox can add additional safety to your diving plan.
- 2. Stay down longer - Since you take in less nitrogen, the no decompression dive limits are extended and you will be able to stay down longer provided you have the air supply. See table below for an example of maximum time limits using different Oxygen mixtures.
- 3. Less tired at the end of a dive day - Some people have reported that they feel better and less fatigued at the end of a dive day.
