Best Nitrox Mix Table for every depth
Finding the optimal Nitrox mix for your planned dive depth maximizes your bottom time while staying within safe oxygen exposure limits. Each blend is calculated using the conservative PPO₂ of 1.4 bar.
What does 'best mix' mean?
The best nitrox mix is the blend that maximizes your bottom time at a specific depth. However, the actual best choice depends on factors like your specific dive profile, gas availability, and personal preference. Always consult a certified Nitrox instructor.
