Nitrox Calculator: NDL, MOD and PpO2 Limits (EANx)
Nitrox (EANx) is any breathing gas with more than 21% oxygen. Raising the oxygen fraction lowers nitrogen, extending your No-Decompression Limit (NDL) but reducing your Maximum Operating Depth (MOD) because of oxygen toxicity. At 30 m, EAN32 nearly doubles bottom time versus air while capping MOD at 33 m.

Work out your bottom time and depth cap here. Depthlog logs the real dive when you get back: the mix, the depth, and how your EANx exposure adds up over the trip.
This tool is intended to be used as an informational and educational tool
Always check the safety regulations and follow the standards relating to repetitive diving. Consult a certified diving instructor for proper training. Read the dive safety disclaimer and the Terms of Service.
