How to Use This Calculator
- Enter your planned dive depth in meters.
- Set your intended bottom time in minutes.
- Indicate whether this is a repetitive dive and enter your surface interval in minutes if so.
- Read No-Decompression Limit (NDL) in minutes — do not exceed this without decompression training and equipment.
- Check whether a safety stop is recommended and at what depth (usually 5 m for 3 minutes).
- Review the Dive Risk Level (Low/Moderate/High/Critical) to assess how conservatively you are diving.
