3.3. Altitude diving
The atmospheric pressure is lower at high altitudes than at sea level. After traveling to a
higher altitude, you will have additional nitrogen in your body, compared to the equilibrium
situation at the original altitude. This 'additional' nitrogen is released gradually over time and
equilibrium is restored. It is recommended that you acclimatize to a new altitude by waiting at
least three hours before making a dive.
3.4. Ascent rate
The ascent rate is displayed as a vertical bar along the right side of the display. The higher the
bar, the faster you are ascending.
