How to plan a decompression dive

When planning a decompression dive, select Deco as the dive type and follow the same steps as for a no-decompression dive when setting the surface interval and depth. In addition, you must define your planned bottom time. While adjusting the bottom time, the planner displays the corresponding no-decompression limit (NDL) and total time to surface (TTS) for that depth.

The decompression plan shows a detailed breakdown of your planned dive, including:

  • Type of Step: Descent, bottom, ascent, stop, or surface
  • Depth
  • Time to spend at each stop
  • Accumulated run time at the end of each step
  • Suggested gas for each segment
  • Gas switch recommendation, if required
  • Dive profile graph showing the depth curve and stop positions
  • Total run time: Total dive time including all decompression stops
  • Total decompression time required
  • NDL value at the maximum depth
