How to plan a dive using the Dive planner

How to plan a dive using the Dive planner

Before planning your first dive, go through the planner settings and configure them according to your personal preference. Access the planner and adjust settings under Main menu » Dive planner.

  1. First set the values for:

    • personal gas consumption (default value: 25 L/min / 0.90 ft3)
    • tank pressure (default value: 200 bar / 3000 psi)
    • tank size (default value: 12 liters / 80 ft3, 3000 psi)
    NOTE:

    It is important to adjust these values first to get the gas calcualtions right.

  2. Use the lower or upper buttons to decrease or increase the values. If you are not sure what your personal gas consumption is, we recommend using the default value of 25 L/min (0.90 ft3/min).

    NOTE:

    Estimated gas time is calculated based on tank pressure at start minus 35 bar (510 psi).

    In View planner you can see the calculated plan for your dive.

The calculated no decompression time is based on dive depth and gas mixture. Any residual nitrogen from previous dives, as well as surface time, is taken into consideration. Gas time is dependent on the dive depth, personal consumption and tank size/pressure.

Planning the first dive in a series

  1. Edit depth and mixture in View planner.
  2. As an example, enter 18 meters, use a mixture of 21% oxygen, and you will see the following:

    In this example, the calculated values are:

    1. Dive number in the dive series: 1
    2. Available no decompression time: 51 minutes
    3. Remaining gas time: 41 minutes

Planning additonal dives

  1. The dive planner allows you to adjust surface time in 10-minute increments. 48:00 hours is the maximum value to be set.

    In the example below, the surface time before the second dive is 1:37 minutes. Adjust surface time to see how it impacts no decompression time.
