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.
First set the values for:
It is important to adjust these values first to get the gas calculations right.
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).
Estimated gas time is calculated based on tank pressure at start minus 35 bar (510 psi).
You can adjust dive depth, dive gas O2 percentage and surface time interval.
Based on these parameters Dive planner shows no decompression dive time for your planning purposes. If tank size, tank pressure and gas consumption are filled, planner shows dive time calculation too.
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.
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:
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.
