Closed Circuit Diver – Decompression Screen
This dive screen shows
The diver has a decompression burden – hence the yellow colour on the right of the
screen.
The diver is at 42m and is 56 minutes into his dive.
The maximum depth he has reached on the dive is 42m
His first decompression stop is 1 minute at 12m.
He is using Trimix 15/45 and is diving on closed circuit.
The computer is planning decompression based on the internal setpoint.
The internal PO2 setpoint is 1.40.
An external link to the rebreather is not connected or has not been activated.
It will take him nine minutes to reach the surface at an ascent rate of 10m per minute
and including required decompression stops. In other words his Time To Surface
(TTS) is 9 minutes.
The dark colour on the graph shows the track of the dive so far. The light colour
shows a profile of the ascent the diver should make if he ascends now.
Note that in the Display Modes Screen the diver has ticked Deco, MaxD and tts.
Note too that when in deco the top line of the right side of the screen will alternate
between “MaxD” and “deco!”
