Open 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 50m and is 10 mins into his dive.
The maximum depth he has reached on the dive is 50m
His first decompression stop is 2 minutes at 28m.
He is using Air and is diving on open circuit.
It will take him fourteen 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 14 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!”
