THE BOTTOM ROW
The bottom row displays the current mode, gas and decompression information (Fig. 4.28).
Circuit Mode
The current breathing configuration. One of:
OC = Open circuit, bailout so it displays in Yellow (Fig. 4.29). CC = Closed circuit (Fig. 4.30).
The current gas shown as a percentage of Oxygen and Helium (Fig. 4.31).
The remainder of the gas is assumed to be Nitrogen.

CC

O2/HE
21/OO
Fig. 4.31
In closed circuit mode, this gas is the diluent. In open circuit mode this is
the breathing gas.
It displays in Yellow when there is better deco gas available than the current gas (Fig. 4.32).
No Decompression Limit (NDL)
O2/HE
21/OO
Fig. 4.32
NDL
2O
The time remaining, in minutes, at the current depth until decompression
stops will be necessary (Fig. 4.33). Displays in Yellow when the NDL is
less than 5 minutes (Fig. 4.34).
Fig. 4.33
Once NDL reaches 0 (i.e. deco stops needed), the NDL display is just
wasting space. To address this, a few different values can be set to replace
the NDL (see Dive Setup → NDL Display).

The options are:
Fig. 4.35
CEIL: The current ceiling in the current units (feet or meters) (Fig. 4.35).
Flashes Red if you ascend shallower than the current ceiling.

CEIL

GF99
8O%
Fig. 4.36
GF99: The raw percentage of the Bühlmann allowable supersaturation at
the current depth (Fig. 4.36).
@+5: The predicted time-to-surface (TTS) if you were to stay at the current
depth for 5 more minutes (Fig. 4.37).
