Suunto EON Steel
If you ignore the alarm and stay above the safe margin for three minutes, Suunto EON
Steel locks the algorithm calculation, and decompression information will not be available
anymore on the dive. See 4.2. Algorithm lock.
Decompression display examples
Below is a typical decompression dive view showing ascent time and the first required
deepstop at 20.3 meters:
Suunto EON Steel shows the ceiling value always from the deepest of these stops. Deepstop
and safety stop ceilings are always at constant depth when you are at the stop. Safety stop
and decompression stop times are counted down in minutes, deep stop time is shown in
minutes and seconds.
In the below display, the ceiling depth is set to 10.8 m and the diver is currently at 11.1 m. White
arrows beside the depth value show the diver is inside the decompression window. 1' 18 is
shown in yellow as the time for an optional stop:
The below display shows that the ceiling depth is set to 3.0 m and the diver is at 3.7 m. The
white arrows indicate again that the diver is inside the decompression window. 3' 09 is shown
in red as the time for a compulsory stop:
The next example shows that the diver is at 2.4 m (ceiling depth is still set to 3.0 m), so inside
the decompression window but above the limit. A yellow downward pointing arrow indicates
the diver is recommended to descend to be at optimal depth. The optimal depth (the ceiling
depth) of 3.0 m is displayed in yellow:
The below display shows that the ceiling depth is set to 3.0 m and the diver is at 2.3 m. The
diver is outside of the decompression window and must descend. A red arrow and an alarm
sound prompt the diver to dive deeper and the ceiling depth is indicated in red. Instead of the
time, "- -" is displayed as the diver is outside of the decompression window.
