ATR (AIR TIME REMAINING)
ATR is the time you can remain at your present depth and still safely surface with the tank pressure reserve that you selected during setup (the End
Pressure Alarm setting).
The Sage calculates ATR using a patented algorithm that is based on a diver's individual air consumption rate and current depth. Tank Pressure is
measured once each second and an average rate of consumption is calculated over a 60 second period. This rate of consumption is then used in
conjunction with a knowledge of the depth dependence to predict the air required for the diver to make a safe controlled ascent including any Stops.
Air consumption and depth are continuously monitored and ATR reflects any change in circumstances. For example, when you suddenly find your-
self swimming against a strong current and begin breathing more rapidly, the Sage will recognize the change and adjust the ATR accordingly.
ATR Safe Minutes will display on the Dive Main screen when it is the controlling factor of dive time. ATR Safe Minutes can be found on the ALT 1
screen when ATR is not the cntrolling factor of a dive.

BAR GRAPHS
The Sage features two specific bar graphs.
1. The one in the center represents ascent rate. It is referred to as the Ascent Bar Graph.
2. The one on the right represents nitrogen loading. It is referred to as the N2 Bar Graph.

ASC BAR GRAPH
The Ascent Bar Graph provides a visual representation of ascent speed (i.e., an ascent speedometer). When the ascent is faster than the
recommended 30 fpm (9 mpm), all segments flash until the ascent is slowed.

FPM (MPM)
0 0 - 5 (0 – 1.5)
1 >5 - 10 (>1.5 - 3.0)
2 >10 - 15 (>3.0 - 4.6)
3 >15 - 20 (>4.6 - 6.1)
4 >20 - 25 (>6.1 - 7.6)
5 >25 - 30 (>7.6 - 9.1)
6 >30 (>9.1)
N2 BAR GRAPH
The N2 Bar Graph represents your relative No Decompression or Decompression status. As your depth and elapsed dive time increase,
the bar graph will grow in length, shift from green to amber, and ultimately to red (indicating a Decompression condition). As you ascend
the bar graph recedes, indicating that additional No Decompression time is available. The Sage monitors multiple theoretical nitrogen
compartments simultaneously. The N2 Bar Graph displays the one that is in control of your dive at any given time.
