The 8 triangular segments of the bar graph, located beside green, yellow, and
red reference zones, appear beginning from the bottom and may be considered
an ascent rate speedometer. Green is a 'normal' rate, yellow is a 'caution' rate,
and red is 'Too Fast'. The actual speeds that the VARI segments represent are
shown at the left.
When your ascent rate exceeds the maximum recommended rate of 60 feet (18
meters) per minute, the bar graph segments will enter the red zone and all dis-
played segments will flash once per second until your ascent speed is slowed.
When this occurs, you should immediately slow your ascent.
The Variable Ascent Rate Indicator is a unique feature of Oceanic dive com-
puters that has been granted U.S. Patent No. 5,156,055.
Breathing Gas Consumption Indicator
The Breathing Gas Consumption Indicator bar graph located at the lower/left
portion of the display (Fig. 10) is a true biofeedback monitor that indicates
your current breathing rate as compared to your personally established
breathing parameters. The comparison is based upon an average rate estab-
lished during the first 70 seconds of breathing that is sensed.
After the comparison, the bar graph will provide you with continuous visual
indication of your breathing rate as it slows or increases. Use of Oceanic's pat-

VARI Segments = Speed (rate)
0 = 0 - 10 fpm (0 - 3 mpm)
1 = 11 - 20 fpm (3 - 6 mpm)
2 = 21 - 30 fpm (6 - 9 mpm)
3 = 31 - 40 fpm (9 - 12 mpm)
4 = 41 - 50 fpm (12 - 15 mpm)
5 = 51 - 60 fpm (15 - 18 mpm)
6 = 61 - 90 fpm (18 - 27 mpm)
7 = 91 - 120 fpm (27 - 36 mpm)
8 = >120 fpm (>36 mpm)
