3.3.5. Ascent Rate Indicator
The ascent rate is shown graphically along the right side of the display as follows:
TABLE 3.2. ASCENT RATE INDICATOR
Ascent Rate | The equivalent | Example | |
Indicator | ascent speed | in Fig. | |
No segments | Below 4 m/min [13 ft/min] | 3.8 | |
One segment | 4 | - 6 m/min [13 – 20 ft/min] | 3.9 |
Two segments | 6 | - 8 m/min [20 – 26 ft/min] | 3.10 |
Three segments | 8 | - 10 m/min [26 – 33 ft/min] | 3.11 |
Four segments | 10 - 12 m/min [33 – 39 ft/min] | 3.12 | |
Four segments, the | Above 12 m/min [39 ft/min] or |
| |
SLOW segment, | continuously above |
| |
blinking depth reading, | 10 m/min [33 ft/min] | 3.13 | |
the STOP sign and |
|
|
|
an audible alarm |
|
|
|
When the maximum allowed ascent rate is exceeded, the fifth SLOW warning segment and the STOP sign appear and the depth reading starts to blink, indicating that the maximum ascent rate has been exceeded continuously or that the current ascent rate is significantly above the allowed rate.
Whenever the SLOW warning segment and the STOP sign appear (Fig. 3.13.), you should immediately slow down your ascent. When you reach the depth zone between 6 m to 3 m [20 ft to 10 ft] the STOP and CEILING depth labels will advise you to make a Mandatory Safety Stop. Wait until the warning disappears (Fig. 3.14.). You should not ascend shallower than 3 m [10 ft] with the Mandatory Safety Stop warning on.
WARNING!
DO NOT EXCEED THE MAXIMUM ASCENT RATE! Rapid ascents increase the risk of injury. You should always make the Mandatory and Recommended Safety Stops after you have exceeded the maximum recommended ascent rate. If this Mandatory Safety Stop is not com- pleted the decompression model will penalize your next dive(s).
