Section 2: Diving with the Monitor 3 Air
Ascent Rate
The optimal ascent rate varies between 23 and 67 ft/min. depending on the depth. Ascent rate is displayed as a percentage of the allowable ascent rate (rounded to the nearest 10 %). For example, if the allowable ascent rate at the current depth is 67 ft/min, and you ascend at 33 ft/ min, the ascent rate will display 50%. If you ascend at 67 ft/min the ascent rate will show 100%.
WARNING: The prescribed ascent rate must be observed at all times! Exceeding the prescribed ascent rate can lead to microbubble formation which can lead to serious injury or death due to decompression sickness.
If the ascent rate is 100% or more, the arrow appears. If the ascent rate exceeds 140%, the arrow starts flashing. Also, an acoustic alarm sounds when ascent rate is 110% or greater. The intensity of the alarm increases as the percentage over the allowable rate increases. Below is a summary of the ascent warnings.
