  • Ascent rate

Ascent rate

The ascent rate is displayed as a vertical bar along the right side of the display.

ascent rate Dseries

When the maximum allowed ascent rate is exceeded, the lower segment of the bar starts to blink and the top segment stays solid.

ascent rate alert Dseries

Continuous ascent rate violations result in mandatory safety stops. See Safety stops and deepstops .

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 if you have exceeded the maximum recommended ascent rate. If the mandatory safety stop is not completed, the decompression algorithm penalizes your next dive(s).
