DEEP STOP PREVIEW
If Deep Stop was set to ON in the UTIL Menu, the Deep Stop preview screen is available after exceeding 24 m
(80 ft) of depth. The Deep Stop is always at a depth half that of your maximum depth during the dive. This preview
screen keeps track of that depth for you.

DEEP STOP MAIN
If triggered, the Deep Stop will activate upon ascending to within 3 m (10 ft) below the calculated Deep Stop
depth. The stop time will be displayed and count down to 0 min :00 sec as long as you stay within 3 m (10 ft)
above or below the stop. While Deep Stop Main is displayed, you may access up to 3 ALT displays by pressing
the ADV button to cycle through them. They are similar to the No Decompression Main, Dive ALT 1, and Dive ALT
2 displays, respectively. See Deep Stop in the Dive Features chapter for further details.
NOTE: The i550C does not penalize for a missed Deep Stop.
