Deep Stop Main; Safety Stop Main; Surfacing - Aqua Lung i450T Owner's Manual

DEEP STOP MAIN

If triggered, the Deep Stop will activate upon ascending to within 10 ft (3 m) below the calculated Deep Stop
depth. The stop time will be displayed and count down to 0 min as long as you stay within 10 ft (3 m) above or be-
low the stop. While Deep Stop Main is displayed, you may access up to 3 ALT displays by pressing the ADV but-
ton 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 i450T does not penalize for a missed Deep Stop.

SAFETY STOP MAIN

If triggered, the Safety Stop will activate upon ascent to within 5 ft (1.5 m) deeper than the Safety Stop depth on a
No Deco dive. The stop time will then countdown to 0 min. While Safety Stop Main is displayed, you may access
up to 3 ALT displays by pressing the ADV button repeatedly. They are similar to the No Deco Main, Dive ALT 1,
and Dive ALT 2 displays, respectively. See Safety Stop in the Dive Features chapter for further details.
NOTE: The i450T does not penalize for a missed Safety Stop.

SURFACING

Upon ascending to 3 ft (0.9 m) the i450T transitions to Dive Surface mode.
NOTE: The i450T requires a 10 minute surface interval to record a subsequent dive as a separate dive
in the Log. Otherwise, the dives will be combined and recorded as a single dive in the i450T memory.
