The surface interval must be at least 5 minutes for a dive to be considered a repetitive dive. Otherwise, it is considered a continuation of the same dive. The dive number will not change and the dive time will continue, where it left off (see also section 3.6.2. “Dive Numbering”).
3.1.4. User Definable Functions and Alarms
This Vytec has several User Definable Functions and depth and time related alarms that you can set according to your personal preference.
The dive computer model, unit of measurement and backlight prefer- ences can be set in the MODE- SET- SET PREF submode. The dive time and the depth alarms can be set in the MODE- SET- SET DIVE submode and the alarm clock can be set in the MODE- SET- SET TIME submode. Setting of the user definable functions and alarms are explained in detail in section 4.3. “Set Modes”.
3.2. SAFETY STOPS
Safety stops are widely considered “good diving practice” and are an integral part of most dive tables. Reasons to perform a safety stop include a reduction in sub clinical DCI, microbubble reduction, ascent control, and orientation before surfacing.
The Vytec displays two different types of safety stops: Recommended Safety Stop and Mandatory Safety Stop.
The Safety Stops are indicated by:
-STOP label, when in the depth range 3 m – 6 m [10 ft - 20 ft] = Recommended Safety Stop Countdown
-STOP+ CEILING label, when in the depth range 3 m – 6 m [10 ft - 20 ft] = Mandatory Safety Stop Time display
-STOP label, when deeper than 6 m = Mandatory Safety Stop scheduled
3.2.1. Recommended Safety Stop
With every dive over 10 meters the instrument has a three minute count- down for the recommended safety stop, to be taken in the 3 - 6 meter [10 ft - 20 ft] range. This is shown with the STOP sign and a
The Recommended Safety Stop, as the name implies, is recommended. If it is ignored, there is no penalty applied to the following surface inter- vals and dives.
