3.2.3. Deep Stops

The Suunto Vytec allows the user to choose a deep stop algorithm instead or the traditional recommended safety stop. Deep Stops are decompression stops that occur deeper than traditional stops, with the purpose of minimizing microbubble formation and excitation.

The Suunto RGBM model calculates deep stop iteratively, placing the first stop about halfway between the maximum depth and the ceiling depth. After the first deep stop has been completed, another deep stop will be prompted halfway to the ceiling, and so on until the ceiling depth is reached.

The deep stop length can be set to 1 or 2 minutes.

Enabling the Deep Stops disables the Recommended Safety Stops, but the Mandatory Safety Stops due to e.g. continuous ascent rate violations are still prompted.

3.3. DIVING IN AIR MODE

The Vytec has three operating modes: Air mode for diving with standard air only, Nitrox mode for diving with oxygen enriched (EANx) mixtures and Gauge mode for use as bottomtimer. The Air mode is enabled in the MODE- SET-SET PREF-MODEL submode (see section 4.3. “Set Modes”).

3.3.1. Basic Dive Data

The dive computer will remain in the Surface mode at depths less than

1.2m [4 feet]. At depths greater than 1.2 m the instrument will go into the Diving mode (Fig. 3.7.).

All information on the display is labeled (Fig. 3.7. and 3.8.). During a no- decompression stop dive, the following information will be displayed:

your present depth in meters [ft]

the maximum depth during this dive in meters [ft], indicated as MAX

the available no-decompression time in minutes in the center window as NO DEC TIME and as a bar graph on the left side of the display. It is calculated based on the five factors described in section 6.1. ”Operating Principles”.

the water in temperature in °C [°F] in the lower left corner

the elapsed dive time in minutes, shown as DIVE TIME in the lower right corner

the Altitude Adjustment setting on the left side of the center window with a wave and mountain symbols (A0, A1, or A2) (see Table 3.4.)
