Diving – Vsi - xDEEP BLACK BT User Manual

18. DIVING – VSI
The state-of-the art VSI indicator provides accurate buoyancy control and both
ascent and descent speed. It displays not only the current speed rate in meters per
minute, but also shows the rate in relation to the set optimal and max. speed. The
VSI indicator is displayed on the main screen and compass screen, to their left.
When you maintain neutral buoyancy, the indicator does not deflect to any
direction. When you start descending or ascending, the indicator will deflect
appropriately down or up. The deflection volume corresponds to the descent or
ascent rates.
Optimal ascent rate level
Graphic indicator of current ascent/descend speed.
8 Ascent or descent rate in m/min.
Optimal descent rate level.
The indicator colour depends on ascent/descent rate: standard colour
corresponding to the range from zero to optimal rate; warning colour corresponding
to the rate exceeding the optimal one, and alarm colour corresponding to the rate
exceeding the max. one.
Attention! Too fast ascent may cause decompression disease (DCS).
Before diving always check correct speed settings for VSI indicator!
