Buoyancy on the surface
In order to ensure maximum buoyancy on the surface, before getting into the water (or directly after
ascending) inflate the BC using inflator button. Stop inflating the BC when the automatic dump valve activates.
Before jumping into deep water from a boat or a bank inflate the BC using the inflator button. Getting into
Descent
In order to descend, press the purge button holding the inflator over your head. Use the purge button with
care, as releasing too much air may result in an uncontrolled descent.
Neutral buoyancy
Maintain neutral buoyancy for a given depth during the dive, using the inflator and purge buttons as needed.
In order to ensure precise control over buoyancy you should press the inflator button for a short moment. If
more air needs to be added to the BC, press the inflator button for a short moment several times.
During release of air from the BC hold the inflator over your head, so the air may escape freely.
Ascent
Ascending too quickly may result in decompression sickness. Therefore you must control the rate of ascent by
gradually releasing the expanding air from the BC with the purge button.
Ascending or reducing the depth level too quickly may result in decompression sickness (DCS). Always pay
adequate attention to buoyancy control and respect the ascent rate limits.
water with the BC not fully inflated may result in drowning!
