11 Exiting the water with the HDV
Exiting the water is another delicate moment in the dive and, here too,
the addition of the HDV could be an extra burden.
According to where you started the dive, always make sure the HDV is
the last piece of equipment to recovery. Always put your safety first.
Pay particular attention when exiting choppy water since waves could lift
and launch the HDV against you with even fatal consequences.
12 “Parking” the HDV underwater
When diving you may need to “park” the HDV to continue the dive with
fins only, recovering the HDV later. We strongly recommend you leave
the HDV far from areas with currents that could cause the HDV to collide
with rock walls, the sea bottom or boats. Violent collisions could
compromise the HDV’s hermetic seal and irreparably damage it.
During decompression stops, be careful the HDV does not cause uncontrolled depth
variations, turning it off and leaving it at your side.
DO NOT USE THE HDV TO MAINTAIN THE DECOMPRESSION OBBLIGATION!
13 Descent rate
The HDV allows you to accomplish a fast descent rate. AVOID using it to accelerate your
descent since problems related to equalising and psychological/physical adjustment are
increased.
14 Ascent rate
The HDV MUST NEVER BE USED FOR VERTICAL ASCENTS. In fact,
using it in such a manner may result in an excessively rapid ascent
WHICH IS POTENTIALLY DANGEROUS. Hence it is better to
DEACTIVATE IT BY TURNING THE MAIN SWITCH TO THE OFF
POSITION, position it out of the way, and ascend normally.
15 Using the HDV in apnoea
Diving in apnoea is highly dangerous in itself. The use of the HDV in
apnoea could cause serious accidents. Always be certain and aware of
your capabilities. Adequate training courses are essential for your
safety.
