HOW TO WEAR THE JACKET
You can wear the jacket either out of the water or in the
water.
It is absolutely necessary to learn how to correctly
wear the tanks and the jacket during the diving course.
The jacket is fastened to the diver's body with shoulder
straps and a cummerbund.
The main fastening is assured by a cummerbund with
abdominal strip and Freematic system that fits every
waist and provides the best fastening and a rapid
adjustment of the jacket to the body without compression
on the chest and the waist.
An additional adjustment is provided by the adjustable
shoulder-straps with large front quick-release buckles;
the tank is fixed to the back-piece by means of an
adjustable band, so that it is possible to adjust tanks of
different diameters.
Now, once you have rapidly checked for the correct
operation of the inflator, the hoses and the accessories,
you are ready to dive.
To check for correct inflator operation, before
each diving, it is recommended to operate the
by-pass controls several times, trying to press
the inflation push-button and, in particular, to
move the deflation slider.
OPERATION
The jacket operation is controlled by the by-pass, the
deflation valve and the overpressure valves.
To begin a dive, you must deflate the inflated jacket by
either moving the slider controlling the deflation valve or
operating the overpressure valve.
As previously said, you can have a gradual deflation by
moving the slider across its stroke or a quick deflation by
immediately taking the slider to the end of its stroke (Fig. 14).
Now, you can descend at a descending rate that
increases in proportion
compressing you.
To descend slowly you can inflate.
By lightly pressing the inflation button, you can modify the
descent rate and then progressively adjust yourself to
the increasing depth (Fig. 14).
