Introduction.
The watch computer Drake by Cressi is a recreational advanced tool. It will provide all the necessary
information as regards depth, dive times, possible need of decompression, descent and ascent rate and all
the surface intervals between dives. It also provides average data for each session and a separate and
special counter instantly shows the relationship between surface time and diving time. This information is
shown on the device's special display that allows an easy and direct "dialogue" between the diver and the
computer, ensuring a clear understanding of all the data needed at any given time and a perfect readability
in any situation. The computer is provided with clock, a chronograph and calendar and a versatile dive
