Equipment
Voyager Dive Computer
Beuchat are marketing a diving computer called the 'Voyager', which
can be used on air, nitrox or just in depth gauge and timer modes.
It has two buttons to toggle between different information displays
and metric and imperial. The lithium 3.6 Volt CR2450 battery is user-replaceable
and there is the option of a PC interface with the related software.
The percentage of O2 is adjustable by the user, from 21 to 50 in increments
of 1%.
Using a Haldane algorithm modified by Dr. Ray Rogers and Dr. Michael
Powell, it covers 12 tissues and a maximum depth of 60m on air or
120m in depth gauge and timer mode. The ascent rate is 18m per minute
from maximum depth up to a depth of 18m and 9m per minute from 18m
to the surface with possible decompression stops from 3 to 18m. Activation
is automatic on immersion or manual and it has automatic altitude
compensation up to a maximum altitude of 4267m.
Other details include:
• Backlight activated by push-button (adjustable length).
