DG100 Digital Depth Gauge and Timer
The DG100 is a digital depth gauge that measures and displays depth
accurately from 0 to 330ft (0
-
100m). Using a state
-
of
-
the
-
art pressure
transducer the DG100 depth resolution is 0.1ft (0.1m).
The DG100 also tracks dive time automatically once activated, and will
store the total dive time upon surfacing. In addition to tracking the total
dive time, the DG100 also tracks leg times. The leg time functions are
independent of the dive time. Upon surfacing, the DG100 switches to
“
Surface Mode
”
and the surface timer activates. While in
“
Surface
Mode
”
the DG100 memory can be accessed and allows the diver to
recall and display their deepest excursion. When recalling the max
depth, the total dive time is also displayed.
Display and Controls
Depth readings are provided to the diver through a large Red OLED
display on the bottom of the screen. Both dive and leg times are
displayed at the top of the screen. The DG100 buttons supply access
to these functions. All functions of the DG100 are controlled through
buttons on each side of the display. Buttons are operated in two
modes: Short Press or Long Press. Short Press is defined as less than
1 second. Long Press is defined as lasting 2 seconds or more.
