DIVE AND SURFACE TIMER
Once the DG100 is activated underwater, a timer starts to monitor the
length of the dive. The DG100 will stop monitoring the length of the
dive once the unit is less than 3 ft (1 m) from the surface for more than
1 minute. After 1 minute near the surface, the DG100 starts to monitor
the surface time for up to 24 hours. The surface interval time will reset
on the next dive, once the unit exceeds a depth of 3 ft (1m).

300 NAVIGATION BOARD
The TAC
-
300 Navigation Board is a rugged, high impact plastic board
that is the base for the board
’
s instruments. The Underwater Compass
(p/n TAC300
-
1), Chronometer (p/n TAC
-
CHRON) and the DG100
(p/n TAC
-
300
-
DG) are mounted onto the board to complete the
system. The hardware used to mount the compass is made out of non
-
corrosive material and will provide you with many years of service.
The TAC
-
300 board uses a TAC
-
LITE (p/n TAC
-
300
-
2) to illuminate
the compass. To activate the TAC
-
LITE, quickly press and release the
button. The TAC
-
LITE has three positions, OFF, LOW, and HIGH.
To install the TAC
-
LITE, slide the tapered end into the holder featured
below. Ensure the activation button is facing down. This will allow you
access to the button. The TAC
-
LITE operates for up to 120 hours of
continuous use. Use a small flat screwdriver to remove the TAC
-
LITE
when needed.

1 UNDERWATER COMPASS
The TAC300
-
1 Underwater Compass is designed and manufactured
for the rigors of underwater use. A black compass card with luminous
heading markers allows you to maintain a course heading, even in the
worst visibility, for up to eight hours. Illuminating the compass can be
achieved by shining a bright light or UV light on the compass card for
several minutes. The longer you expose the card to light, the longer it
glows underwater.
