TAC
-
DG Analog Depth Gauge
Based on the model purchased, there are two different depth gauges
supplied with the TAC
-
200A series diver navigation boards. The TAC
-
DG/80I displays depth from 0 to 80ft and is supplied with part number
TAC
-
200AI. If you purchased the TAC
-
200AM, then the TAC
-
DG/25M
is supplied with the board and it displays depth from 0
-
25 meters. Both
the TAC
-
DG/I and TAC
-
DG/M meets the requirement of CE EN 13319
Norm.
Other depth gauges can be supplied with the TAC
-
200A series board.
Contact a RJE International sales representative to discuss these op-
tions.
The analog depth gauge uses a copper
-
beryllium membrane and me-
chanical measuring system to provide accurate depth to the diver
which is displayed on an easy to read dial with parabolic scale. Using a
black face dial with luminous depth markings makes the TAC
-
DG
series depth gauge easy to read in poor visibility.
*Warning:
The TAC
-
DG depth gauges are designed for use in sea-
water. When using in freshwater, the depth reading will be approxi-
mately 0.29 inch per foot (2.4cm per meter) deeper than indicated.
•
Zero Adjustment
The TAC
-
DG depth gauges also have a
“
zero adjustment
”
feature that
compensates for differences in temperature and ambient pressure. To
make the adjustment, rotate the thumb wheel at side of gauge so that
the
“
zero
”
dial marker is even with the depth indicator.
* Note:
When making temperature adjustment, make sure that the TAC
-
DG has been in the water for a few minutes before making adjustment
to ensure accuracy. Also check adjustment after the end of the dive.
Never make zero adjustment in ambient temperature.
•
Maintenance and Use
The TAC
-
DG is a precision tool and should be treated as such. Avoid
violent bumps and drops that could effect the reliability of the gauge.
Do not exceed the maximum depth of depth gauge as this may dam-
age the unit.
In addition, the TAC
-
DG has a max depth indicator which needs to be
reset before each dive. This indicator is a red needle that is mounted
on the face of the dial. To reset, turn the thumb pad in the center of the
dial face counter
-
clock wise to
“
zero
”.
Rinse the depth gauge after every dive and do not use chemical clean-
ers on the clear bezel.

INTRODUCTION
The TAC
-
200A Diver Navigation Board was developed and is used by
divers for accurately navigating underwater. Highly reliable and rugged,
the TAC
-
200A consists of three major components: a rugged high im-
pact plastic board (p/n TAC200
-
1), a large underwater compass (p/n
TAC200
-
2), an analog depth gauge (TAC
-
DG/25M or TAC
-
DG/80I)
and a chronometer (p/n TAC
-
CHRON). The TAC
-
200A series diver
navigation boards come in two models, the TAC
-
200AI which uses the
TAC
-
DG/80I imperial depth gauge that reads for 0
-
80ft and the TAC
-
200AM that uses the TAC
-
DG/25M metric depth gauge that reads from
0
-
25M. The TAC
-
200A is supplied in a padded carrying bag (p/n
TAC200
-
4).
*Warning:
Check for which model depth gauge is mounted on the TAC
-
200A to insure that you understand how to read the depth gauge be-
fore diving.
The TAC
-
200A allows the diver to monitor depth, direction and leg
time. By using this information, a diver can plot and follow a planned
course during a dive with a high level of reliability.
