TAC-200D MAINTENANCE
The TAC-200D is very reliable piece of equipment and needs very
little service. It is recommended that the board and all of it’s compo-
nents be rinsed with fresh water after every dive, wiped down with a
clean cloth, and stored in a cool, dry place. Periodically, you need to
disassemble the system and clean all the components separately.
The TAC-200D and its components are designed for the rigors of un-
derwater use and should provide many years of use, but keep in mind
the TAC-200D is a diving instrument and should be treated as such.

Plug U B connector from DG100 Battery
Charger (DG100-01) into the back of the DG100
and then plug the charger into a 110/220 volt
outlet. The DG100 will charge to 100% in 12
hours and charge to 90% in 2 to 3 hours.
In addition, the DG100 can be charged using a standard U B to mini-B
cable connected to a standard PC. This function is also used to change
the state of the of display from Imperial to Metric units. (see page 9)
• MAINTENANCE
Although built for the rigors of underwater use, the DG100 is a preci-
sion tool and should be treated as such. Avoid violent bumps and
drops that could effect the reliability of the gauge. The DG100 is com-
pletely potted and there is very little maintenance involved with the unit.
Do not exceed the maximum depth of 330ft (100M) as this may dam-
age the unit.
O-RING REPLACEMENT
There are two o-rings seated in the battery charging compartment lo-
cated at the back of the DG100. It is recommend that these o-rings get
replaced every 12 to 18 months of use. Please contact RJE Interna-
tional to order these o-rings under part number DG100-02.
SWITCH COVER CLEANNG
Occasionally, the cover over switches “A” and “B” will trap sand and
debris. To clean the switch assembly, remove the switch cover plate by
unscrewing two Allen head screws at the back of the DG100. Remove
plate slowly to ensure that the switch springs do not get lost. Reinstall
the battery cap (to protect the U B connector) and carefully rinse as-
sembly and switch cavity with fresh water. Dry gauge and reassemble.

INTRODUCTION
The TAC-200D Diver Navigation Board was developed and is used by
divers for accurately navigating underwater. Highly reliable and rugged,
the TAC-200D consist of three major components: a rugged high im-
pact plastic board (p/n TAC200-1), a large underwater compass (p/n
TAC200-2), a digital depth gauge with timer (DG100). The TAC-200D
is supplied in a padded carrying case (p/n TAC200-4).
The TAC-200D 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.

• BATTERY CHARGING
The DG100 comes with a rechargeable battery that provides up to 20
hours of continuous use. The battery, can be recharged over 300
times before having to replace the unit. Upon activation, the display
briefly indicates the battery health in a form of percentage, 100% is
fully charged. It is recommended that you charge the DG100 before
every dive.
To charge the DG100, remove the bat-
tery charge cap from

USING THE TAC-200D DIVER
NAVIGATION BOARD
Navigating with the TAC-200D is simple once you understand the
principle “elapsed time” as a method of underwater navigation. The
key to using “elapsed time” is knowing how long it takes to swim a
known distance in a set frame of time. For example, if you consis-
tently travel 30 ft.(10M) in 20 seconds, then you can estimate the dis-
tance you travel by timing the length of your swim over a given com-
pass heading. To be fairly accurate, you must set this “benchmark”
by swimming at a normal relaxed pace.
Once you have established this “benchmark”, the TAC-200D allows
you to plot and follow a predetermined pattern or course for your dive
instead of randomly swimming around. To understand how to plot a
course, you must understand how the components of the TAC -200D
work together.
Depth and time are tracked on the DG100 depth gauge and timer.
Course heading is monitored by the large underwater compass
mounted in the center of the TAC200-1 navigation board. The com-
pass card has white luminous digits on a black background for better
contrast in poor visibility, and the three compass rose points, North,
East, and West, are highlighted.
Now let’s plot a dive to see how the TAC-200D really works. We are
able to cover a distance of 30 ft. (10m) in 20 seconds, which is our
benchmark. Using this benchmark, let’s plot a dive to a reef that is
located north of the shoreline, 270 ft.(82m) offshore in 40 ft. (12m) of
water. In planning this dive, we will explore the reef in a westerly di-
rection and then return to our entry point.
For the first leg of the dive we will plot a course along a heading of 0°
north for 3 minutes. We should cover a distance of 270 ft. and be on
the reef. Now for leg 2, we will plot a course on a heading of 270°
west for 10 minutes. This means we cover a distance of 900 ft. while
exploring the reef. At the end of leg 2, it’s time to start planning our
return to the entry point. But first, let’s plan on exploiting the area be-
tween the reef and shoreline. To do this, we plot our next course
heading for leg 3 on a heading of 180° south for 1 minute. This
means we will transverse 90 ft (27m) along the bottom toward the
shore. Here, we will turn to a heading of 90° east for 10 minutes
which places us back in the middle of leg 1. Now, all we do is turn to
a heading of 180° south and head for shore.

6 TAC-200D Revision 5
By plotting your dives this way, you become much more efficient
underwater and can truly optimize your bottom time. If you have to map
an underwater site, the TAC-200D becomes a effective tool for the job
as well.
TAC200-1 NAVIGATION BOARD
The TAC200-1 Navigation Board is a rugged high impact plastic board
that is the base for the TAC-200D Navigation ystem. The TAC200-2
Underwater Compass and the DG100 are both mounted onto the
TAC200-1 to complete the system. The hardware used to mount the
TAC100-2 Underwater Compass is made out of non-corrosive material
and should provide you with many years of service.
TAC200-2 UNDERWATER COMPASS
The TAC100-2 Underwater Compass is designed and manufactured
for the rigors of underwater use. The rugged housing is depth compen-
sated and should give you many years of dependable
use with proper care. A black compass card with lumi-
nous 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. This excites the luminous properties of the card and allows
you to visually see the compass at night or in poor visibility conditions
for up to eight hours. The longer you excite the card with light, the
longer it glows underwater.
The TAC200-2 Underwater Compass requires very little care. However
it is a precision instrument and should be treated as such. The entire
compass should be periodically removed from the TAC200-1 Board
and rinsed with clear water and dried with a soft cloth to maintain clear
vision. If air bubbles appear in the dome or any other problems should
occur, contact RJE International, Inc. for service.
TAC-200D Revision 5 7
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) and is altitude
compensated to 6,000ft (1,828m). In addition, the DG100 also warns
the diver if he exceeds 33ft (10m) with a flashing indicator on the dis-
play.
The DG100 also tracks the dive time automatically once activated,
and will store the total dive time upon surfacing. In addition to tacking
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 “ urface Mode” and the surface timer activates.
While in “ urface Mode” the DG100 memory can be accessed allow-
ing the diver to recall his deepest excursion and display it. When re-
calling the max depth, the total dive time is also displayed. Other
depth gauges can be supplied with the TAC-200D series board. Con-
tact a RJE International sales representative to discuss these options.
Display and Controls
Depth readings are provided to the diver through a large Red LED
display on the bottom of the display. Both dive and leg times are dis-
played at the top of the display. The DG100 buttons allow access to
these functions. Using an built in ambient light sensor, the DG100
automatically adjust brightness of the display.
All functions of the DG100 are controlled through buttons on each
side of the display. Buttons are operated in two modes hort Press or Long
Hold. In hort Press operation it is the release of the button that performs the
desired function, this is intentional so as to avoid accidental button activation.
A Long Hold is defined as lasting 2 seconds or more.
