Types of Eclipse Transmitters
DCI manufactures four different battery-operated Eclipse transmitters—a standard transmitter (black
tube), a short-range mini transmitter (gray tube), a long-range transmitter (light-gray tube), and a dual-
frequency transmitter (lavender tube). We also offer a cable transmitter (see Cable System section for
information on the cable transmitter). For especially difficult locating jobs, such as when walkover locating
is not possible, DCI offers the SST wireline transmitter, which is part of the Eclipse SST advanced HDD
guidance system. For deep auger-boring applications, we offer a 60-in. (1524-mm) auger-boring cable
transmitter that can be tracked for line and precision grade down to 200 ft (61 m). Call DCI or visit
www.digitrak.com for more information on these products.
The standard Eclipse transmitter emits a 12-kHz signal and provides a depth range of approximately 50 ft
(15.2 m). The standard transmitter is 15.00 in. (381.0 mm) long and 1.25 in. (31.8 mm) in diameter.
Standard Eclipse Transmitter
The short-range mini transmitter emits a 12-kHz signal and provides a depth range of approximately 15 ft
(4.6 m). The mini transmitter is 8.00 in. (203.2 mm) long and 1.00 in. (25.4 mm) in diameter. DCI offers an
adapter for the mini transmitter to fit in a standard-sized housing. The outer dimensions of the adapter
with the mini transmitter inside are exactly the same as those of the standard and dual-frequency
transmitters (15.00 in. x 1.25 in. [381.0 mm x 31.8 mm]). Call DCI for additional information.
