Types of LT2 Transmitters
DCI manufactures two different battery-operated transmitters for use with the LT2 system—the standard-
range LT transmitter (bright-green tube) and the short-range LS2 transmitter (brown tube). The transmitter
fits inside the drill housing and transmits information regarding the drill head location, position, and
heading. An index slot at the front end assists in properly aligning the transmitter in the housing. The
transmitter emits electromagnetic signals at a frequency of 12 kHz that the LT2 receiver “hears” and
converts into the information shown on the receiver and remote display screens.
The transmitter and receiver must both have matching global designation numbers to ensure that they
comply with regional operating requirements. The global designation number is located near the serial
number on the transmitter’s battery compartment, as shown by the number inside the globe icon (
) in
the photo below. This number must match that of your receiver for proper communication. To determine
your receiver’s global designation number, see the startup screen shown under “Turning On the
Re
ceiver” in the Receiver section.
The sta
ndard-range LT transmitter provides a depth range of 40 ft (12.2 m) and is 15.00 in. (381.0 mm)
long and 1.25 in. (31.8 mm) in diameter. It is powered by two C-cell alkaline batteries or one DCI
SuperCell lithium battery.
