Transmitter
Long-Range Eclipse Transmitter
The long-range Eclipse transmitter emits a 12-kHz signal and provides a depth range of approximately
85 ft (25.9 m). The long-range transmitter is 19.00 in. (482.6 mm) long and 1.25 in. (31.8 mm) in diameter.
This transmitter requires the use of one 3.6-V DCI SuperCell Lithium Battery. The use of two C-cell
alkaline batteries will result in very short battery life—approximately 2 hours. Therefore, DCI recommends
that you only use the SuperCell Lithium Battery in the long-range transmitter.
Eclipse Dual-Frequency Transmitter
The dual-frequency transmitter is the same size as the standard transmitter, and it can be set to transmit
in dual-frequency mode (sending signal at both 1.5-kHz and 12-kHz frequencies) or in single-frequency
mode (sending signal at 12 kHz). Each frequency mode offers specific advantages:
¾ The dual-frequency mode provides a depth range of approximately 40 ft (12.2 m) at either fre-
quency, and is recommended in areas where rebar, wire mesh, or other metal (passive) inter-
ference may be encountered.
¾ The single-frequency mode (12 kHz) provides a depth range of approximately 60 ft (18.3 m) and
is intended for use in areas of active interference.
When using the standard Eclipse transmitter (black tube), the mini transmitter (gray tube), the long-range
transmitter (light-gray tube), or the dual-frequency transmitter set to single-high (SH) or dual-high (DH)
mode, you should see Low Fre on the receiver’s main menu display (meaning you are operating at high
frequency). When using the dual-frequency transmitter set to dual-low (DL) mode, you should see High
Fre on the receiver’s main menu display (meaning you are operating at low frequency).
Pitch and Roll Information
Eclipse transmitters measure pitch in percent slope or degree increments. Pitch measurements are
displayed in 0.1% increments from 0% to ±100% (or 0° to ±45°).
The transmitter roll is displayed in 24 positions, similar to the hour and ½ hour positions on a clock.
