in Remote Steering Window to Steer Tool
As the transmitter approaches the target (receiver), the FNLP will pass underneath and go past the
receiver. At this point, the remote steering is no longer accurate and the receiver must be moved to a
new farther-out location. The distance between the transmitter and the FNLP is dependent upon the
depth and pitch of the transmitter and the topography. When the pitch of the transmitter is 10% or less
and the ground is parallel to the transmitter, the FNLP is ahead of the transmitter by approximately 0.7
times the transmitter depth. As an example, if the transmitter is 8 ft (2.4 m) below ground, the FNLP will
be approximately 5.6 ft (1.7 m) in front of the transmitter (8 ft x 0.7 = 5.6 ft).
Because the receiver has not been used as a walkover tool to track the depth of the transmitter during
remote steering, it will be necessary to calculate the depth based on the pitch information. For more
information about calculating the depth based on pitch, see “Running Off Pitch or Calculating Depth from
Pitch” in the Locating Section.
Finding Firmware Version
The firmware version installed in the remote display can be identified as follows:
1. Place a battery pack in the unit.
2. Click the “on” button.
3. The firmware version will be displayed in the top left window for 2 seconds. When the firmware
version is displayed, the decimal point will not be shown. For instance, firmware version 3.77 will be
displayed as 377.
After releasing the button, the unit will complete start-up and then be ready for use.
DataLog Capability
Current Mark III Remote Displays have two metal studs protruding from the right side of the display case
for optional DataLog module attachment. The DataLog module also has a speaker, so the drill operator
hears the transmitter temperature increase tones and logging tones. Call DCI if you are interested in
obtaining more information on the DataLog Mapping System.
