CAPTION
At the end of the bore path, have your coworker install batteries in the transmitter to power it up. With the
receiver positioned on the intended bore path, have your coworker with the transmitter, step off to your
side approximately 1.5 times the maximum depth of your intended bore. You will now walk back toward
the launch end in tandem, maintaining this distance of 1.5X the max depth while periodically stopping to
change the transmitter’s pitch and roll orientation to verify the speed and accuracy of these readings on
the receiver.
Suggestions for Dealing with Interference
Every job site warrants an interference/background noise check no matter how remote and interference-
free your job site appears to be. If the pitch/roll information becomes erratic or is lost, move the receiver
away from the interference source while staying within range of the transmitter. Separation (use of the
HAG function) may also help when under metallic objects, because the greater the separation between
the receiver and the metal objects, the better the receiver’s antenna will read the signal. Another solution
is to use a transmitter with a stronger signal strength that may be able to overcome the interference/
background noise.
1. Walk the intended bore path with the receiver on and in locate mode, watching for any background
noise that affects the signal strength and could interfere with the transmitter’s signal. The transmitter
must be off during this test. Tolerable levels for background noise vary depending on the depth of the
bore and ground conditions. A general rule is that the background noise should be at least 150 points
less than the signal strength at the bore’s maximum depth. Make note of any problem areas, and take
steps to reduce the interference if possible. See the Safety Precautions and Warnings section for
more information on interference.
NOTE: The high-powered FXL transmitter can be a useful option if the minimum signal strength
requirement cannot be met with the FX transmitter. Other options include getting the
transmitter at depth and level before entering a problem area so that off-track locating or
Target Steering methods can be applied.
2. With the transmitter turned on and in its housing, place the transmitter on the ground. Then place the
receiver to the side of the housing as far as the maximum intended bore depth.
