Roll/Pitch Check
At the end of the bore path, have a coworker install batteries in the transmitter to power it up. With the
receiver positioned on the intended bore path, have the 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. In particular, note any locations where you lose the update meter bars and/or inaccurate
pitch or roll readings are observed.

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 drilling under metallic objects. The greater the separation between the
receiver and the metal, the better the receiver’s antenna will read the signal. Another recommendation is
to use a transmitter with a stronger signal strength that may be able to overcome the interference/
background noise.
