Ultra, Locate Active Signals

Special Situations

Situation
Signal is lost.
Signal varies from low to high and is
unstable.
You are near a power line and are
receiving interference.
Locator does not function properly.
Target cable has connections to other
cables.
Signal is transferring to other cables. • Lower the frequency.
What to try
Walk in a circle to detect a tee or bend in the cable.
Mark as a hand-dig area.
Sweep the area in 50 Hz or 60 Hz power mode. If
locator gives a strong signal response, a power line
is interfering with transmitter signal.
Locator gain could be set too high or low. Lower or
raise gain to locate the cable.
Disconnect target cable from other cables or use
direct connect or signal clamp to focus signal on
target cable.
• Lower the power level.
• Use direct connection, if possible, or use signal
clamp.
• Move the ground stake away from the target
cable and away from other buried cables.
• Apply signal at the point where the target cable
is farthest from the other cables.
