Situation What to try
Signal is lost. Walk in a circle to detect a tee or bend in the line.
Signal varies from low to high and is
unstable. Mark as a hand-dig area.
You are near a power line and are
receiving interference. Sweep the area in 60P mode. If receiver gives a strong
signal response, a power line is interfering with transmitter
signal.
Receiver does not function properly. Receiver gain could be set too high or low. Lower or raise
gain to locate the line. See “Controls” on page 13.
Target line has connections to other lines. Disconnect target line from other lines or use direct
connect or induction clamp to focus signal on target line.
Signal is transferring to other lines. • Lower the power level.
• Use direct connection, if possible, or use induction
clamp.
• Move the ground stake away from the target line and
away from other buried lines.
• Apply signal at the point where the target line is
farthest from the other lines.
