Pinpointing pipe location is difficult without using the visual aids from the display to measure signal level. It can be difficult to discern slight variations in audio signal levels. Always adjust the sensitivity to maintain a mid-scale meter reading while locating. Typical location accuracy is plus or minus one pipe diameter. Always probe or expose the pipe to confirm the exact location before performing any excavation.

The best location results are obtained by beginning your tracing at least 5 meters from the location where the Pulsed Transmitter is connected. The signal levels are normally too strong in the area immediately surrounding the Pulsed Transmitter.

Once the pipe location is determined, it is possible to quickly trace the pipe along this heading and confirm any changes in location by periodically taking readings.
