How to do a sweep search

This is most reliable way of detecting and pinpointing any buried cable or pipe.

The sweep search involves going two ways over a marked out area, each way a right angle to the other ensuring the locator will pass over the service and detect the signal at least once during the search.

Using a Signal Transmitter is more effective

Using a Signal Transmitter when doing a sweep search will help you to locate and trace metallic utilities that don’t have a detectable signal by applying a signal onto the utilities.

Why should I use this method?

  • This is the most reliable way to locate and trace buried pipes and cables.
  • Often buried cables or pipes are there but are not detailed on the map or plan.
  • Some buried utilities might not give off a detectable signal. Using the Signal Transmitter helps to reduce the risk of striking one of these ‘hidden’ utilities.
