Using the Locator: Tracing

Having pinpointed a service it should now be possible to trace its route.

1. Carefully follow the direction of the signal holding the Locator at right angles

to the line of the signal. It is necessary to constantly ‘slice’ the Locator from side

to side in order to be sure of still being over the peak signal response.

2. Stop and mark the position of the signal at regular intervals. As more marks

are recorded the precise direction of the service will become more apparent.

Lost Signals

This can be because of a curve, or bend in the route, change in depth of the

service, a T connection or the end of the service.

Finding Lost Signals

1. Locate in a circle at least 1 metre around the point where the signal was lost.

This should locate the service if it has simply changed direction sharply or T’d

into another service.

2. If you find nothing then increase the sensitivity and repeat the circle.

This should find the service if it has continued but at a greater depth.

NOTE It may be necessary to re adjust the sensitivity to maintain the

optimum response.

NOTE After tracing, return to the original search grid to search for

further buried services.

WARNING Never rush the tracing process. Small and unexpected changes in the service’s route will be

missed if care is not taken to follow the signal’s path every step of the way.
