Figure 19: Ground Balance Procedure

NOTE

Movement of the coil during the entire Ground Balance procedure

should be slow, continuous and smooth and each down and up

movement should take 3 to 4 seconds.

If the Ground Balance OK tone is not heard within

30 seconds of starting the procedure, release the Ground Balance

button and repeat this procedure.

If there is metal in the ground under the coil whilst Ground

Balancing, the detector will not Ground Balance correctly. Move the

detector and repeat the Ground Balance over ground that is free of

any metallic objects.

After the Ground Balance procedure is completed the detector will

automatically cancel interference from the ground under the coil. If

ground conditions change (changing mineralisation in the ground)

this procedure may need to be repeated.
