Suggested method of scanning logs This procedure will insure that the entire surface of the log is scanned by the metal detector. Place search head close to the log surface and scan the entire length of the log as shown in diagram to left.
Roll log over as required to expose unscanned surfaces.
Scan the rest of the circumference of the log covering the complete surface of the log. Overlap longitudinal sweeps to prevent dead spots.
