When working in a muddy field with any pinpoint probe, put it in a plastic see through bag and tie an elastic band around it. This will keep it clean and save the job of cleaning the probe after use.
When detecting a target, use the probe as you would your detectors search coil by crisscrossing over the potential target.The target illumination light is automatically activated when the probe is switched on. This will help the user to see into dark holes and identify objects in poor light conditions. Detection area on probe is along the entire length of the probe area.
