Recognizing Iron
The Pathfinder V3 has the capability to be set to completely ignore iron objects such as wires and nails of size up to 15 cm.
Iron is not indicated by the LED meter, but it is indicated by the lower tones on the sound. Low tone - Iron, high tone - non-ferrous.
The Threshold has to be audible at all times, this ensures detection of deep targets. When you hear a lower pitch tone than the one on the Threshold and the sound level goes above the Threshold level, and no meter reading, this will always be Iron.
