Three frequency metal detector
Lock's Met 30+ 3F metal detector operates at three crystal tuned frequencies-high, medium, and low. The unit's automatic frequency selection chooses the frequency based on the product and its packaging. According to Lock, polywrapped and metallized film wrapped products can both be passed through the Met30+ 3F, rather than operating two machines at two different frequencies.
