Abstract

A metal detector having a receive signal responsive to detected metal objects and having a display panel that can simultaneously display a plurality of phase angles associated with the receive signal. Additionally, the display panel can simultaneously display a second variable associated with the receive signal at each particular phase angle. The second variable is user selectable and can be either (1) a count of the number of times the signal amplitude exceeds a predetermined threshold level at a particular phase angle or (2) the signal amplitude when the signal is at a particular phase angle.
