AN IMPROVED METAL DETECTOR

Abstract A method for detecting atarget using ametal detector by producing at least twodifferent modulated audio tones, by modulating afirst audio tone with afirst stereo audio modulator signal and modulating a second audio tone with asecond stereo audio modulator signal; and applying at least the first audio tone to aleft side ofan audio stereo target indicator indicative of the target, and applying at least the second audio tone to aright side of the audio stereo target indicator; wherein the modulating of the first audio tone and modulating of the second audio tone, comprises one or more of the following; a modulation of avolume of atone, amodulation of apitch of atone, amodulation of relative harmonics ratios of atone, amodulation of achord richness of atone.
