Abstract
The invention is a multi-sensor device which generates a signal comprised of one or more electromagnetic waveforms, that are transmitted against a first target material, such as a wall, whereupon said wave or portion thereof is reflected by a first surface and a second wave or portion of said first wave will penetrate the target material and be reflected in part by a second surface for the purpose of ascertaining if the cavity between said first target surface and said second target surface contains a quantity of United States currency.
