An apparatus for contactless detection of solid or wet excrement within an underclothing, comprising an enclosure containing an alternating electric current source driving a first alternating current into a magnetic probe consisting of a coil inductor within a parallel tuned circuit that thereby creates a first static magnetic induction field, where the first magnetic induction field penetrates inward through all clothing and induces a second alternating electric current within the solid or wet excrement, where the second alternating electric current is sufficiently minute to prevent health risk to a wearer of the underclothing, wherein the second alternating electric current creates a second magnetic induction field that penetrates outward through said all clothing to reach the coil inductor, wherein the intensity of the first magnetic induction field is reduced based upon the quantity of the solid or wet excrement, whereby the enclosure can be handheld or attached to the outside of the underclothing or any other layer of clothing, thereby requiring no devices or equipment to be located inside or adjacent to the underclothing or within any other clothing and eliminating the need for the underclothing to be specially designed to accommodate operation of the apparatus.
