Abstract
Provided are products used to detect and methods for detecting conductive materials in the presence of non-conductive materials, including non-conductive materials having dielectric properties. Specifically, the product is a conductive thin film detector, which is, preferably, a hand-held device designed to detect the presence of metal in, on, or under an object. This detection occurs even in the presence of non-conductive materials and other nearby conductive materials on objects that are not being tested. The device preferably includes: a power source, such as a battery; a method for activation, such as a press button; the necessary components to send and receive a radio frequency, e.g., a radio frequency generator, an antenna, and a radio frequency detector; and an indicator, such as a light or a meter, to, for example, indicate the strength of the radio frequency signal received.
