Abstract
Excavating with a backhoe or similar equipment has the potential risk of hitting an underground utility which could cause serious injuries and expensive damages. An electronic device that provides a real-time warning of the utility lines immediately ahead of the digging tool and provides an easily interpreted, real-time computer readout of the depth, location, and size buried metallic objects. Developed by Dr. Leonhard E. Bernold, it consists of an active metal detector search coil; a signal processing (control) unit; and a PC computer equipped with an analog-to-digital converter interface.
