The Cable Route Tracer is designed to locate, trace and measure the depth of buried energized power cables. The heart of the instrument is a compact control box attached to a precision-wound, swivel-mounted detecting coil that operates from three basic positions:

• Horizontal: for maximum deflection over the cable
• Vertical: for a null over the cable
• 45° angle: for a null at a horizontal distance from the cable that is equivalent to the cable depth

The receiver of the locator features a filtering circuit that responds only to the existing electrical energy radiating from the buried cable. The chronic problem of identification in congested areas is eliminated, because the receiver is insensitive to telephone lines, gas and water pipes, and steel reinforcing.
