Abstract
A compact line illuminator for applying an oscillating signal to buried or otherwise inaccessible pipes, cables and conductors so that their location can be traced by detecting an electromagnetic signal emitted by these buried objects. The illuminator includes a circuit for generating a signal suitable for tracing a buried conductor and a holder for a portable power source that can energize the circuit. First and second leads each have a first end connected to the circuit and a second end connected to a corresponding mechanism such as an alligator clip for attaching to a buried conductor. A case encloses the circuit and the portable power source holder and is configured for having the first and second leads wrapped around an exterior of the case. Mechanisms are provided for holding the leads wrapped around the exterior of the case.
