The Pro871C Underground Cable Locator is a value-priced underground locator for contractors and maintenance personnel. Incorporating 5 different tracking modes (2 direct connect, 2 inductive, 1 passive), the Pro871C tracks many types of cabling, including CATV, electrical, telephone, dog fencing, and landscape lighting, using either null or peak reception modes. Any of the 5 different modes allows users to locate the path of underground cables. Simply connect the transmitter to the wire to be located using the included alligator clip cord set or use either of the 2 wireless inductive modes and turn it on. Then follow the beeping signal with the receiver using the visual meter, the external speaker, or with the included headset.
