The SubSurface Instruments Cable Drum PL-9202 for the Utility Locator PL-9200 is useful for locating water mains and service lines above ground in areas with congested utilities. The cable drum transmits the transmitter's signal throughout metal pipes that make up an underground utility system allowing the utility locator to detect the utility above ground.
How It Works
First, connect the cable drum to the PL-2000 transmitter. Next, locate two connections to the utility system that you wish to trace. Then, connect the cable drum's red, positive lead to the connection farthest away and its black, negative lead to the closest connection. Set the transmitter to 8 kHz to minimize signal jumping. Finally, use the PL-2000 utility locator to locate the underground pipes between the two connections.
