The purpose of the Detectable rod is to be able to accurately locate existing underground ducting or to locate the position of a blockage within a duct. Detectable Duct Rodders are available in 5/16" and 7/16" diameter rods. They are available in the 200' to 1000' lengths

Each detectable Duct Rod unit is supplied with a terminal box mounted on the frame with male and female banana terminals for external hook up. Both sizes of rod have #22 guage copper wire down the center of the fiberglass core. It is recommended that a Roller Guide always be used in order to better make the connection between the end of the rod and the wall of the ducting. This is necessary in order to complete the circuit back to earth.

Any transmitter can then be hooked up to the terminal box with the second lead from the transmitter going to ground (spike into earth). Once switched on, the signal will be transmitted along the duct rod and a standard locator can then be used to locate the signal source from above ground.
