Features & Applications:
Reduce costly and potentially dangerous mistakes by locating materials below a specified area. This highly productive magnetic locator is the most cost effective, all-purpose locating system on the market.
Magnetic Locator Mode, Only the receiver is required when operating in the magnetic locator mode. Just set the Mode switch to MAG, the Gain control to mid-range, and you're ready to use the magnetic locator to locate underground ferrous pipes, water meters, water valves, and property markers - or anything that has a magnetic field including the 50/60Hz electro-magnetic field generated by energized power lines
Transmitter Inductive Mode Induction is achieved by placing the transmitter over the target cable/pipe or by using the optional Inductive Signal Clamp. The trace signal generates an alternating magnetic field around the cable, which induces a signal into the receiver's cable sensor. A sharp null in the audio signal between the two peaks occurs when the receiver's tip is directly over the cable.
Transmitter Conductive Mode If an exposed section of a target gas or water pipe is accessible, conductive coupling is the most reliable method for applying the trace signal. Providing a good electrical contact between the clip and the conductive portion of the target line by removing rust or paint before attaching the clip is very important.
