| Optional Equipment MT-2 Mini-Transmitter (Mole) is used to trace non-metallic pipes, pinpoint obstructions and locate concrete septic tanks. When attached to a plumbers snake, the Mole emits a signal detectable at depths of 18 feet using the MAC-51Bx Receiver. |
| Inductive Signal Clamp Increases the versatility of the MAC-51Bx by providing a convenient method of selectively applying the trace signal to conductors covered with non-metallic insulation. | ![]() |
| Magnetic Locating Mode Only the MAC-51Bx receiver is required when operating in the magnetic mode. Just set the Mode switch to MAG, the Gain control to mid-range, and youre ready 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 Transmitter Inductive Mode (HF only) Induction is achieved by placing the transmitter over the target cable/pipe or by using the optional Inductive Signal Clamp. Its the easiest and quickest way to applying a trace signal that is strong enough for tracing most lines. The trace signal generates an alternating magnetic field around the cable which induces a signal into the receivers cable sensor. A sharp null in the audio signal between the two peaks occurs when the receivers 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. This mode has to be used to apply both HF and LF frequencies so that you can use all three features on-the-fly. 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. | ![]() |
