This is a Schonstedt MAC-51Bx Pipe and Cable locator (Magnetic-Dual Frequency) We have owned this tool in our plumbing business for probably about 4-5 years and it has always worked wonders for us. Due to down sizing of the company we really dont use it much anymore. I looked on Schonstedt's web site and it retails for about $2500 which is around what we paid for it. It comes with everything that it did new (locator, 2 clamps, ground rod, and instructions). Thanks for looking. The MAC-51Bx is the most cost-effective, all-purpose locating system on the market. It consists of a receiver and a transmitter that simultaneously transmits on two frequencies - 571 Hz (LF) and 82.5 KHz (HF). The receiver has a three position switch that lets you change modes, "on-the-fly", between LO, HI, and MAG, for cable and line tracing with break locating, pinpointing a ferrous metal target, or identifying and pinpointing an energized 50/60 Hz power line. In the LO and HI modes, the receiver's audio signal provides a sharp null when its tip is directly over the target. In the MAG mode (no transmitter required) the audio signal peaks when the receiver's tip is over the target. You can trace the 571 Hz LF signal conductively applied to any continuous metal conductor up to 4000 feet. The receiver's on-the-fly mode-changing feature lets you locate a complete break using the LO mode, and then continue on to trace beyond the break in the HI mode, or trace a metal pipe joined with non-conductive gaskets. The MAC-51Bx by simultaneously transmitting 82.5 kHz (HF) and 571 Hz (LF) signals lets you select and compare received audio signals from both frequencies along with magnetic information without having to return to the transmitter. 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. It's 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 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. 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. 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 you're 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. · Two active frequencies for pipe, cable and line tracing · Passive operation for locating iron and steel targets and energized 50/60Hz power lines · Inductive and conductive signal coupling · Extra Heavy Duty Clips and Cable · Five discrete sensitivity settings · Receiver supplied with two environmentally friendly 9-volt lithium batteries · Operating Voltage: 9V (2 alkaline or 2 lithium batteries) · Battery Life: 60hrs, alkaline (on & off usage @ 70ºF), 120 hrs, lithium (on & off usage @ 70ºF) · Audio Output: Approx. 40 Hz idling tone from speaker · Frequency of pulsing tone (increases or decreases) with signal intensity · Weight: 2.64 lb.
