Amprobe AT-3500 Underground Cable Locator

Description

Amprobe AT-3500 Underground Cable Locator. Like new works great. Selling because I just don’t need it anymore.
The Amprobe AT-3500 discovers the location of underground pipes, cables, and wires. Its innovative design allows the AT-3500 to measure depths up to or exceeding 16 feet. The transmitter operates at a 33 kilohertz (kHz) frequency signal, which provides the most reliable results for most locating applications. The Amprobe AT-3500 also comes with a connection cable and alligator clip for connecting the transmitter to the buried pipe, cable, or wire to be traced.
The AT-3500 can be used in different modes for optimal tracing in any situation. The passive power mode locates energized wires with a 50/60 Hz frequency and does not require a transmitter. The receiver alone detects electromagnetic fields emitted by buried energized lines conducting currents. Passive radio mode does not require a transmitter and uses the receiver to detect radio waves coming from cellular towers, radio stations, etc. that are picked up and carried by underground metal objects, such as cables or pipes. The inductive active mode uses the transmitter to wirelessly induce a signal into a buried pipe, cable, or wire. The receiver then detects the signal carried by the buried utility, which enables tracing. In active direction connection mode, the transmitter is connected to the buried utility with test leads (provided there is an available access point to the utility). The transmitter then sends a signal across the wire or pipe, which enables tracing. The AT-3500 can even trace non-metallic pipes that do not conduct a tracing signal. Some of these pipes have embedded metal trace that will conduct signal for tracing. In active inductive or direct connection modes, the AT-3500 can also be used to trace other-nonmetallic pipes by using existing metal wires inside the pipe or inserting metal fish tape into the pipe.
