Amprobe AT-3500 Underground Cable Locator

Locates underground energized and de-energized wires, cables and pipes.

View larger What's in the Box? The AT-3500 can be used in different modes for optimal tracing in any situation. Identify the Location and Depth of Underground Cables, Pipes and Wires 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. Expert Features for Any Situation 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. Additional Features The AT-3500 transmitter has two signal strength settings. The low-output 0.1 watt (W) signal strength setting conserves battery life and the high-output 0.5W signal strength setting enables long distance tracing. The transmitter can also provide a pulsing signal to conserve battery life, improve detection when then signal is weak, or distinguish the transmitted signal from interference in the area in addition to providing a continuous signal for an accurate depth reading. The transmitter has a battery charge indicator that shows when it is low on life. Likewise, the receiver has a battery charge indicator as well as two signal gain settings for adjusting signal sensitivity. In automatic signal gain mode, the receiver adjusts sensitivity based on the strength of the signal emitted by the buried utility. In manual signal gain mode, the user adjusts the receivers sensitivity for precise locating in areas with interference. A nylon carrying case with wheels helps protect the receiver and transmitter from damage during transportation and storage, complete with a pouch that organizes the ground stake, cables, and alligator clips. It also comes with a ground stake, cable, and alligator clip for grounding the transmitter when it is directly connected to the buried fixture. Product Features
