LineSpotter - cable locator



Code: LineSpotter

The LineSpotter is a cable avoidance tool & live cable locator, designed to locate cables and metal plumbing in walls, floors or ceilings and to identify fuses/ mcb’s.

The LineSpotter is universal equipment intended for tracing hidden conductive paths under plasters in walls, floors, and ground or for determining one wire in a tuft of wires. Fuses or outlets belonging to a certain loop can be located. The LineSpotter helps the operator to resolve hidden line problems easily (short-circuit, interruption).

It consists of a transmitting unit (transmitter), a receiving unit (receiver) and accessories. The transmitter injects emitted signal into the observed installation and this signal is then traced with the receiver. Units are independent of each other.

Accessories, such as a test lead for direct touching of the traced conductor, a voltage output current clamp, and a selective probe, make the LineSpotter even more useful.

The instrument is supplied with all the accessories necessary for carrying out the tests. It is stored in a soft carrying bag together with the accessories.

Most of the electronic parts of the instrument are produced in SMD technology; therefore almost no service interventions are needed.

The principle of the LineSpotter is based on a transmitter and receiver. The transmitter sends a signal of 10.6 kHz, which can be traced or located with the receiver. The receiver can be adjusted into 3 sensitivity modes, low – middle – high. The additional trimmer can do the fine tuning.

The transmitter generates signal, which is connected to a traced object. The state of  an external voltage present at the output terminalsselects one of the two modes of generating the test signal.

In both modes 10.6 kHz signal bursts are injected directly into the connected line or coupled via an optional current clamp.


The highly sensitive hand-held Receiver detects the injected signal around the traced line. It generates sound and visual output relative to the signal intensity. Its constructional designed points with its head detector to the maximum of detected signal and the center of traced object. The slide switch of head detector enables the selection between two built-in sensors.

You can choose between three sensitivities (low, middle and high). An extra potentiometer is added for fine sensitivity adjustment. A buzzer sound and 10-level LED bar graph indicator suffice to indicate the location of the traced object.

Note: always select sensitivity that is optimal for individual tracing. The sensitivity can be changed during tracing.

The receiver is supplied by a 9V alkaline battery (IEC 6LR61).
