    Locate wires and cables

    The Sonel LKZ-720 cable and wire locator is a device consisting of the LKN-720 transmitter and the LKO-720 receiver. This instrument is dedicated to finding cables and other underground infrastructures. The LKZ-720 allows the location of both metallic objects (cables) and non-conductive objects (PVC pipes, concrete, etc.). The locator is mainly dedicated to use in the energy and installation industry, among others.


    • Detection of wires and cables (live or not).
    • Tracing underground cables.
    • Tracing conductive water and heating pipelines.
    • Flow and accurate locating the object.
    • Phase detection mode.
    • Operation in wide range of rated voltage, up to 500 V RMS.
    • Five modes of wire tracer operation: voltage, current, current-voltage, power and clamp.
    • Additional accessories enable precise localization - such as contact or non-contact probes and measurement clamp.

    Special features


    • Receiver operation with max. 4 transmitters at the same time to locate interruptions or distinguish wires.
    • Receiving status information from the LKN-720 transmitter.
    • The function 3D - detecting the direction of current.
    • A LED torch.
    • Headphone socket.
    • Software upgrade via USB.
    • Screen backlight for work in dark.


    • 4 codes of the transmitted signal.
    • Transmission of information about the transmitter settings and battery charge level.
    • Measurement of voltage at the object to 500 V RMS.
    • Three levels of amplification.
    • Automatic or manual selection of operation modes.
    • Screen backlight for work in dark.


    Detection and tracing cables in ceilings, walls and floors

    In response to the needs of customers, the LKO-720 has a specially designed 3D antenna that raises the precision of the wire tracing. Determine direction of wires in concrete up to 5 cm will not be a problem now.

    Multi-transmitter operation

    LKZ enables operation work with four transmitters at the same time. The multi-transmitter operation of the system enables precise location of breaks in an electric system and identify individual cores in the cable or cables in a trench.

    Locating power points and switches in buildings

    Specially modulated and coded signal generated by the LKN-720 transmitter allows to locate and identify sockets and switches in energized and de-energized circuits.

    Identification of fuses on the distribution board

    Thanks to the precise sensor in LKO-720 and additional contact and non-contact probes, identify of breakers and fuses now will be easily and time-saving.

    Possibility to tracing in no access conductors

    LKO-720 with C-8 clamp used in the current mode or in other mode forcing current flow, allows to uniquely identify wire or cable with no physical connection to it.

    Non-contact detection of live cables

    LKO-720 allows to precisely detect energized wires in air and concrete without additional probes. 

    Additional areas of use

    • detection of breaks in cables and wires
    • locating short circuits between leads
    • tracing shielded cables
    • tracing cables in metal ducts
    • tracing underground cables
    • tracing conductive water and heating pipelines
