Professional Cable Tracker for Electricians

The MASTECH MS6818 is a digital wire cable tracker designed for locating and tracing cables, electrical lines and metal pipes buried in walls or earth. It suits electricians, maintenance engineers and installers who need to identify live circuits, find breaks or verify pipe routes in residential, commercial or industrial environments. It is not for users who require fibre-optic tracing or wireless signal analysis.

Voltage Detection Range 12V to 400V AC/DC

The single specification that determines suitability is the operating voltage window of 12V to 400V AC/DC. This range covers standard low-voltage control wiring through to mains-rated circuits, letting the transmitter inject a traceable signal and the receiver detect it on energised conductors without a separate power-down step.

Transmitter and Receiver Pair with Adjustable

The kit comprises a transmitter and a receiver that both offer mute mode and automatic frequency sweep. Receiver sensitivity is adjustable manually or automatically, while the transmitter runs a self-inspection routine shown on its LCD with backlight. An auto power-off activates after 10 minutes. Additional transmitters can be added to distinguish multiple signals on complex sites.

Questions about this item

What does the 12V-400V range mean when I am testing live circuits?

It lets you trace energised cables from 12 volts up to 400 volts AC or DC without disconnecting the supply.

How does the automatic frequency sweep on the receiver affect tracing accuracy?

The receiver scans frequencies itself, so it locks onto the transmitter signal faster and reduces false picks in noisy environments.

What mounting or physical setup does the MS6818 need before I can start tracing?

The kit is handheld; just connect the transmitter leads to the target conductor and power both units — no brackets or fixed installation required.
