## Description

The Proster XQ-350 combines a transmitter and receiver to help trace a target cable through a bundle. Sound and LED signals make it easier to follow the strongest indication as you work.

It also checks cable continuity and sequence, helping you identify common wiring faults as well as locate cable ends. That makes it useful for network and telephone cable work at home or on site.

The receiver has an adjustable-volume signal, an LED flashlight and an earphone connection, giving you practical options for tracing in noisy or dim surroundings.

## Tech summary
The XQ-350 is designed for tracing telephone, computer network and other cables. Its transmitter sends a signal that the receiver follows, compare the sound volume and LED brightness to identify the target wire. Turn up the receiver volume before tracing. It does not support testing live wires.

For cable checks, the tester supports continuity testing, sequence collation and open, short or crossed-wire checks. It can also test DC level and polarity, and detect ringing signals. For LAN cables, its sequence scan checks pairs 1, 2, 3, 4, 5, 6, 7, 8 and G. These functions bring cable locating and fault checking together, rather than limiting the tool to a basic continuity check.

A low-battery indicator helps you keep track of power, while auto time-delay power-off is included among its functions. Buyers often describe the tester as straightforward to set up and useful for tracing cables, durability feedback is mixed, with some reporting that their unit stopped working within a year.

## Who it’s for
This cable tester is suited to network engineers, telecommunications maintenance work and DIY home network installation. It can help when several cables run together and you need to identify a particular line, or when a LAN or telephone cable needs checking for an open, short or crossed connection.

For example, when organising network wiring between rooms, use the transmitter and receiver to follow the target cable, then use the sequence and fault checks to assess the connection. The combination is particularly useful if your task involves both locating a cable and diagnosing its wiring, rather than simply checking continuity at an accessible end.

## What you get
The listed contents are a cable transmitter, receiver/tracker, RJ45 cable, RJ11 cable, lead with crocodile clips, instruction manual and earphone. The earphone offers another way to monitor the receiver signal when working in a noisy space, while the flashlight can help when tracing in darker areas.

## Questions before you buy
**Can the XQ-350 test a live wire?** No. It is not designed to test live wires, so use it only on wiring that is not live.

**What cable faults can it check?** It supports checks for open circuits, short circuits and crossed connections, as well as continuity and cable sequence. It also offers DC level and polarity testing.

**Can it trace telephone as well as network cable?** Yes. It is described for tracing telephone wire and LAN cable, including RJ11 and RJ45 cable checks. It can also be used to trace other listed cable types, such as TV cable.

## Buying verdict
Choose the Proster XQ-350 if you want one compact tool for tracing cables and checking common wiring faults. Its transmitter-and-receiver setup, audio and LED guidance, and range of cable tests make it a practical fit for network installation, telecommunications maintenance and hands-on home wiring tasks.
