The MXL4 Precision Locator represents a significant advance in cable detecting and tracing capabilities.  Innovative new features have been introduced enabling the MXL4 Locator and MXT4 Transmitter to provide high-end precision performance and a far more flexible approach to pipe and cable location.

The MXL4 Multi Frequency Locator is available in two model types:

  • MXL4-D Precision Locator
    The C.Scope MXL4-D is a high performance digital multi-frequency Precision Pipe & Cable Locator with in-built Data Logging.
  • MXL4-DBG Precision Locator
    The C.Scope MXL4-DBG is a high performance digital multi-frequency Precision Pipe & Cable Locator with in-built Data Logging, Bluetooth™ connectivity and GPS tracking.

Both these products are designed for use with an MXT4 Multi Frequency Transmitter.

Full Description

The MXL4 is able to quickly and accurately detect, pinpoint, trace and identify the widest range of pipes and cables.

Optimised Locator Sensitivity and Noise Rejection means that the MXL4 can deal with the highest levels of background interference found, allowing even the weakest of signals to be detected successfully.

The MXT4 Transmitter now has a greater range of transmitting frequencies allowing improved long distance tracing and utility identification, even on the most congested of sites. A range of frequencies from 512/640Hz up to 131kHz and including the simultaneous dual-frequency 33kHz and 131kHz signal output is ideal for maximising the number of buried services that can be energised and then detected. The MXL4 can apply these frequency signals without direct connection to buried services, using either a Signal Clamp or the simple induction method from ground level, providing a significant improvement in the detection of the smaller diameter or poorly earthed cables.

The MXL4 when used alongside an MXT4 Transmitter will measure and indicate the depth of buried pipes, cables and sondes at the push of a button.

The MXL4 can monitor the true strength of the MXT4 Transmitter signal applied to a buried service irrespective of its depth. This is ideal for identifying the layout of a pipe or cable network.

Key Features


AlarmZone™ alerts operators to the presence of particularly shallow pipes or cables with the exact trigger depth adjustable by the user to best suit local requirements.

The Dynamic SwingSensor which gently alerts the operator if the locator is being swung excessively, potentially compromising the accuracy of any locates.

PeakHold allows operators to quickly and confidently pinpoint the exact position of buried services

The MXL4-D and MXL4-DBG Locators have full data logging capability. A years worth of data can be stored, in normal usage, on both the Locator and the MXT4 Transmitter.

This can be conveniently transferred at any time to supervisors for analysis via a USB cable to a PC (or wirelessly via Bluetooth™ from the DBG model only to a PC, tablet or smartphone).

C.SCOPE PC ‘TOOLKIT’ and ‘RELAY’ Smartphone App
The free-to-download C.Scope PC Toolkit and C.Scope Relay smartphone App analyses the stored data-logs into charts and graphs that illustrate all aspects of the use allowing training requirements to be quickly identified.

The MXL4-DBG with in-built GPS allows a record to be kept of exactly where the Locators have been used that can then be viewed in partnership with Google Earth™ or Google Maps™.

Twelve months of GPS data is stored, in normal usage. This can be conveniently transferred at any time via a USB cable to a PC or wirelessly via Bluetooth™ to a PC, tablet or smartphone to supervisors for analysis. The free-to-download C.Scope PC Toolkit and Relay smartphone App analyses the stored data.

Additionally, the Locators can be paired to third party GPS Survey equipment, via the Locators in-built Bluetooth™ facilitating ‘one pass’ underground utility surveys to be undertaken.

The MXL4 Cable Avoidance Tools do not require periodic recalibration. A fully Automatic Daily Self Test (ADST) tests and confirms that they are functioning at their optimum level each day.

The MXL4 Locators perform an Automatic Daily Self Test (ADST). The ADST checks the functionality of the locator including the receiving aerials each day when it is first switched on. The MXT4 Transmitter also performs a comprehensive Automatic Daily Self Test (ADST)

At the start of each day of use, a positive Automatic Daily Self Test result gives confirmation to the operator that the kit is working at the optimum level.

The result of this test is recorded and stored on memory within the products in-built data files and can be downloaded onto a PC at any time within the following 12 months*.

These test results can be used to produce a Product Validation Certificate using the C.Scope PC Toolkit. In addition, any results of the Self Test that have been carried out in the last twelve months* are available.

C.Scope authorised Service Centres are also able to provide third-party Test and Conformity Certification should you require it to comply with client or internal requirements.

The MXL4 has a large, clear and easy to read backlit LCD mounted behind a protective polycarbonate lens. The display indicates detection mode, signal peak level, depth, signal strength and battery condition. It also displays the Automatic Daily Self Test results.

The speaker can be easily detached for use in noisy work environments.

The MXL4s twin wall construction is robust and durable. It also provides IP65 standard protection against dust and water ingress.

A complete covers off service & maintenance package is available for those customers who require it from C.Scope Authorised Service Centres.

The MXL4 comes with a three year Warranty (conditions apply).
