The MXL4 Precision Locator represents a significant advance in cable detecting and tracing capabilities.

Two versions of the MXL4 are available; the MXL4-D which has full data logging capability, and the MXL4-DBG which has full data logging capability, Bluetooth™ connectivity and GPS.

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.

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

OVERLOAD PROTECTION
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.

MULTI-FREQUENCY
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.

DEPTH MEASUREMENT
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.

SIGNAL CURRENT MEASUREMENT
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.

INTELLIGENT NEW FEATURES:

ALARM ZONE
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.

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

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

DATA LOGGING
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.

DATA LOG TRANSFER via USB
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).

DATA ANALYSIS
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.

GPS
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.

CALIBRATION
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.

AUTOMATIC DAILY SELF TEST (ADST)
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*.

PRODUCT VALIDATION CERTIFICATION
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. The PC Toolkit can also be used to view and print a copy of the original factory Calibration Certificate.

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

HIGH RESOLUTION BACKLIT DIGITAL DISPLAY
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.

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

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

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

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