MRX RF Marker Locator
A rugged, ergonomic RF marker locator that combines utility line detection and marker ball locating in a single tool. Find plastic pipes, fibre optic cables and critical points in dense networks, and switch seamlessly between line and marker detection with no need to change equipment.
Two Tools In One. Locate The Line, Find The Marker.
The MRX is built for accurate, efficient daily use, delivering powerful locate performance with the versatility to switch between utility line detection and RF marker ball locating without swapping devices.
RF markers are vital for locating underground infrastructure such as plastic pipes, fibre optic cables and key network points. Available as near-surface, mid-range, full-range and ball markers, they let crews mark and re-find buried assets long after the trench is closed.
Three Models. From Dual To Triple Functionality.
Choose the MRX that fits your work, from everyday line-and-marker detection to full survey-grade mapping.
Trace buried utilities and identify buried RF markers in one dependable device.
Adds advanced capability for congested networks plus onboard GPS for digital platform integration.
Combines advanced utility locating, marker ball detection and high-accuracy survey mapping.
Colour-Coded By Utility, Detected By Frequency.
Each buried utility uses a standard marker colour and frequency, so the MRX can identify exactly what it has found underground.
Cut Through Congested, Difficult Ground.
Built-in tools help the MRX discriminate between services, find faults and connect into modern data workflows.
Power Filters™
Uses the harmonic properties of power signals to discriminate between multiple cables and establish the signal source.
Fault Find
With the A-frame accessory, pinpoint insulation sheath faults to within 4" (10 cm) of the damage.
iLOC™
Wireless transmitter link to control signal power and frequency remotely from up to 450 m (1,400 ft) away.
RD Manager Online
Windows software for managing locator data across Radiodetection precision and RF marker locator ranges.
Where The MRX Earns Its Keep.
From plastic pipe networks to fibre protection, the MRX is made for the assets a standard line locator cannot see.
Plastic & Non-Metallic Pipes
Find water, gas and drainage lines that carry no traceable signal by locating the RF markers placed along them.
Fibre Optic Routes
Protect buried fibre by marking and re-finding cable paths and critical points without excavation.
Congested Networks
Separate closely-spaced services and identify signal sources in dense urban utility corridors.
Critical Points
Mark and recover tees, joints, valves and splices so crews return to the exact spot years later.
Damage Prevention
Verify utility position before breaking ground to reduce strikes and costly reinstatement.
Asset Records
With MRX G / MRX SG, capture GPS position for mapping platforms and long-term asset documentation.
Locate, Detect, Discriminate And Record.
A single tool that carries a crew from tracing the line to documenting the asset.
Locate the line
Trace conductive utilities with familiar active and passive locate modes and eight active frequencies.
Detect the marker
Switch to marker mode to find near-surface, mid-range and full-range RF markers and marker balls.
Discriminate
Separate multiple cables and identify the signal source in congested ground before you dig.
Record & map
Capture position on MRX G / MRX SG and manage locator data through RD Manager Online.
Build A Complete MRX Kit.
Pair the locator with the transmitter, A-frame, markers and mounts that get the most from every mode.
TX Transmitter
Apply a clean trace signal to conductive utilities for stronger, more confident MRX locating.
