Radiodetection MRX — RF Marker & Precision Utility Locator The Radiodetection MRX is a versatile RF marker and precision cable and pipe locator designed for professionals who need reliable detection of both buried utilities and RF marker balls in a single, rugged platform. Engineered for daily field use, the MRX combines advanced signal processing, flexible locate modes, and operator-focused ergonomics to support accurate tracing in complex underground environments. Advanced Locate Capability Across Multiple Signals The MRX supports 5 antenna modes, 8 active locate frequencies, and 4 sonde frequencies, allowing operators to adapt to a wide range of locate scenarios — from tracing metallic utilities to pinpointing non-conductive pipes fitted with sondes. With 3 passive locate modes, operators can detect power and radio signals when direct transmitter connection is not possible. Power Filters™ for Complex Power Networks When tracing live power cables in congested networks, conflicting signals can overwhelm standard locators. With Power Filters™ , the MRX uses the harmonic properties of power signals to determine whether a signal originates from a single cable or multiple sources, enabling confident discrimination and accurate route marking with a single button press. Expandable Capability with iLOC™ & Fault Find The MRX supports iLOC™ , providing a wireless link between the locator and compatible transmitter. Operators can remotely adjust transmit power and frequency from distances of up to 1,400 ft (450 m) — reducing walking time and increasing locating efficiency. When paired with an optional A-Frame accessory, the MRX enables Fault Find capability, allowing operators to identify and pinpoint insulation sheath faults to within 4 in (10 cm).
