Radiodetection MRX SG — Survey-Grade RF Marker & Utility Locator with Mapping The Radiodetection MRX SG is the most advanced RF marker locator in Radiodetection’s MRX family, combining precision utility locating, RF marker ball detection, and survey-grade mapping accuracy in one powerful instrument. Ideal for teams that need both locating capability and geo-referenced utility and marker capture , the MRX SG streamlines fieldwork and documentation for critical infrastructure projects. Triple-Function Precision & Mapping The MRX SG integrates a survey-grade GNSS receiver with advanced RF and utility locating, enabling operators to locate buried marker balls and utilities while capturing high-accuracy positional data for reporting, GIS, and asset mapping. Advanced Locate Modes & Frequencies With seven active antenna modes — including Peak+, Guidance, Null, and Broad Peak — and a comprehensive range of locate frequencies spanning from ELF to 200 kHz, the MRX SG is capable of tracing utilities and weak or deeply buried signals with precision. Passive modes further support detection of Power, Radio, CPS, and CATV signals. Customization & Workflow Flexibility Users can program up to five custom frequencies for specialized networks and use tools like Current Direction (CD) to discriminate between adjacent utilities. The MRX SG also supports Bluetooth® connectivity and mobile integration for streamlined field workflows. Key Features: Integrated survey-grade GNSS for accurate mapping locates Seven active antenna modes and broad locate frequency range Passive detection of Power, Radio, CPS, and CATV signals Custom frequency programming and Current Direction tools Bluetooth® connectivity for mobile workflows Ideal For: Utility and survey teams needing high-precision mapping, RF marker locating, and advanced utility discrimination in complex infrastructure environments.
