Radiodetection MRX SG — Survey-Grade RF Marker & Utility Locator with Mapping The Radiodetection MRX SG is the most advanced locator in the MRX family, combining precision utility locating, RF marker detection, and survey-grade GNSS positioning in a single professional instrument. Designed for high-accuracy mapping and damage prevention workflows, the MRX SG enables teams to locate, discriminate, and document underground assets with confidence . Survey-Grade Locating & Mapping With integrated survey-grade GNSS , the MRX SG captures high-accuracy geo-referenced locate data while tracing utilities and RF markers. This allows operators to complete locating and mapping simultaneously , eliminating the need for separate GPS equipment. Comprehensive Locate Flexibility The MRX SG supports 5 antenna modes , 8 active locate frequencies , 4 sonde frequencies , and 3 passive modes , making it adaptable to virtually any locate scenario — from shallow utilities to deep, congested infrastructure corridors. Power Filters™, iLOC™, and Fault Find Advanced Power Filters™ help isolate individual power cables in dense networks, while iLOC™ enables wireless control of transmitters from up to 1,400 ft (450 m) away. When combined with an A-Frame accessory , the MRX SG provides Fault Find functionality to pinpoint insulation sheath faults to within 4 in (10 cm) . Built for Enterprise Workflows With Bluetooth® connectivity and mobile integration, the MRX SG supports seamless data transfer to mapping and asset management platforms, making it ideal for utilities, municipalities, and large infrastructure owners.
