MRX SG Survey Grade Locator

Radiodetection® MRX SG Survey Grade Locator

Triple Utility Detection. Survey-Grade Accuracy. Built for the Field.
The Radiodetection® MRX SG Survey Grade Locator combines industry-leading utility detection with integrated GNSS mapping and RF marker location—all in a single, ruggedized platform. With 21 active locate frequencies, 7 antenna modes, and centimeter-level accuracy via RTK correction, the MRX SG is engineered for professionals who demand speed, precision, and data integration in high-stakes utility locating environments.

Triple Functionality in One Device

Locate utilities. Map assets. Detect markers.
Designed for contractors, municipalities, and subsurface utility engineers, the MRX SG simplifies fieldwork by integrating line locating, marker ball detection, and survey-grade GPS mapping into one streamlined tool.

• 21 active frequencies (ELF to 200kHz)
• 4 sonde frequencies: 512Hz, 640Hz, 8kHz, 33kHz
• 5 passive modes including Power, Radio, CPS, CATV, and Passive Avoidance
• Simultaneous mapping and utility detection for faster workflows

Built for Complex Environments

Engineered for dense infrastructure and variable signals.
With 7 antenna modes including Peak+, Guidance, and Current Direction (CD), the MRX SG excels in congested urban areas and high-impedance utility detection. The 4kHz frequency with CD is particularly effective for tracing telecom and streetlight cables in difficult terrain.

• Enhanced signal discrimination using Power Filters™
• Accurate tracing in RF-noisy zones
• Fault-locating A-frame accessory pinpoints sheath faults to within 4"
• Continuous depth estimation during active locates

Tailored Utility Locating

Programmable frequencies for system-specific challenges.
Buyers can program up to five custom frequencies (50Hz–1kHz, in 1Hz steps) to match proprietary utility networks. This level of configurability ensures adaptability to evolving infrastructure and client-specific detection requirements.

• Custom frequency support for specialized networks
• Compatible with marker balls for plastic pipe locating
• Real-time auto-logging of locate parameters for compliance

Productivity-Driven Design

Ergonomics and automation reduce operator workload.
With an intuitive user interface, long battery life, and streamlined menu navigation, the MRX SG enables teams to hit the ground running—even with minimal training.

• Lightweight, balanced design for all-day use
• Google Maps™-based RD Map+ interface for intuitive asset logging
• Smart integration with fleet tools like C.A.T Manager Online
• Simplifies training and onboarding for large teams

Toughness & Reliability

Field-hardened for daily use in demanding conditions.
From construction zones to cold-weather excavation sites, the MRX SG is built to endure harsh environments and constant use. Radiodetection’s reputation for equipment longevity and serviceable design reduces downtime and long-term cost.

• IP-rated housing for water and dust resistance
• Backed by Radiodetection’s global support network
• Compatible with calibration and service platforms for fleet oversight

Damage Prevention & Safety

Detects what others miss—protects what matters.
With its ability to locate buried plastic and non-conductive utilities using RF markers, and its Passive Avoidance Mode for simultaneous power and radio detection, the MRX SG reduces the risk of accidental strikes.

• RF marker detection for locating plastic or non-traceable assets
• Passive Avoidance improves awareness of live power hazards
• Real-time depth and signal strength readings for safer excavation planning
