❓ Frequently Asked Questions (FAQ)
Q1: What Rf Markers Can The Radiodetection Mrx Rf Marker Locator Detect?
A. It supports the most common RF markers including marker balls, near-surface, mid-range, and full-range types.
Q2: What’s The Difference Between Mrx, Mrx G, And Mrx Sg?
A. MRX provides dual-function locating; MRX G adds onboard GPS and logging; MRX SG adds centimetre-level RTK mapping capabilities.
Q3: How Do Power Filters™ Help In Congested Areas?
A. Power Filters™ analyse harmonic content so you can tell if a signal comes from one source or multiple cables, helping you trace the correct route.
Q4: Can The Radiodetection Mrx Rf Marker Locator Find Sheath Faults?
A. Yes. Combine the locator with an A-frame accessory to identify and pinpoint insulation sheath faults to approximately 4" (10 cm).
