Marker Locators for EMS & RFID Markers
Locate passive markers quickly and confidently. Modern receivers pinpoint ball and disk markers with accurate depth readouts, and—on RFID models—read/write IDs for reliable asset identification.
- Detects standard EMS markers & Smart RFID markers
- Utility-specific frequency profiles for clear attribution
- Depth indication & pinpoint guidance for precise locating
- Optional RFID read/write, data logging, GPS/connectivity
- Rugged, field-ready design for construction & operations

What do marker locators do?
Marker receivers detect the characteristic field of passive markers underground. With Smart RFID markers, devices can read—and depending on the model—write IDs and data, enabling positive identification and reliable documentation.
Key features
- Frequency profiles: select utility-specific marker frequencies
- Pinpoint & depth: visual/audio guidance with depth readout
- RFID functions: ID reading, optional data capture/write
- Documentation: store points, optional GPS and data export
- Ergonomics: clear displays, one-hand operation, IP protection
Selection guide
- Marker type: EMS only or EMS and RFID support?
- Depth & environment: sensitivity, pinpoint accuracy, noise rejection
- Workflow: logging/GPS, interfaces, battery runtime
- Accessories: marking rods, carry solutions, spare batteries
FAQ
- Do EMS and RFID markers locate differently?
- Both can be located; RFID adds unique ID reading and, with suitable devices, data writing.
- How accurate is depth?
- Accuracy depends on marker size, soil and receiver. Pinpoint guidance and correct alignment improve results.
- Which frequency should I use?
- Use the utility-specific marker frequency (e.g., water, power, gas). Receivers provide matching profiles.
- Can I write data to markers?
- Only on Smart RFID markers with devices that support writing. Standard EMS markers have no memory.
