RF (Radio Frequency) Marker Locator

An RF marker locator finds buried utility markers that transmit or reflect a radio signal underground. Ball markers and electronic markers get buried alongside pipes, cables, or valves during installation, sitting anywhere from 30cm to 1.5 metres deep. The locator sends a signal down and reads the response, showing the marker’s position and depth on a screen without digging test holes. Detection range varies by marker type, typically 1 to 3 metres deep for passive markers, and up to 5 metres for active RF tags with battery power.

Handheld units weigh between 1 and 3 kilograms, with a shaft length of 90cm to 1.2 metres for standing operation while walking a survey line. Screens show signal strength as a bar graph or numeric value, with an audio tone that rises in pitch as the operator gets closer to the marker. Some models store GPS coordinates alongside each find, useful for building a location map of buried infrastructure over a large site. Battery life runs 8 to 15 hours per charge, enough for a full day of fieldwork.

Utility companies use these locators before excavation work, confirming exact pipe and cable positions to avoid accidental strikes during digging. Telecom firms use them to find buried fiber markers when planning new connections or repairs. Security teams protecting sensitive sites also use RF locators to map buried cable runs for perimeter alarm systems, keeping records accurate as infrastructure gets added over time.

Tactical Supply Pakistan supplies RF marker locators to utility companies, telecom contractors, and infrastructure security teams across Pakistan. Units come with a carry case, spare battery, and a quick reference guide for matching locator settings to marker type.
