RF Utility Marker Locator

An RF utility marker locator finds buried markers placed alongside pipes, cables, and conduits at the time of installation. The locator sends a signal into the ground and reads the response from a marker below, showing depth and position on screen without any digging needed first. Detection depth typically runs from 30cm to 1.8 metres, depending on soil moisture and marker type, with signal range extending up to 3 metres for stronger active markers. Passive markers hold a resonant circuit with no battery, while active markers use a small internal battery for a longer detection range.

Handheld units weigh between 1 and 2.5 kilograms, with a shaft length of 90cm to 1.2 metres for comfortable use while standing and walking a survey line. Screens show a numeric depth reading alongside a signal strength bar, and an audio tone rises in pitch as the operator nears the marker’s exact position. Frequency selection lets one locator tell apart different utility types buried close together, such as water, gas, and telecom lines sharing the same trench route. Battery life on the locator runs 8 to 15 hours per charge, enough for a full working day without a recharge.

Utility companies use these locators before any digging work, confirming exact pipe and valve positions to avoid strikes during excavation. Telecom contractors use them to relocate buried conduits when planning new connections through existing streets. Municipal survey teams also rely on marker locators to update infrastructure maps, since older records often don’t match what’s actually buried underground after years of repairs and additions.

Tactical Supply Pakistan supplies RF utility marker locators to utility companies, telecom contractors, and municipal survey teams across Pakistan. Units come with a carry case, spare battery, and a frequency chart for common marker types.
