Easy to Use Single Trigger EMS Marker Locator

Designed with both cost and performance in mind, the Goldak Model MLX Series EMS Marker Locators detect and pinpoint standard Electronic Marker System (EMS) markers, at specified depths or greater. The unique instrument housing unfolds from a compact, easily storable form to a lightweight, ergonomic form that is easy to carry. Operation of the MLX series is simple, relying on the activation of a single trigger on the gun-style pistol grip. An internal microcontroller guarantees precise performance and provides other features such as marker depth approximation, auto-shutdown, and battery status monitoring.
