Buried line locator. LED and LCD signal strength indicators make it quick and easy to find exact line location. Lightweight and ergonomically balanced. Automatic signal boost makes it easy to trace lines, even those with very weak signals. Receiver may be used in active or passive mode. Receiver locates multiple passive frequencies with a single setting. Receiver automatically locks out passive range when it detects a transmitter signal, reducing the chance of tracing other lines carrying weaker signals. Microprocessor-based circuitry delivers increased accuracy and features auto-gain control in all environments. Traces 20 ft underground and provides depth readings up to 15 ft.
