Product Description
Key Features
Multiple Detection Modes
Auto, Power, Radio, and Transmitter modes detect a wide range of buried utilities without manual frequency selection.
Depth Estimation
Measure line and sonde depth from 0.3m to 3m (1–10 ft) with ±10% accuracy when used with a signal transmitter.
Hazard Zone Indicator
Visual alert warns the operator when the locator detects a buried utility in close proximity — before you dig.
Audio Guidance
85 dBA tone guidance at 30cm helps operators accurately trace buried utilities by sound in noisy site conditions.
15-Hour Battery Life
6× AA alkaline batteries deliver a full day of continuous operation without recharging. Standard batteries available anywhere.
IP54 Weatherproof
Protected against dust ingress and water splashes — designed and tested for demanding construction job site conditions.
