Manhole locators allow to determine the position of metal manhole covers under asphalt even at great depths.
The GI series manhole locators allow the location of metal covers, manhole covers for gas-water connections and sewer hatches under any road cover. They are characterized by high detection sensitivity together with great handling and robustness. The patented antenna allows, with the scanning of the ground to identify underground metal parts with extreme precision, the detection is highlighted by an instant modulation of the acoustic signal.
Features
- Lightweight and robust for use on site
- They allow to delimit the edges of the manhole cover
- Great detection depth
- Ergonomic handle
- Excellent value for money
