"SPHINX" VM-901 PRO Metal Detector The "SPHINX" VM-901 PRO metal detector is designed to locate and determine the depth of underground utilities (manhole covers, valves, pipelines, etc.).
This manhole detector replaces the legendary model of the same name, which has been in production since 1992 with various upgrades and has earned recognition among utility services, telecommunications, and energy companies in Russia, CIS countries, and beyond.
The new model will change your perception of this type of metal detector. The device features fine-tuning capability, allowing it to detect manhole covers at distances of up to 1200 mm (actual performance may vary depending on ground mineralization).
We have also improved the device's protection, enabling operation even in heavy rain.
