Professional Underground Water Detector UK: 100m Depth Geoelectric System

Before investing in drilling equipment or excavation work, accurate subsurface data is essential. The OKM GeoSeeker Mini is a precision geoelectrical surveying system developed to identify underground water sources and hidden cavities at depths of up to 100 metres.

By analysing soil resistivity and converting measurements into clear 2D visual scans, it gives landowners, engineers and contractors reliable insight into what lies beneath the surface.

Detect Underground Water Before You Drill

The GeoSeeker Mini uses a geoelectrical measurement method based on the Schlumberger procedure.

By measuring soil resistivity, it can identify:

Fresh water deposits
Drinking water sources
Water-bearing gravel
Groundwater levels
Underground cavities

This allows you to reduce drilling risk and make informed excavation decisions.

100 Metre Detection Depth Capability

Customers using this geoelectric water detector have reported successful water detection down to 100 metres (328 ft) depth.

Depth depends on soil structure and moisture content, but this level of capability makes it one of the most powerful compact underground water detection systems available in the UK market.
