Efficient subsurface imaging with tTEM

The tTEM Geoscanner

Revolutionary Groundwater Mapping

The tTEM geoscanner revolutionizes land-based groundwater mapping. It tows by an all-terrain vehicle (ATV) to create high-resolution subsurface layer images. Surveys cover areas from tens to thousands of hectares (2 – 2000 acres), with a depth of investigation ranging from a meter or two below the surface to an impressive 180-200 meters (600 – 650 feet) depending on configuration. 

Unparalleled Coverage and Versatility

The tTEM geoscanner allows surveys along lines or in full 3D, offering comprehensive coverage. It enables detailed imaging of subsurface features, making it invaluable for various applications. Pinpoint new well locations, explore hydrogeological mapping in 3D, and more with the tTEM geoscanner’s exceptional results.

Superior Data Quality

Our tTEM geoscanner leverages advanced electronics, microcontrollers, and computers for maximum potential. It withstands challenging field conditions while delivering high-quality data. The instrument’s craftsmanship and robust design ensure reliability and accuracy in measurements.


Key Technical Details tTEM: 

  • Driving speed: up to 20 km/h (12 miles/h)
  • Depth of investigation: up to 130 m (430 feet) or 180 m (600 feet) depending on configuration
