GM8000
Modular multichannel GPR mobile mapping system for the subsurface
Interchangeable GPR arrays with high speed dynamic range
The highest density of information, accurately mapped in 3D
Virtually limitless data management and computational power
For those who want to take subsurface mapping to a much bigger scale, Screening Eagle released the new GM8000 Mobile Mapping system for the underground.
The GM8000 is a fully equipped GPR system, designed to be towed by a vehicle. The system consists of Multichannel GPR array sensors and an intuitive app to control the whole system during data acquisition. There are two modules, GX1 and GX2, tailored for near-surface - and deep detection, respectively, to have every scenario covered.
This allows the GM8000 to cope with utility mapping, geophysical or archaeological surveys as well as bridge or pavement analysis projects, with nothing else than a simple click-out and a click-in of the corresponding GPR array module.
