Non-destructive exploration is the exploration technology that does not damage the structures

・It can explore all the objects
・It can explore the deep layer (4m or so) from the surface.
・The exploration accuracy is within approximately± 10cm horizontally and ± 10% vertically.
・(Depends on the soil, etc.) Exploration can be carried out without being affected by the structures and high-voltage electrical power lines

We have various models for different exploration objects and depth.
