BHG

Durable detector locates large ferrous metal objects by being lowered into drilled boring holes.

If you don’t want to miss the presence of any ferrous metal in the ground, you can rely on the Bore Hole Gradiometer (BHG). Featuring two sensors, it works similarly to a magnetic locator and can even be used in water, making it ideal for construction companies.
