Ground radar looks deeper
An Australian company named Midnight Opals has trialled a new generation of ground penetrating radar that promises good results.
Optimal penetration of traditional GPR technology is realistically about 25 m in dry conditions and sometimes only centimetres in moist heavy conditions, making it virtually useless within the mining industry.
The company, the exclusive licence holder of the latest technology, has reached depths of up to 500 m in dry conditions and up to 100 m in heavy moist soils, which is claimed to make this GPR the most advanced in the world.
It is predicted to become a tool for finding minerals, hydrocarbons and water. It can detect objects, changes in material, cracks and voids and can be used above or below ground.
