The Group's principal activity is developing laser recovery units. The product is a diamond sorting machine which identifies and automatically extracts diamonds from diamond bearing gravel. It uses a technology based on the use of red lasers and a computerised optical recognition technique which automatically detects diamonds from run of mine material by identifying the wavelength shift, known as the Raman shift. Diamonds identified by the laser detection system are then automatically extracted by pneumatic jets into a safe which can only be accessed by authorised personnel.
