Dual wall CoreBarell sampling with SonicSampDrill

Please view this movie to see the our CompactRotoSonic at work in a stone querry in germany sampling in rock. This querry has been choosen to test our latest tooling developments in its extreme difficult geology. The dual wall core barrel system allows our clients to sample in mixed or solid materials allowing to flush through an annular to cool the bit and to get rid of the cuttings, without the medium (water, air or mud) contact the sample. E.g. sampling for alluvial gold in sand with large boulders you will have 100%recovery of the sands and the boulders! Our dual wall core barrels are available in 65mm/2,5" sample (telescopes through the 5,5" casing) or 89mm/3,5" There are several types of bits available for different geologies Larger diameters have been supplied as custom made solutions.
