The PS-8R consists of a source and an 8-transducer receiver probe, which can be placed in the same or in different holes.
The PS-8R can be used for reflection and tomographic studies.
Both dry and water-filled holes, of arbitrary inclination can be used. The units clamp hydraulically to holes with diameters of 56 to 100 mm.
The source generates time-coded pulse sequences, which are summed to produce high dynamics broad-band records.
The PS-8R is capable of imaging single fractures at a distance of 10 to 20 m, by emitting and recording frequencies up to 60 kHz.
