The borehole seismic array with three-component clamping geophone modules is designed for multiwave crosshole seismic testing. The number of modules on the cable can vary from 1 to 8. The interval between modules is determined by the Customer.

As sensor elements, three normally oriented geophones with a natural frequency of 12.5 Hz are used in each module. The module clamping is achieved by a passive flat spring. Lowering the cable into the borehole is conducted through the load fixed on the end of it.

The use of array with clamping modules along with shear wave source SHock and power supply Jack allows multiwave observations with registration of transverse (S-) waves at distances up to 30 m.

The geophone array can be supplied on a reel with slip ring, which allows to leave the equipment plugged into it while winding and unwinding the cable.
