It is one kind of geophone applied for Three Component(3C) seismic prospecting. The level and rotation sense are adjustable. With features of robust, light weight and convenient for field operation. Horizontal component axial of the two transversal wave geophones are indicated with arrow on top of the case. Moreover, practical operating state of the geophone will be showed by round level bubble mounted.3Cgeophones is used for multi-component seismic exploration, , and it is widely used to survey highway, bridge, mineral, geophysical and geological test and data acquisition. The 3C Geophone available for the following types:

3C Geophone 1Hz
