Geospace GS-30CT Borehole Geophone
The GS-30CT is a close-tolerance, low-distortion geophone purpose-built for borehole and downhole seismic applications, where matched sensor response across an array is critical for accurate velocity and VSP (vertical seismic profile) data.

About the Geospace GS-30CT Borehole Geophone
The GS-30CT is a close-tolerance, low-distortion geophone purpose-built for borehole and downhole seismic applications, where matched sensor response across an array is critical for accurate velocity and VSP (vertical seismic profile) data.
Its tight manufacturing tolerances reduce inter-element variation, an important factor when multiple geophones are combined into a single borehole string or 3-component downhole package.
