GS One geophone sensor(P/N: ST-10PA) is a type of high precision and low distortion sensor, which is more and more applied in 2D&3D seismic survey and vibration monitoring with a single unit by replacing multi-geophone strings.
With the characteristic of high sensitivity, low distortion, light weight and easy deployment, the ST-10PA geophone sensor is becoming an improved choice compared with conventional 10hz geophones.
