About the Sercel SG-5 Geophone
The SG-5 is a high-sensitivity 5 Hz geophone widely used with Sercel's 428XL and other land acquisition systems, offering low distortion and a wide operating temperature range for demanding field environments.
Its low natural frequency makes it well suited to lower-frequency reflection and refraction work where higher-frequency geophones would attenuate the signal of interest.
