SG-10 High Performance Geophone Sensor<br />
SG-10<br />
The SG-10 was developed utilizing rare-earth magnet technology<br />
to achieve very low distortion and the highest tilt tolerance in the<br />
industry.<br />
This technology, coupled with a specifi c magnetic geometry,<br />
results in one of the most advanced geophones in the seismic<br />
industry.<br />
