SEISMIC PRODUCT LISTING

EXI is rapidly expanding the seismic inventory. We currently carry a number of seismographs for both reflection and refraction work. The Geometrics Smartseis units (S12 and S24)are very good for refraction work, but for reflection we would recommend the Geometrics Geode, Strataview (R24)or the Seistronix RAS24's.

If you are contemplating running a surface wave survey, you may use most of the boxes recommended above. However, the EXI Smartseis boxes will not record long enough time samples for passive techniques (REMI).

The Land streamer has proven to be a real time-saver for deploying geophones on SASW surveys. The PEG-40 Weight Drop System is an economically ideal source to get power into the ground when needed.

Our friends at Geovision (www.Geovision.com) have kindly allowed us to use their concise write-up on Surface Wave Techniques for those who need information about this growing field of seismic exploration.
