Geode Exploration Seismograph

Available for rent

The Geode Exploration Seismograph is the most popular engineering seismograph in the world, used by both academics and geophysical professionals. The Geode is a versatile and flexible seismograph, small and lightweight enough to pack into your suitcase, yet easily expandable if needed for full-scale 2D and 3D surveys via our intelligently designed distributed architecture. Use the Geode for reflection, refraction, MASW/MAM, or tomography surveys, as well as for more niche use cases such as earthquake, quarry blasts, or heavy equipment monitoring. The Geode can also easily handle marine profiling and continuous recording!


  • Versatile Seismic Recorder: Petroleum exploration and monitoring, engineering studies, depth to bedrock, fault and fracture location, hydrologic investigations, research and teaching.
  • Reflection: Suitable for shallow reflection, deep reflection, 2-D and 3-D surveys
  • Refraction: Comes with built-in first break picking and analysis
  • Marine Surveys: Very fast time between shots, real-time single-trace gathers, gun monitoring, noise snapshots, tape swapping for 24/7 operation.
  • Sub-bottom Profiling: Works with boomers, sparkers, bubble-pulse sources or air guns
  • 4-D Time Lapse Surveys: Weather-proof Geodes can be left in place or redeployed easily for accurate repeat surveys
  • Earthquake Monitoring: Uses STA/LTA type algorithm to trigger on incoming data stream, synchronizes with GPS clock
  • Continuous Recording: Continuous mode plus GPS synchronization for blast and vibration monitoring, general industrial applications.
  • MASW: UBC Vs30/ IBC Vs100 Site Classification, microzonation studies (H/V method), foundational engineering
