Description

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!

Use your laptop to view, record and even process your data using our software like SeisImager/2D-STD. You can connect Geodes together to build systems of over 1,000 channels. Geodes are shock-proof, dust-proof, submersible and able to withstand extreme temperatures. Engineered to last, we confidently offer a 3-year warranty for each new Geode sold, an industry leading offer.
