EXI is pleased to announce the addition of the Geometrics 24-channel Geode to our rental inventory! Bundled with its own processing software, the Geode boosts our offering to 
those who are engaged in MASW and SASW seismic acquistion as well as standard refraction and reflection work.
Our friends at Geonics provided a nice tip which will be welcome by those doing VLF surveys in North America. The Northern Colorado Sudden Ionospheric Disturbance Observatory monitors various vlf frequencies and publishes the data at their website:

This will be of help when you are questioning whether a site is up and running or not. We'll maintain a link to them from our web site for your convenience.
