Bundled Applications Software:
refraction analysis software (delay time method) from Rimrock Geophysics. Operates when your laptop is connected to the ES-3000
* SeisImager/2D Lite refraction modeling and analysis software (time-term least squares, delay time, and tomographic inversion methods) from OYO.
Operates when your laptop is connected to the ES-3000
and SeisImager/2D Lite are configured for in-field analysis and require connection to ES-3000 seismodule, and a mouse for SeisImager/2D Lite, to operate. Standalone versions available; please contact the factory with your requirements
