   SmartSeis ST Seismograph ã   Find bedrock, depth-to-water, faults; determine V s  for IBC site classification ã   Ideal for engineering, construction, road building, and teaching ã   Completely integrated and rugged system with built-in PC, daylight-visible color LCD, keypad, and printer ã   Provides in-field answers for you and your client    bundled refraction data analysis software picks first arrivals and calculates final cross-section    optional surface wave software picks dispersion curve and calculates shear-wave velocity ã   Best value in a professional, all-around seismograph Looking for a quick way to find depth to bedrock? Want to determine the shear-wave velocity (V s ) for IBC V s 30 site classification? Need an economically-priced integrated instrument? Look no further! If you are a geoscientist doing teaching or research, or need a basic exploration seismograph to find bedrock or determine IBC V s 30 site class, the next generation SmartSeis ST is for you. The SmartSeis ST is an integrated seismic exploration system with a built-in ruggedized PC, daylight-visible LCD, keypad, and high-resolution plotter. Use the plotter to print and show your client or students results right in the field. The SmartSeis ST system comes standard with the data analysis software you need to do comprehensive refraction surveys. As an option, you can add the capability to analyze surface wave data to determine V s . Geometrics also offers special pricing for multiple licenses of data analysis software so field crews or students can have their own copies. The SmartSeis ST is backed by Geometrics, now in our 41 st  year of prompt and knowledgeable customer support. Our seismographs and the SeisImager suite of software are also available for rent. SeisImager/2D Lite refraction data analysis software lets you model and plan your survey beforehand. Pick first breaks and output cross-sections by three different analysis methods. SeisImager/SW surface wave data analysis software calculates dispersion curves from active and passive source (microtremor) data records. The dispersion curves are then used to determine V s .   SmartSeis ST Seismograph Specifications: Configurations:  12, 16, or 24 channels configured as an integrated unit in weather-resistant container with built-in LCD, keypad, and ruggedized PC running Windows   XP Home.
