Geophysical systems NDE 360 One Platform - Multiple NDE Testsgeo-36 Crosshole/Downhole Seismic ASTM D4428/D4428M-07/D7400-08(DS)Features: Real-time waveform display while testing Thin layers, which are often invisible to surface methods, can be detected with CS/DS investigationsAcquisition and processing software are easy to use, yielding fast and accurate resultsCS method is the most accurate method for determining material properties of rock and soil sitesAccuracy and resolution for the CS test method are constant for all test depths, whereas the accuracy and resolution for the DS surface method decreases with depthSources and receivers can be oriented with inclinometer casing dummy probesP-SV source used in CS tests can impact in the vertical, transverse, and radial directionsCorrelation between CS and Spectral Analysis of Surface Waves (SASW)
