T&A Survey's TISA 3D Borehole Radar will be the first technique to perform 3D ground penetrating radar measurements from a single borehole. In addition, TISA 3D will be able to penetrate deeper into the surroundings of a borehole other than existing geophysical borehole survey tools currently available. Recently, T&A has upgraded this system. The new TISA 3D has improved a lot compared to the 3D BHR.
