  • Groundwater Evaluation
  • Structural Geology
  • Mining

    All tools have the ability to record and display results at surface in real time mode as it traverses up the hole.

    Fig 1 Displays a log from which determination of hole condition can be made from surface to end of hole or between certain intervals within the hole.

    Fig 2 After the tool has completed the survey, instant calculations can be made in this case borehole volume.
