During augering operations, the DH100 Automatic Drop Hammer easily and quickly swings away and can be secured from the field technician’s work area.  The drop hammer is mounted on a Geoprobe 7730DT machine.	Ryan Kejr, Project Engineer, uses an in inhouse training session to explain setting the drop height of the DH100 Auto Drop Hammer.	Environmental Field Services in Westfield, IN, enjoys access to many confining spaces, including an athletic club in Indianapolis.
