Geoprobe 7822DT

Roddy Qualls Environmental Drilling

The 7822DT is track-mounted, highly maneuverable (remote controlled) and is capable of drilling on a variety of surfaces, terrains, and in locations not readily accessible to truck-mounted drilling equipment.  This rig is perfect for limited access and low clearance areas.  Don't be fooled by the size, this drilling rig can spin hollow-stem augers like the big boys!  The winch and mast also allow for extra safety measures when drilling.  All of these components equal a drilling machine that can take on many unique field applications.
