Redefining drilling for over than 30 years by producing solutions to meet or exceed clients’ needs, the most recent Geoprobe® innovations are advancing the geotechnical industry.

Drillers positioning for increased productivity and profit choose the Geoprobe® 31 series geotechnical drill rigs with innovative centerline head side shift and separate hydraulic circuit for mud pump. The end result – faster, easier, and safer drilling.

Engineered for safe geotechnical drilling in a small footprint on wide tracks, the 3126GT compact geotechnical drill rig nimbly navigates off-road without sacrificing power or versatility.

Incorporating all the same drill mast features while mounted on a truck chassis, the 3100GT also provides full functionality and power for your typical geotechnical projects without the need for a class A/B CDL, aiding ability to quickly advance helpers to drillers.
