WDC Exploration & Wells operates the newest and most powerful high-capacity direct push machines from Geoprobe®.
Model 7730DT This is a high-capacity direct push machine with a durable undercarriage, hollow stem auger capabilities, and a rubber track wide-base platform. The heart of the 7730DT is the powerful GH62 hammer which was designed specifically for direct push applications. Highly productive in both shallow and deep sampling venues. The stronger, wider undercarriage allows the 7730DT to be used on concrete or pavement, and enables the machine to readily negotiate in tight, confining work areas and on offroad, rugged terrain.
