A manual alternative to hydraulic driven machines. Reach tight spots while providing a low cost option to collect soil, soil gas and groundwater samples. Designed for sampling depths less than 20 ft. The small diameter 2 ft. Large Bore sampler is the recommended method to collect soil using the slide hammer but 2 ft. and 3 ft. Macro Core samplers are available. Grab groundwater samples quickly from shallow water tables using 1" rods, expendable points and Geoprobe's stainless steel mini-bailer or peristaltic pump. Choose from 15, 30 or 45 lb hammers.
This powerful little machine was designed specifically to be durable yet as lightweight as possible. At 23 in. wide, 62 in. tall (folded), and weighing less than 425 lb., the 420M can be manually lifted and carried to remote sampling locations. It can also be deployed to hard-to-reach and narrow sampling locations. The 420M is powered by a remote hydraulic power source which easily attaches to the machine or by using the auxiliary hydraulics from other Geoprobe machines.

The 540MT provides extra flexibility other Geoprobe 54-series machines do not. It's great for low overhead situations inside buildings and basements. The probe is telescoping so you can work inside with overhead 8.2 inch ceilings and still collect 4 foot samples using the full capacity of the 54-inch stroke. The power source works outside the building or basement and is independent of the Geoprobe itself. Large soft tires minimizes potential impact to lawns. We provide a special designed enclosed trailer which includes loading and unloading winch, shelving, storage compartments and exhaust vent for the power source. Download E-SPEC SHEET (PDF)...
