420M

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 (sold separately) which easily attaches to the machine or by using the auxiliary hydraulics from other Geoprobe^® machines.
