The AMS 9120-RAP-D PowerProbe machine is a new and improved design for the 9100 series models that allows you to use a UTV style 4x4 or 6x6 to get in remote jobsites for shallow direct push applications with 1.2m (4-foot) DP Extensions. 
This model comes standard with our 90-ft-lb hydraulic hammer to sample in almost any type of soil condition you run in to. 
The AMS 9120-RAP-D can be set up as a quick detach from the UTV machine if you need to Heli-Lift by air into remote locations with or without roads.
