Custom-designed for and installed in one's pickup truck or UTV, the DFP Soil Probe System is designed to deliver precise soil samples with every probe, its margin of error reportedly shown to be less than 5%. The sampling procedure is carried out entirely in-cab, with the probe descends through the chassis floor, allowing the driver to draw, then process each sample while in the vehicle's seat. The system includes numerous options, each customizable to the user's vehicle and specific needs. Among those option are stainless-steel slotted or heavy-duty aluminum probes; various-size tips; single- or double-stage hydraulic cylinders: electric-, manual-, or hydraulic-directional valve control; electric-, gas engine-, or clutch pump-driven hydraulic power unit; soil sampling navigation system; soil compaction measuring kit; and core cutter tool.
