No carrier vehicle to contend with but still the reliable Geoprobe® direct push power you've come to expect. The Model 540MT probe assembly is fabricated from the same components as other 5400 Series machines, and is accompanied by a PortaCo power unit. It's easily maneuvered by two people. When folded, the unit is less than 29 inches (737 mm) high. The rear wheel and handle pivot 360 degrees to deliver the tightest turning radius possible.
