Built-in steps allow for additional pressure to be exerted while driving soil probes into the soil. They are available in one or two-piece models. The two-piece model includes a 10" Rubber-Gripped Cross Handle. The same handle is welded to the one-piece model. Both step probes have an outer diameter of 7/8" and cut a 5/8" X 12" soil core. They are constructed of nickel-plated and/or powder coated chromoly that have heat-treated tips.
