The Classic Footstep Soil Probe is a 36" one-piece soil core sampler with an added welded-on footstep. This is our most popular soil probe because of its durability, size, and ease of use. It has a 12" soil tube and a replaceable, screw-on regular soil tip. A 5" handle is welded on to the probe for convenience. As a single unit, it's incredibly durable and there's nothing to take apart, so it's easy to grab and go. The 36" soil probe length makes this a back saver when working long hours in the fields and the footstep makes it easy to push into the soil.
