The Classic Soil Probe is a 36" one-piece soil sampler. It has an 12" soil tube and a replaceable, screw-on S-2 Regular Soil Tip. An 8" 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 make this a back save
