Hand augers can reach depths of up to what?

Explanation:
Hand augmentation depth is limited by how far you can manually twist, push, and pull the tool with a straight, controlable core. For a standard hand auger, the practical maximum depth you can reliably reach and retrieve a clean core is about four feet. Pushing deeper becomes difficult due to reduced leverage, operator fatigue, and the risk of bending the shaft or losing the sample. Deeper sampling would require longer shafts and usually a powered unit or drilling rig, which is why much deeper depths aren’t typical with hand augers. Two feet is feasible, but it doesn’t represent the maximum you can achieve with a standard hand auger, while six or eight feet would generally need different equipment.
