The ESP PLUS pulls a 3 (or 4) foot long by 1.2 inch diameter sample in one plunge. It captures every sample in a plastic liner and can sample to 3 (or 4) feet. Sampling tube is driven by a 12.5 pound drop-hammer (or electric hammer) and retrieved with a foot-operated jack.
Assembly fits manual sliding hammer for the JMC Environmentalist's Sub-Soil Probe (0.8 inch diameter sampler). This is the part that rests on the top of the sampling tube that fits up inside the heavy sleeve of the hammer.
