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.
Extremely durable aluminum case designed to withstand airline baggage handling and other abuses. Case protects either size JMC Environmentalist's Sub-SoilProbe with extensions, liners, and extra parts.
Replacement part. Sandwiched between lower end of sampling tube and cutting tip. Directs flow of soil into the liner. Without it, clay samples have a tendency to crumple the plastic liners.
