Remove cutting tips easily from JMC Environmentalist's Sub-Soil Probe (and Sub-Soil Probe Plus) Sampling tubes! Use one wrench to lock tightly around your sampling tube and another to clamp onto your cutting tip. With two comfortable handgrips, you can unscrew even the most stubborn connection.
The ESP pulls a 3 (or 4) foot long by 0.8 inch diameter sample in one plunge. It captures every sample in a plastic (or stainless steel) liner and can sample to 3 (or 4) feet (30 feet with extensions). Sampling tube is driven by a 12.5 pound drop-hammer (or electric hammer) and retrieved with a foot-operated jack.
