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.
This extension lets you sample three feet deeper provided you have a ESP Plus Sampling Tube and a JMC ESP Plus Master Extension. Regular extensions connect to each other for additional sampling depth capability.
Already have a Bosch 11316 Percussion Hammer, 11245 Rotary Hammer, or Bosch RH1255VC Rotary Hammer? Then all you need is this adapter for your JMC Environmentalist's Sub-Soil Probe.
Lighter weight and more compact case for auger kits containing 34 inch extensions. Will not fit 45 inch extensions. Includes two 12 inch crescent wrenches.
