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 Sampling Tube and a JMC ESP Master Extension. Regular extensions connect to each other for additional sampling depth capability.
If you need to gather samples beneath a concrete pad, this carbide bit can drill a hole large enough to allow a ESP Plus Sampling Tube to pass through.
In spite of its name, the Clay Auger will sample the widest variety of soils. Good for most soils between dry sand and wet mud. Fits all threaded connection JMC Professional Auger components.
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.
