This extension lets you sample 3 feet deeper than the length of your sampling tube. (6 feet with a 3 foot tube) If you want to sample deeper than that you will need to purchase one or more JMC ESP Regular Extensions in addition to this extension.
Use our solid tip instead of a cutting tip to plunge to desired depth without filling the sampling tube. Useful for creating small diameter monitoring wells or limiting sample debris.
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.
Aluminum Washer fits manual sliding hammer for the JMC Environmentalist's Sub-Soil Probe PLUS(1.2 inch diameter sampler). Fits between the Threaded Collar(PN163) and the Aluminum Cylinder(PN453). This is the part that rests on the top of the sampling tube.
