If you already own a JMC Professional Auger with threaded connections, you don't need to invest in a new handle and extensions just to pull a soil core. All you need is this Adapter and your choice of a JMC Soil Sampling Tube.
In fact, if you want to obtain an extremely accurate sample from a particular strata, you will have the best results with this procedure:
- Carve a hole with your auger down to the top of the desired strata.
- Replace the auger head with this adapter and a JMC Sampling Tube.
(We recommend the JMC Zero Contamination Tube for this application.)
- Remove any loose debris inside the hole with a vacuum cleaner.
- Lower the sampling tube into the hole and take your sample.
Tip: A JMC Driveable Auger Handgrip and a PN017 Dead-Blow Mallet (See Related Products List below) will make tube sampling easier. If desired, the hole may be deepened by reinstalling the auger and reentering the same hole.
