If you already own a JMC Quick-Connect Professional Auger, 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:

1. Carve a hole with your auger down to the top of the desired strata.
    
2. Replace the auger head with this adapter and a JMC Sampling Tube.
         (We recommend the JMC Zero Contamination Tube for this application.)
    
3. Remove any loose debris inside the hole with a vacuum cleaner.
    
4. 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.
