To sample below the length of your sampling tube, add extensions between the sampling tube and slide hammer of the JMC Environmentalist's Sub-Soil Probe.
Please Note: The JMC ESP Master Extension splits into two pieces when adding a Regular Extension. (See diagram at right).
Reliable hole and cross pin connections.
First extension must be a JMC Master Extension.
Additional extensions must be JMC Regular Extensions.
Each extension adds 3 feet of sampling depth.
Number of extensions limited only by soil conditions - usually 15 to 21 feet.
The ESP pulls a 3 (or 4) foot long by 0.8 inch diameter sample in one plunge. It captures every sample in a plastic (or stainless steel) liner and can sample to 3 (or 4) feet (30 feet with extensions). 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 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.
