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.
• Minimize connect and disconnect time with the JMC Pin Ejection Tool.
