The JMC Pin Ejection Tool removes crosspins quickly and easily from extensions for the JMC Environmentalist's Sub-Soil Probe and the JMC Environmentalist's Sub-Soil Probe Plus.
Prevent hand injuries.
Reduce chances of losing crosspins.
All metal parts nickel-plated to protect against rust and wear.
Here's how the JMC Pin Ejection Tool works:
Step One: Put the extension between the tool's jaws and sqeeze the handgrip. This pushes the pin out far enough to pop the ball plunger out of the pin's groove, but not far enough to let the pin fall to the ground.
Step Two: Use the smaller jaws to grip the protruding pin. Clamp the jaws shut and remove the pin from the extension. To avoid losing the pin, keep the jaws clamped until you're ready to reinsert the pin.
 
 
 
Step Three: After reinserting the pin into the hole, unclamp the jaws and tap the pin into place with the backside of the tool.
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.
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.
Replacement part. Sandwiched between lower end of sampling tube and cutting tip. Directs flow of soil into the liner. Without it, clay samples have a tendency to crumple the plastic liners.
