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 JMC Environmental Fate Sampler takes a 6 inch diameter by 2 inch deep sample. Compatible with the JMC Environmentalist Sub-Soil Probe or any hydraulic soil probe, it maximizes recovery of surface applied chemicals on day zero and greatly reduces surface contamination risk to subsequent samples.
Threaded Guide Rod fits manual sliding hammer for both the JMC Environmentalist's Sub-Soil Probe (0.8 inch diameter sampler) and the JMC Environmentalist's Sub-Soil Probe Plus (1.2 inch diameter sampler).
Replacement footpedal for the JMC Environmentalist's Sub-Soil Probe PLUS. Footpedal usually needs replaced when foot-operated jack slips while extracting sampling tube from the ground.
