Collecting Continuous Soil Samples
In combination with the DT37 soil sampling system, collecting continuous 2-inch diameter soil samples is a common practice.

Installing Prepacks
Geoprobe® 3.75-inch tooling was designed in conjunction with the Geoprobe® 2.0-inch Slim Prepacks to create a more efficient method of installing 2.0-inch Schedule 40 prepacked screen monitoring wells. The 3.75-inch rods have a 3.75-inch OD and an ID of 3 inches. In short, it's an optimal casing combining ease of use for 2.0-inch Slim Prepack installation, minimal borehole size to maintain reasonable penetration rates, and a robust thread design. This durable and robust tooling system can be driven with Geoprobe® percussion hammers.
