Big Sonic Power

Geoprobe Systems® engineers and manufacturers both full-size and mid-size rotary sonic drilling rigs and machines with powerful sonic heads (50K dynamic force). They deliver big sonic power to advance large diameter tools to greater depths and provide the control necessary to complete complex holes. Continuous samples can be collected in multiple geologic formations, including core sampling in consolidated materials (rock) and soil sampling in unconsolidated formations such as glacial till and backfill rubble.

Sonic Rig Features

Powerful GV5 Sonic Head

Geoprobe® GV5 Sonic Head on the Geoprobe® 8150LS Sonic Drilling Rig

The power of Geoprobe® sonic drilling rigs comes from the GV5 sonic head. The 50,000 lbs. of dynamic force has the power to advance up to 12-inch diameter tooling. And with 4,000 lbf at 90 rpm, the 2-speed rotation drive has the torque needed to maintain rotation in tight formations.

Safe Operation

Swing arm control panel on the Geoprobe® 8150LS Sonic Drilling Rig

Rig operators benefit from two main safety features of the Sonic Rigs. One is the adjustable, easy-to-use control system which features an operator presence bar and emergency stop for operator safety. Multiple emergency stops are located around the rig and on the wireless and tethered remote systems.

Efficient Sampling

Head centerline side shift on the Geoprobe® 8150LS Sonic Drilling Rig

The GV5 sonic head features a centerline side-shift function which moves the head side-to-side so you can work the inside diameter of the rod without moving the foot or without re-positioning the machine. This allows the operator to easily and safely access the dual pivoting winch mast system.

High Speed Coring

High speed coring head on the Geoprobe® 8150LS Sonic Drilling Rig

The optional coring head mounts onto the side of the GV5 sonic head. It moves into place by side shifting the head. The coring head is capable of 800 rpm with 540 ft-lbs of torque in forward and 720 ft-lbs of torque in reverse for breaking tool joints.

Accurate & Successful Results

Geoprobe® Weighted Wireline Sonic Soil Sampling System on the Geoprobe® 8150LS Sonic Drilling Rig

With Geoprobe® Sonic Drilling Rigs, you can produce more cost-effective holes while retrieving more accurate subsurface data. You can sample multiple geologic formations, including consolidated materials (rock), glacial till, and backfill rubble.

Service & Support

Remote diagnostics on the Geoprobe® 8150LS Sonic Drilling Rig

The cost-effective Geoprobe® sonic package is inclusive: drilling rig, sonic head, tooling, training, and service. Everything is designed, produced, and supported by Team Geoprobe®. Our rigs include wireless remote diagnostics for real-time systems monitoring by Geoprobe® service and engineering.


We continue to design and manufacture our own Sonic product line which offers 8 x 10, 6 x 8, and 4 x 6 sampling and our exclusive dual tube sonic sampling and weighted wireline tools. Geoprobe® is the only manufacturing company that offers different sampling methods … in collection bags or liners … in the industry. With our sonic liner collection system, you can view the accurate depths from which a sample is pulled.

We invest in state-of-the-art manufacturing processes to produce the widest array of sonic bits and sampling systems available for the sonic market, from conventional telescoping soil coring to dual tubing and face flush bits for rock coring. Our sonic tooling is engineered for ease of makeup and breakout with no galling or deforming in the thread area.

Our sonic owners know with their rig purchase comes comprehensive training for rig operation and maintenance, and one-on-one, individual training for the use of tooling and the rig. We also provide the best sonic service support in the drilling industry. When our customers call with a need, we respond.
