Geoprobe® GV5 Sonic Head
Geoprobe® GV5 sonic head comes with a 2-year warranty.
Designed and manufactured by Geoprobe®, the 50,000-pound dynamic force has the power to advance up to 12-inch tooling. And with 4,000 ft-lbf at 90 rpm, the 2-speed rotary drive has the torque needed to maintain rotation in tight formations. Comes with a three-year warranty.
The GV5 sonic head includes a centerline side shift function, which moves the head to the side so you can work inside the tool string without moving the mast or re-positioning the machine. This allows the driller to easily access the casing with the dual pivoting winch mast.
An optional coring head and auto drop hammer can be mounted onto the head carrier next to the sonic head. These items can be accessed independently at any time by side shifting over the tool string.
Geoprobe® Rod Handling System
Rod handling system on 8250LS sonic drill rig increases safety for drillers while completing sonic boring.
Video: Sonic Rod Handling System
Reduce fatigue and injury while increasing productivity and safety. Handles large diameter, 5- and 10-foot rods and casing, minimizing heavy lifting. Adjustable angles permit precise head alignment. Pairing with indexing rack creates a nearly hands-free operation without sacrificing drilling performance.
High Speed Coring Head for Sonic
Switching to high speed coring is fast and easy with optional coring mount on the GV5 sonic head.
Video: High-Speed Coring Head for Sonic
The switchover from sonic to high-speed coring is easy, taking less than five minutes in the field.
The optional coring head mounts onto the side of the GV5 sonic head, moving 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.
Also, the high-speed coring head incorporates a side-feed swivel, and is setup to work with our floating subs. The floating subs have 2 inches of travel simplifying make-up with the tool string. Thread options include: AWJ, NWJ, NWL, HWL, or PWL connections.
Dual Winch System
Dual winches on the 8250LS sonic drill rig simplifies sonic boring.
The standard winch on the 8250LS has 100 feet of 5/16-inch cable and has 2,500 lbs. of line pull. The optional secondary winch (1/4-inch cable) is capable of 1,800 lbs. of line pull and has a capacity of 425 feet. It is also equipped with a quick change, which allows you to switch from a hook to an overshot.
14-inch Double Wrench Breakout
Compatible with casing from 2 inches to 14 inches, double wrench breakout offers 9-inches of vertical travel.
With 13,500 ft-lbf of torque, the 14-inch double wrench breakout gets the job done. It is compatible with casing sizes from 2 inches to 14 inches and offers 9 inches of vertical travel.
Adjustable Swing-Arm Control Panel
Dial in speeds, feeds, and pumps precisely while steering clear of spinning rods with adjustable swing arm control panel on 8250LS sonic drill rig.
Position yourself comfortably close to align rods or safely away from spinning tool strings with the adjustable swing arm control panel. It features an intuitive layout that allows the operator to perform multiple tasks effortlessly. Speeds, feeds, and pumps can be precisely dialed in with the electronic controls.
An integrated systems display on the control panel provides real-time monitoring of machine parameters and a suite of built-in diagnostic tools. The control panel features an operator presence bar and emergency stop for added safety. Also included are system safeguards that protect the main engine and hydraulic components when important operational parameters are compromised.
Front and Rear Outriggers (Four Point Stabilization)
Outriggers on 8250LS increase stability during sonic boring.
Front and rear outriggers on the 8250LS are adjustable and allow the operator to help stabilize and level the machine on unlevel terrain.
Head Centerline Side Shift, Extend, Drill Mast Dump, Breakout Vertical Shift, Drill Mast Side-Shift
Sonic boring with 8250LS simplified with drill mast movement.
Eliminate the need to move mast or machine to align with borehole. Works in combination with dual pivoting winch mast to easily access top of casing. Makes optional automatic drop hammer and coring head independently accessible.
The centerline side shift function moves the head side-to-side so you can work inside the diameter of the rod without moving the foot or repositioning the machine.
Not only does the drill mast move fore and aft relative to the track base, it can also be shifted left to right, up and down, and run at angles up to 45 degrees off vertical
Remote Diagnostics
Expert assistance available via remote diagnostics on 8250LS.
Integrated systems display provides real-time analysis and built-in diagnostic tools so our sonic team can remotely troubleshoot. Built-in redundancy on key components means finishing the day and addressing the issue at a convenient time.

“Traditionally to get to 120 feet and build a well at the site was a two-day process. With the sonic we were able to get the well drilled and installed in 12 hours, with zero issues. This ended up saving our client several thousand while keeping waste cost to a minimum!”

Tooling & Accessories
The 4x6 method is a well-established configuration using a 4-inch core barrel overcased with a 6-inch casing. Other sonic configurations follow in this manner with larger inner and outer casing sizes. When telescoping one casing over another, (such as 4x6) it is important to consider the spacing (annulus) between the telescoping casings. Geoprobe® sonic casing is designed so that each incremental casing is sized with bit clearances and annular space in mind.
Video: Geoprobe® 6x8 Sonic Sampling
6x8 sonic sampling provides the operator a larger area to work with than the traditional 4x6 method. The operator can obtain a larger diameter sample if desired, but this casing combination is typically used to provide a larger hole, such as to set a monitoring well. When telescoping one casing over another it is important to consider your main objective to determine sampling size.
The 8x10 sonic sampling system is the largest of our conventional sonic sampling systems. The Geoprobe® sonic casing family has been uniquely designed so that each incremental casing size works efficiently with the next. In this case, you will have the size needed to remove even more material from the subsurface.
Sonic Dual Tube 45 (SDT45) is a unique and versatile sampling system advancing an outer casing and an inner soil sampler simultaneously. The SDT45 sample (3.0 in. diameter) is collected in a clear PVC liner providing a high-quality representative sample. The 4.5-inch outer casing remains in the ground (cased hole) while the sample is retrieved with inner 2.25-inch. probe rods. The system provides optional bits based upon geologic conditions (soils and rock) for more efficient sampling and recovery. The versatile SDT45 system can be used for many applications including, environmental sampling, varying types of well installations, cased hole applications, geotechnical borings, and exploration projects of numerous types.
The Sonic Double Wall 45 (SDW45) System compliments conventional Sonic 4x6 system to obtain critical confirmatory rock or bedrock samples at the end of a boring, whether Sonic 4x6 or SDT45 is used. Used for environmental, geotechnical, mineral explorations, and most projects where 4x6 is used, it can also be used in place of traditional sonic dual tube system when angled drilling is required.
The SP60 Sonic Groundwater Sampler is a packer based, deployable sampling system designed for collecting groundwater samples through Geoprobe® 6-inch casing. The system includes an inflatable packer, 2-inch stainless steel screen, and an inflation manifold assembly. The assembly is commonly deployed inside 6-inch casing with standard 2-inch schedule 40 PVC. The packer is inflated via flexible tubing, inflation valve assembly, and air supply (not included). Manual air pumps or a small air tank are common sources for the compressed air needed to inflate the packer.
Video: Indexing Rack for 10-foot Sonic Tooling
With a few basic movements and one ‘touch’ of the drill stem, sonic tooling can be loaded into the rig’s rod loader, and the machine’s functions take over. The same can be said when tripping rods out of the borehole. The machine-based rod loader lowers the tooling to a position where once again a few basic movements and one ‘touch’ of the casing puts the tool safely back into the indexing rack until it’s needed for the next interval. The rack is adapatable to run 3.5-inch to 10-inch sonic casing in 10-foot lengths.
