What GeoStuff does

GeoStuff is a privately-held manufacturer of specialized shallow seismic survey equipment, founded in 1990 by Doug Crice and headquartered in Lincoln, California. The company designs and sells instruments used by geophysicists, geotechnical engineers, and environmental consultants for near-surface subsurface investigations, including earthquake site response studies, rippability assessments, depth-to-bedrock mapping, groundwater exploration, and shear wave velocity surveys. With a headcount of 1-10 employees, the firm operates as a focused, founder-led specialist in a narrow segment of the broader geophysical instrumentation market.

The product portfolio centers on the AnySeis cableless seismic acquisition system, the BHG-2 through BHG-5 series of wall-lock borehole geophones (with the BHG-5 featuring a digital 32-bit A/D converter array), the LS-1 Seismic Land Streamer for rapid surface coverage, hammer/trigger switches compatible with accelerated weight drop sources, borehole extenders, and dedicated controllers (BHGC-1, BHGC-4, BHGC-5). Notable technical characteristics include the cableless architecture of AnySeis, which removes the cable-handling bottleneck typical of conventional seismic spreads, and the wall-locking mechanism on borehole geophones that enables deployment without external clamping hardware. Products are sold individually and as bundled systems to professional end users.

GeoStuff operates a direct sales model via email and phone order, with products shipped globally. The company does not publish list pricing, has no disclosed external funding rounds, and shows no signs of venture or private equity involvement. Revenue mechanics appear to consist of unit sales of higher-margin specialty hardware to a diversified base of professional users, with named customers spanning equipment manufacturers (Geometrics Inc.), soil and groundwater consultants (Schwartz Soil Technical Inc.), and engineering firms (BGC Engineering). The 35+ year operational history and diversified customer base indicate a stable, capital-light business model with no major working capital or platform dependencies.

Core offering

GeoStuff designs, builds, and sells specialized hardware for near-surface (shallow) geophysical seismic surveys. Its catalog spans the AnySeis™ cableless acquisition system, a BHG family of analog and digital wall-lock borehole geophones, the LS-1 land streamer, hammer/trigger switches, borehole extenders, and dedicated controllers. These instruments are sold directly to geophysicists and engineering firms conducting earthquake site response, rippability, depth-to-bedrock, groundwater, MASW, shear wave, and shallow reflection surveys.

Product overview

GeoStuff offers a portfolio of near-surface seismic exploration products centered on cableless systems and specialized geophones. The flagship AnySeis™ cableless seismic system replaces conventional spread cables with individual modules containing geophones, A/D converters, and telemetry electronics. This integrates with the LS-1 Seismic Land Streamer for towed-array surveys. The borehole geophone line (BHG-2, BHG-3, BHG-4, BHG-5) provides wall-lock downhole and crosshole survey solutions ranging from analog 3-component tools to digital multi-tool arrays with compass orientation. Supporting accessories include hammer switches and specialized controllers (BHGC-1, BHGC-4, BHGC-5) that route signals to conventional seismographs or directly to laptops. The product architecture allows customers to purchase individual components (geophones, streamers) or complete turnkey systems.

Products and services

• AnySeis™ Cableless Seismic System A cableless exploration seismic acquisition system where complete channels (geophone, A/D converter, telemetry) are built into individual modules that clamp onto a standard 2-conductor wire. Modules are configured in any spacing, geometry, and channel count; data is digitized at the geophone for immunity from electrical interference. Targets geophysicists and engineering firms conducting near-surface surveys.
• BHG-2 Wall-Lock Borehole Geophone The original wall-lock borehole geophone with a 3-component (X-Y-Z) geophone and a robust DC motor-driven clamping mechanism that uses no rubber bladders. Designed for downhole and crosshole shear wave studies.
• BHG-3 Wall-Lock Borehole Geophone Wall-lock borehole geophone with three geophone elements plus a fluxgate compass and servo mechanism that automatically rotates the horizontal sensors to align with the energy source azimuth. Intended for downhole and crosshole shear wave surveys requiring orientation.
• BHG-4 Slimhole Borehole Geophone Small-diameter wall-lock borehole geophone designed to fit in 1.5-inch (38 mm) tubes, with overall diameter under 2 inches, for tight borehole applications that cannot accommodate standard geophones.
• BHG-5 Digital Wall-Lock Borehole Geophone Digital wall-lock borehole geophone with an internal 32-bit A/D converter that digitizes signals from three sensors in the tool and includes a digital compass for azimuthal orientation. Multiple BHG-5 tools can be daisy-chained into arrays of up to 24 geophones that connect directly to a laptop without a separate seismograph.
• LS-1 Seismic Land Streamer A geophone array designed to be towed along the ground by hand or vehicle for high-productivity seismic surveys. Features a hardened steel cast base plate with tripod support, Kevlar-reinforced tow webbing (2200 kg tensile strength), and adjustable geophone spacing for various survey configurations; integrates with the AnySeis system.
• Hammer/Trigger Switch Rugged replacement hammer/trigger switch designed to withstand the repetitive pounding of seismic surveys. Available with mating connectors for most popular seismic systems and also compatible with accelerated weight drops; user testimonials report thousands of hammer blows without failures or timing issues.
• Borehole Extenders Mechanical extenders available in different sizes for use in larger cased boreholes, designed to improve the rotational stability of wall-lock geophone tools deployed in oversize holes.
• BHGC-1 Analog Controller Controller for operating a single 3-component borehole geophone, containing an internal 24 V rechargeable battery sufficient for several weeks of surveys; routes the analog signal to a conventional seismograph.
• BHGC-4 Analog Controller Controller capable of operating up to four borehole geophones, with an internal 24 V rechargeable battery for extended field use; routes analog signals from each tool to the user's seismograph.
• BHGC-5 Digital Controller Digital controller that operates BHG-5 borehole geophones and routes their digital signals directly to a laptop, eliminating the need for a conventional seismograph. Additional controllers can be daisy-chained for arrays exceeding 24 geophones.
