{"title":"Commercial Equipment","description":"\u003cp\u003eA 3D ground scanner is a different class of instrument from a conventional metal detector. Instead of a single beep over a shallow target, these systems take readings across a grid and build a 3D image of what's beneath the surface, distinguishing metal objects, cavities, voids, and structures at depths far beyond a standard coil. They're the tools professional treasure hunters, archaeologists, and survey crews use when depth and imaging matter. We carry the leading lines (OKM's 3D ground-scan and long-range systems, the Nokta Invenio imaging detector, and Tero Vido and Groundtech scanners) as an authorized dealer, with expert support for spec'ing the right system.\u003c\/p\u003e\n\u003cnav aria-label=\"Shop 3D ground scanners by brand and detection method, plus related categories\"\u003e\n\u003cp\u003e\u003cstrong\u003eQuick Links:\u003c\/strong\u003e \u003ca title=\"OKM 3D Ground Scanners\" href=\"\/collections\/okm\"\u003eOKM\u003c\/a\u003e | \u003ca title=\"GroundTech 3D Ground Scanners and Detectors\" href=\"\/collections\/groundtech\"\u003eGroundtech\u003c\/a\u003e | \u003ca title=\"Nokta Invenio Imaging Detector\" href=\"\/collections\/nokta-invenio\"\u003eNokta Invenio\u003c\/a\u003e | \u003ca title=\"Tero Vido 3D Scanners\" href=\"\/collections\/tero-vido\"\u003eTero Vido\u003c\/a\u003e | \u003ca title=\"All Metal Detectors\" href=\"\/collections\/metal-detectors\"\u003eAll Metal Detectors\u003c\/a\u003e | \u003ca title=\"Gold Prospecting Metal Detectors\" href=\"\/collections\/gold-detectors\"\u003eGold Detectors\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eShop by Detection Method:\u003c\/strong\u003e \u003ca title=\"All 3D Ground Scanners \u0026amp; Imaging Detectors\" href=\"\/collections\/commercial-equipment\"\u003eAll\u003c\/a\u003e | \u003ca title=\"3D Ground Imaging Scanners\" href=\"\/collections\/commercial-equipment\/3d-ground-imaging\"\u003e3D Ground Imaging\u003c\/a\u003e | \u003ca title=\"Water \u0026amp; Cavity Detectors\" href=\"\/collections\/commercial-equipment\/water-cavity\"\u003eWater \u0026amp; Cavity\u003c\/a\u003e | \u003ca title=\"Magnetometer Detectors\" href=\"\/collections\/commercial-equipment\/magnetometer\"\u003eMagnetometer\u003c\/a\u003e\u003c\/p\u003e\n\u003c\/nav\u003e","products":[{"product_id":"nokta-invenio-pro-smart-metal-detector-and-3d-imaging-system-open-box","title":"Open Box Nokta Invenio Pro 3D Metal Detector with Imaging","description":"\u003cp\u003eAn open box \u003ca href=\"\/collections\/nokta-invenio\"\u003eNokta Invenio Pro\u003c\/a\u003e is the full Invenio Pro package at a reduced price, with the full 2-year Nokta warranty.

Scan the area in a steady pattern and the system combines the position data with the detector's responses to draw a graphical representation. Technique matters: Nokta says the coil must stay parallel to the ground, with a recommended sensor height of 30 to 50 cm (12 to 20 inch). Uneven movement or coil height will skew the result.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003e3D imaging:\u003c\/strong\u003e on an old property where records suggest a large metal container is buried, the graphs may suggest its approximate location and dimensions and help you decide where further investigation is justified.

Nokta says the Artificial Neural Network enables the device to provide superior shape extraction; we read that as better drawings from the detection data, not as identification of what is buried. You can save 3D graphs and screenshots and transfer them to a PC, and vibration can signal a target.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eBatteries:\u003c\/strong\u003e the shaft and the system box run on separate batteries.

We use the small coil for detailed searching, the medium coil as the compromise and the largest for coverage and larger targets.

The Jeohunter's graphical functions give more information on certain targets.

The T21 has no display: it works in LED mode, with a power LED and audio, for confined spaces where the larger coils will not fit. Audio is polyphonic on all three coils, noise canceling and threshold are automatic, and sensitivity and ground balance are set manually.\u003c\/p\u003e\n\n\u003cp\u003eThe T100 is a large coil, and Nokta says it can be carried by two persons for a sweep across open ground. Nokta lists the system at 2400 g (5.3 lb) with the T21, 2600 g (5.7 lb) with the T44 and 8450 g (18.6 lb) with the T100. The lithium polymer battery lasts 4 to 6 hours per charge in Nokta's manual, so on a long survey day we would plan charging around the car charger.\u003c\/p\u003e\n\n\u003ch2\u003eWhich Jeohunter 3D coil to use\u003c\/h2\u003e\n\n\u003cp\u003e\u003cstrong\u003eT21, 21 x 31.5 cm (about 8.3 x 12.4 inch):\u003c\/strong\u003e for conventional searching and smaller targets, with manageable coverage in an area with scattered metal.

Instead of relying only on audio and a target ID number, it combines positional tracking with graphical processing to build a representation of what it detected. We think that suits customers investigating larger buried metal objects, historical sites and possible underground anomalies. One point we want to be clear about: the Invenio does not photograph buried objects. Its images are generated from detection data.\u003c\/p\u003e\n\n\u003ch2\u003eHow the Invenio builds its images\u003c\/h2\u003e\n\n\u003cp\u003e\u003cstrong\u003eIPTU sensor:\u003c\/strong\u003e the Integrated Positional Tracking Unit follows the coil's left-right and forward-back movement and its height above the ground. Picture a suspected buried metal container. You scan the area in a steady pattern, and the system combines the position data with the detector's responses to draw a graphical representation. Technique matters: Nokta says the coil must stay parallel to the ground, with a recommended sensor height of 30 to 50 cm (12 to 20 inch). Uneven movement or coil height will skew the result.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003e3D imaging:\u003c\/strong\u003e on an old property where records suggest a large metal object is buried, the graphs can help you decide where further investigation is justified. They cannot give the exact shape, composition or identity of every object; the result is an estimate built from detector signals.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eGround Anomaly and Cavity mode:\u003c\/strong\u003e designed to help identify certain ground anomalies, such as a void or disturbed ground. A cavity indication is not proof of a tunnel, a chamber or buried treasure; ground conditions and other factors can produce misleading results. The Invenio is no substitute for a professional geophysical survey or an excavation safety assessment.\u003c\/p\u003e\n\n\u003ch2\u003eAbout the Nokta Invenio Standard\u003c\/h2\u003e\n\n\u003cp\u003eThe shaft and the system box talk to each other over a 2.4 GHz wireless connection, and the system box carries a 7 inch, 800 x 480 TFT screen with a backlight, plus an LED flashlight for the scan area. Nokta says the Artificial Neural Network enables the device to provide superior shape extraction; we read that as better drawings from the detection data, not as identification of what is buried. You can save 3D graphs and screenshots and transfer them to a PC, vibration can signal a target, Nokta delivers firmware updates over USB from a PC, and the menus come in 17 languages.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eBatteries:\u003c\/strong\u003e the shaft and the system box run on separate batteries. Nokta gives the shaft a 7.4 V, 5400 mAh battery for about 9 hours and the system box a 7.4 V, 5500 mAh battery for about 5 hours; each takes about 2 hours to charge.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWater:\u003c\/strong\u003e Nokta says not to immerse the device or its accessories in water, except for the search coil and the IPTU sensor, so keep the system box and shaft dry. The waterproof (IP67) hard transport case protects the whole system between sites.\u003c\/p\u003e\n\n\u003ch2\u003eSettings and coils that matter on the Invenio Standard\u003c\/h2\u003e\n\n\u003cp\u003e\u003cstrong\u003e14 kHz:\u003c\/strong\u003e the Invenio Standard works at 14 kHz only. We see that as a practical general-purpose VLF frequency with a balanced response across target sizes. The selectable 5 and 20 kHz frequencies are on the \u003ca href=\"\/products\/nokta-invenio-pro-smart-metal-detector-and-3d-imaging-system\"\u003eInvenio Pro\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCoils:\u003c\/strong\u003e we use the INV28 (28 x 18 cm, about 11 x 7 inch) when maneuverability and detailed searching matter. The INV40 (40 x 35 cm, about 15.7 x 13.8 inch) suits broad areas and potentially larger buried objects, but it is not automatically better on small targets.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eModes:\u003c\/strong\u003e three motion modes (All Metal, Fast and Deep) and three non-motion modes (Basic, Expert, and Ground Anomaly and Cavity).

The core imaging concept is the same on both models.\u003c\/p\u003e\n\n\u003ch2\u003eOne mistake to avoid with the Nokta Invenio Standard\u003c\/h2\u003e\n\n\u003cp\u003eAssuming a graphical image identifies buried treasure.

Picture a suspected buried metal container. You scan the area in a steady pattern, and the system combines the position data with the detector's responses to draw a graphical representation. Technique matters: Nokta says the coil must stay parallel to the ground, with a recommended sensor height of 30 to 50 cm (12 to 20 inch). Uneven movement or coil height will skew the result.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003e3D imaging:\u003c\/strong\u003e on an old property where records suggest a large metal object is buried, the graphs can help you decide where further investigation is justified.

A cavity indication is not proof of a tunnel, a chamber or buried treasure; ground conditions and other factors can produce misleading results. The Invenio is no substitute for a professional geophysical survey or an excavation safety assessment.\u003c\/p\u003e\n\n\u003ch2\u003eAbout the Nokta Invenio Pro\u003c\/h2\u003e\n\n\u003cp\u003eThe shaft and the system box talk to each other over a 2.4 GHz wireless connection, and the system box carries a 7 inch, 800 x 480 TFT screen with a backlight, plus an LED flashlight for the scan area. Nokta says the Artificial Neural Network enables the device to provide superior shape extraction; we read that as better drawings from the detection data, not as identification of what is buried. You can save 3D graphs and screenshots and transfer them to a PC, vibration can signal a target, Nokta delivers firmware updates over USB from a PC, and the menus come in 17 languages.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eBatteries:\u003c\/strong\u003e the shaft and the system box run on separate batteries. Nokta gives the shaft a 7.4 V, 5400 mAh battery for about 9 hours and the system box a 7.4 V, 5500 mAh battery for about 5 hours, and the Pro adds a spare system box battery; the shaft and system box batteries each take about 2 hours to charge, and the spare about 4 hours.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWater:\u003c\/strong\u003e Nokta says not to immerse the device or its accessories in water, except for the search coil and the IPTU sensor, so keep the system box and shaft dry.

We use the small coil for detailed searching, the medium coil as the compromise and the largest for coverage and larger targets. Picture a broad historical site where larger buried objects may be present: the INV56 covers more ground and may help on certain larger or deeper targets. It is not the coil for small objects or heavily contaminated ground.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eExtra battery:\u003c\/strong\u003e the spare system box battery in the Pro package is good for extended scanning sessions.

What interests us about it is that it combines different investigation methods for customers searching larger areas and suspected underground anomalies. Picture a large historical property where you have only a general idea of where a buried object or structure could be: the Delta Ranger gives you methods for a preliminary look and methods for more focused searching. We would recommend it to customers interested in specialized exploration methods who understand the need for independent verification.\u003c\/p\u003e\n\n\u003ch2\u003eThe six operating modes on the OKM Delta Ranger\u003c\/h2\u003e\n\n\u003cp\u003eEach mode switches on when its probe is connected to the control unit.\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBionic Stream (Long-Range Probe):\u003c\/strong\u003e OKM describes it for detecting gold objects, including recently buried ones. You calibrate it with your palm and fingers on the handle electrodes, scan side to side and up and down, and confirm with a control scan from a different direction, about 25 to 500 m (80 to 1,600 ft) from your first spot. Sound, vibration and flashing crosshairs signal a hit.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIonic Stream (Long-Range Probe):\u003c\/strong\u003e OKM describes it for gold objects that have been buried for a long time.

Those are not equivalent forms of evidence.\u003c\/p\u003e\n\n\u003cp\u003eOKM describes Bionic Stream and Ionic Stream as long-range modes for gold. We do not present them as independently proven to locate gold or treasure at specific distances; claims involving long-range gold identification need controlled, blinded testing before they can be treated as established performance. In the same way, OKM gives 3D Ground Scan a depth of down to 18 m (60 ft) on its product page, and we read that as a manufacturer-described capability, not independently demonstrated detection performance.\u003c\/p\u003e\n\n\u003ch2\u003eHow we would follow up an indication\u003c\/h2\u003e\n\n\u003cp\u003eIf a preliminary indication points to an area of interest, we would encourage a structured follow-up survey: clear surface iron with the Magnetometer, then lay out a 3D Ground Scan field over the area. A single directional indication is not proof of a buried object. OKM recommends its Default scan settings for entry-level users and slightly sloping terrain, zigzag lines for advanced users on flat terrain, and manual impulses for rough terrain, and notes that the fewer small metal items are in the soil, the deeper 3D Ground Scan can detect targets.\u003c\/p\u003e\n\n\u003ch2\u003eOne mistake to avoid with the Delta Ranger\u003c\/h2\u003e\n\n\u003cp\u003eThe biggest mistake is assuming that an indicated direction proves that a valuable metal deposit exists. Another is assuming that a graphical anomaly establishes the identity of a buried object.\u003c\/p\u003e\n\n\u003ch2\u003eUsing the Delta Ranger in the field\u003c\/h2\u003e\n\n\u003cp\u003eOKM describes the Delta Ranger as passive: it emits no magnetic waves. Magnetic fields and metal around you affect the results, so OKM asks you to keep about 50 m (160 ft) from electric motors, speakers and phones, to remove keys and jewelry, and to clear visible metal from the scan field. Calibrate the compass after every restart, away from power lines and electric fences. The control unit pairs with the app over Bluetooth 5.2 with a range of about 8 m (25 ft) line of sight, and the Bluetooth headphones pair with the smartphone. Scans open on the phone, and you copy them by USB to the Windows notebook for Visualizer 3D Studio.\u003c\/p\u003e\n\n\u003cp\u003eThe laser pointer is Class 3R, so avoid direct eye exposure. Do not use the detector during thunderstorms, and if it finds ammunition, do not touch it: OKM says to report it to the police.

OKM reports that customers have found objects down to 8 m (26 ft) with this technology; we read that as a best case for large objects, and small items such as coins read far shallower.\u003c\/p\u003e\n\n\u003ch2\u003eWho the OKM Evolution NTX suits\u003c\/h2\u003e\n\u003cp\u003eWhat we like about the Evolution NTX is that it pairs conventional metal detection with 3D ground scanning in one control unit.

The Rover UC gives acoustic, haptic and visual feedback and basic target discrimination between ferrous metal, non-ferrous metal and cavities; in Pinpointer mode it shows ferromagnetic and non-ferromagnetic metal separately. Bluetooth headphones connect to the watch or to a smartphone.\u003c\/p\u003e\n\n\u003cp\u003eThe pole adjusts to your height for a comfortable posture, and OKM says the sensors respond more sensitively as the pole gets longer, which helps with smaller objects at greater depth. The watch also carries fitness tracking (step counter and heart rate), a compass and GPS that you can switch off. The battery charges over a USB-C cable. OKM reports that customers have found objects down to 20 m (65 ft) with this technology; we treat that as a best case for large objects, not a depth for coins.\u003c\/p\u003e\n\n\u003ch2\u003eWho the OKM Rover UC suits\u003c\/h2\u003e\n\u003cp\u003eWhat we like about the Rover UC is its unusual form factor.

It suits customers who put portability first within the OKM ground scanning lineup.\u003c\/p\u003e\n\n\u003ch2\u003ePortability and the smartwatch interface\u003c\/h2\u003e\n\u003cp\u003ePicture walking a large property where carrying bulky equipment would be a chore. The compact pole is easy to transport, and the smartwatch gives you a compact control and information screen. A smaller instrument does not automatically match every larger scanner, and the watch display is no substitute for detailed review of the scan data on the notebook.\u003c\/p\u003e\n\n\u003ch2\u003eScanning technique on the Rover UC\u003c\/h2\u003e\n\u003cp\u003eEven with a compact instrument, systematic measurement matters.

Changes in underground materials reflect the radar signal, and those reflections can point to possible structures or other anomalies. The Gepard does not identify what caused a reflection, and interpreting radargrams takes training.\u003c\/p\u003e\n\n\u003ch2\u003eSoil decides how deep the Gepard reads\u003c\/h2\u003e\n\u003cp\u003eGPR performance depends heavily on ground conductivity. Dry, relatively resistive ground generally allows better penetration. Wet clay and highly conductive soils can cut penetration sharply. OKM quotes depths of up to 40 m (131 ft); we treat that as a maximum, not a guaranteed detection depth. Usable depth depends on soil conditions, antenna setup, target size and the resolution you need.\u003c\/p\u003e\n\n\u003ch2\u003eOne mistake to avoid with the Gepard GPR\u003c\/h2\u003e\n\u003cp\u003eAssuming GPR produces photographs of underground objects.
