GOLD VISION

The GeoGround Gold Vision is the brand's top gold and treasure instrument, and it works differently from a conventional coil detector. Instead of a VLF or pulse-induction search coil it uses a Smart Sensor probe, a Signal Booster Dish and a pair of RF antennas, all driven from a single hand-held electronic unit. GeoGround specifies six search systems: 3D Ground Scan, which sweeps the Smart Sensor over a marked grid to read changes in the magnetic field and sends the data over Bluetooth to the GeoGround 3D Analyzer app for Android, where it is drawn as a three-dimensional graphical map; Long Range, which works through the RF antennas with selectable soil type, target type and scan distance; Free Mode, for entering an exact search frequency; Smart Depth, which estimates the depth of a located target; and the Ionic and Bionic systems, which respond to ionic fields and let the operator sample a reference metal — a gold coin, for example — so the search leans toward that metal. GeoGround publishes no maximum depth and no maximum scan range for the Gold Vision, and any range figures quoted elsewhere are the manufacturer's or the dealer's claim rather than a published specification. The electronics sit behind a 3.5-inch colour TFT display — 480 × 320 pixels, 65,536 colours, LED backlit — running on a 72 MHz ARM processor with 2 GB of SD storage. Menus are available in eight languages: English, German, Spanish, French, Russian, Italian, Arabic and Persian. Power comes from a built-in, non-removable 9,600 mAh lithium-ion battery charged from a 100–220 V supply at 5 V / 2.5 A, and the unit adds a 3 W speaker with a 3.5 mm headphone socket, a vibration alert, an LED work light and a 650 nm laser pointer. The demountable wireless handle keeps the antennas independent of the display unit. The complete kit — main unit, Smart Sensor, Signal Booster Dish, wireless handle, RF antennas, charger, manual and warranty card — is supplied in a case measuring 400 × 300 × 160 mm at a stated 3,200 g. It is aimed at treasure hunters and prospecting teams who want a search-and-scan system in one case rather than a coil detector, and who work open ground where a scan grid can be laid out.
