UIG Gold Digger

The UIG Gold Digger is the conventional, coil-based machine in GER Detect's UIG line: a true VLF induction-balance detector that sweeps a 35 × 25 cm waterproof Double-D coil over the ground and reads the return signal in real time. GER Detect specifies a selectable operating frequency of 5–45 kHz, which is the range that matters in gold work — lower settings for larger, deeper masses, higher settings for the small, low-conductivity targets that raw gold and thin jewellery produce. Seven search programs are supplied: General Search, Small Target, High Depth, Hard Soil, Smart Scan, Target Localisation (pinpoint) and a Custom program that stores the frequency signatures of more than twenty metals, so you can accept or ignore each one individually. Discrimination between precious and non-precious metals is automatic. Everything is driven from a 4.3-inch full-colour capacitive touchscreen (480 × 272 px) running on 72 MHz processing, with audio through a built-in speaker (350–5,500 Hz) or headphones. The external 11.1 V / 27 Wh lithium-ion pack is rated by the manufacturer at around 10 hours per charge. The detector with coil weighs 1,700 g and the shaft extends from 955 mm to 1,345 mm, which keeps long sweeping sessions comfortable; the complete kit in its case weighs 5,250 g. One detail from GER Detect's own specification sheet matters in the field: the search coil is sealed to 100 cm, but the control unit is weatherproof only and must never be submerged. The interface runs in six languages — Arabic, English, German, French, Spanish and Portuguese — and the unit carries CE and ISO 9001:2015 certification with a two-year manufacturer warranty. As with any VLF machine, realistic depth depends on target size, coil size and soil mineralisation: expect roughly 30 cm on a coin-sized object and around 1.3 m on a large buried mass in low-mineralisation ground, with the optional 18-inch AP coil trading small-target sensitivity for extra reach.
