The MD‑3006 Ground Metal Detector from Tianxun / Nanbei is a VLF‑based underground detector designed for both hobbyist treasure hunting and professional-relief tasks like relic detection or industrial inspections. Built with accurate orientation and strong discrimination ability, it can distinguish between ferrous and non-ferrous metals with good precision. It operates at a frequency of 15 kHz, which helps it maintain a good balance between depth penetration and sensitivity. Depending on the target and soil conditions, it can detect small objects (like a US 25‑cent coin) at shallow depths (~15 cm) and larger conductive targets (e.g. a 60×60 cm aluminum plate) up to ~1.4 meters deep.
The detector is powered by three 9V (6F22) batteries, offering flexibility in battery configuration. To help adapt to different ground conditions, it includes ground balance control, auto‑tune, and discrimination controls. Audio feedback is delivered via three distinct tone frequencies, helping you better identify target type. With a lightweight yet sturdy build (1.26 kg) and adjustable length, the MD‑3006 is a reliable choice for field detecting. Whether seeking coins, historical artifacts, or industrial metallic anomalies, this model offers a practical and cost-efficient solution.
