Key Features
- Precise Multi-Metal Detection: Accurately identifies the buried location of objects and distinguishes between metal types — including gold, silver, copper, and gemstones — using its built-in frequency adjuster (400–470 MHz).
- Exceptional Sensitivity & Stability: Designed for easy, user-friendly operation with outstanding detection consistency, even in challenging outdoor environments.
- Intelligent Modular Operation System: Powered by a microcomputer CPU-controlled chip with self-test and calibration functions, ensuring fast, efficient scanning with minimal setup time.
- Remote Search System: The handheld searcher communicates wirelessly with the host unit. When a target object is detected, the searcher sways left and right — with larger amplitudes indicating larger finds.
- LCD Display Screen: Clear 95 × 55 mm display screen for easy reading of detection settings and results in the field.
- Rechargeable Battery: Built-in AAA hydrogen rechargeable battery (1,000 mAh) — charges fully in 8–10 hours via included power plug. No disposable batteries needed.
- Durable Aluminum Body: Compact and robust construction measuring approx. 292 × 103 mm for easy portability during outdoor treasure hunts.
