Prospector 100 Metal Detector [ HOT · Workflow ]

The detector transmits an electromagnetic field into the ground via a transmitter coil. When this field encounters a conductive metal object, it induces eddy currents in the object, generating a secondary electromagnetic field. A receiver coil detects this secondary field and alerts the user.

It is built with an adjustable S-rod and an lightweight frame (usually around 3–3.5 lbs), designed for comfort during long searching sessions. prospector 100 metal detector

| Phase | Duration | Deliverables | |-------|----------|---------------| | Alpha prototype | Month 1–3 | Breadboard circuit, 14 kHz coil, basic AM mode. | | Beta prototype | Month 4–6 | Full PCB, 28 kHz switching, enclosure, companion app v0.9. | | Field test | Month 7–8 | 20 units to experienced prospectors (Australia, USA, South Africa). | | FCC/CE certification | Month 9 | EMC, SAR, safety. | | Production tooling | Month 10–11 | Injection molds for coil & control box. | | Pilot run (500 units) | Month 12 | QA test, adjust assembly line. | | Full production | Month 13+ | 10k units/month capacity. | The detector transmits an electromagnetic field into the

While it cannot compete with mid-range detectors regarding depth in mineralized soil or target separation in "carpet of nails" scenarios, it provides a high return on investment for beginners. It is an ideal tool for casual coin shooting, beach combing (dry sand only), and introducing new users to the mechanics of metal detection without a steep learning curve. It is built with an adjustable S-rod and

It generally operates on a Very Low Frequency (VLF) principle, making it sensitive to smaller jewelry and coins.
