Handheld Detectors Overview
Before using your detector, read the Safety Warnings page. Always follow local laws and regulations regarding metal detecting in your area.
TreasureHunter3D offers a range of handheld metal detectors that pair with the TreasureHunter3D Visualizer smartphone app to deliver real-time scanning, 3D ground mapping, and audio detection — all in a compact, lightweight rod you carry with you.
Product Range
| Model | Key Feature |
|---|---|
| TreasureHunter | Entry-level handheld detector — 3D Basic scan mode |
| GoldenEye | Adds camera tagging and Position Indicator in 3D Advanced mode |
| GoldenEye Plus | Full Professional 3D mode with AR overlay and adjustable resolution |
| TreasureLight | Compact sensor probe with built-in illumination light |
The TreasureHunter3D Visualizer App
All handheld detectors are controlled through the TreasureHunter3D Visualizer app — free to download for iOS and Android.
The Professional 3D scan mode (GoldenEye Plus only) requires an iPhone 6S or later running iOS 11 or later.
What Can You Find?
The handheld detectors build a 3D map of buried objects — showing where to dig before you break ground. Typical targets include:
- Buried coins, rings, and jewelry
- Hidden caches and relics
- Underground metallic objects at depths of up to several metres (depending on size and soil)
The colour-coded scan grid shows red for highest-probability targets, yellow for probable, and green for clear ground — so you only dig where it counts.
