The Gemini III is designed to locate large, deep objects–like an iron chest, an ore vein or a metal pipe. With its two-box design, it offers much better depth penetration than a standard metal detector.
The Gemini-3 is used by professional treasure hunters, prospectors, geologists, and public utility employees. Depending on ground mineralization and target size, objects may be detected as deep as 20 feet. A pioneer in the field of metal detector over 60 years ago. Fisher has been advancing the state of the art ever since.
The Gemini-3 is Fisher’s best two-box ever. If you are a two-box treasure hunter, you probably already know the Fisher Gemini-3 has a reputation for being the best around.
