Product Description

Fisher Gemini-3 is built around this core: Two-box 81.92 kHz locator for large buried objects. Inductive Mode: Finds metal bodies by passing a signal through the ground. Conductive Mode: Uses optional ground rods to trace buried conductors such as pipes.

Narrow and Wide Scan: Switch between a tight search and a broad sweep. V.C.O. Audio: The pitch changes with the target response, with an analog meter beside it. A two-box locator is used to survey open ground for large buried objects, so it suits wide desert and farm plots in the UAE where you can walk a line slowly; tell us the target and the ground and we will say if it fits.

We supply the Gemini-3 as a genuine Fisher product. Fisher's own pages state a 2-year warranty on its detectors, and we will confirm what is in the box for the unit in stock. Always follow UAE rules and local permissions where you search. Message us on WhatsApp for the current price, availability and delivery.
