{"product_id":"fisher-gemini-3-two-box-metal-detector","title":"Fisher Gemini-3 Two-Box Deep Seeking Metal Detector","description":"\u003ch2\u003eFisher Gemini-3: When the Target Is Big, Deep, and Worth a Grid Search\u003c\/h2\u003e\n\u003cp\u003eEvery detectorist eventually meets a story a coil machine cannot answer: the strongbox buried behind the barn, the ore vein the old-timers worked, the iron pipe nobody mapped. Large targets at serious depth are a different physics problem, and the Gemini-3 is Fisher's purpose-built answer: a two-box detector whose separated 82 kHz transmitter and receiver ignore coin-sized clutter and reach for the big signal.\u003c\/p\u003e\n\u003ch2\u003eWhy the Gemini-3, and who it is NOT for\u003c\/h2\u003e\n\u003cp\u003eLet us do what other dealer pages will not and start with the disqualifier: the Gemini-3 does not find coins, buttons, or gold nuggets. It is deliberately blind to small targets; that blindness is the feature that lets it hunt deep without drowning in surface trash. If you want one machine for everything, look at our crossover detectors instead.\u003c\/p\u003e\n\u003cp\u003eFor its actual mission, it is the most accessible serious two-box on the market. Professionals use this class of machine for utility location and mineral exploration; treasure hunters use it for caches, hoards, and site features. You hunt it like a survey: walk your grid in a wide inductive scan to find the anomaly, tighten to narrow scan to shrink it, then let the V.C.O. audio pitch walk you to center. Conductive trace mode even follows metal pipes and cables you can attach to. Four modes, battery meters, and 60-cycle noise reduction for working near power lines: field-crew engineering, not gadgetry.\u003c\/p\u003e\n\u003cp\u003eWe also stock the XP Xtrem Hunter, the modern high-end two-box. The honest comparison: the Xtrem Hunter brings Deus II electronics at nearly three times the price; the Gemini-3 has done this exact job since before most detectors on the market existed, at $908. For a first cache machine or a utility crew tool, this is the sane entry.\u003c\/p\u003e\n\u003ch3\u003eSpecifications ([A] Fisher factory figures)\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpec\u003c\/th\u003e\n\u003cth\u003eFisher Gemini-3\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eTwo-box (split box) deep seeking\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrequency\u003c\/td\u003e\n\u003ctd\u003eCrystal-controlled 82 kHz TX and RX\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSearch modes\u003c\/td\u003e\n\u003ctd\u003eNarrow Scan Inductive, Wide Scan Inductive, Inductive Trace, Conductive Trace\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAudio\u003c\/td\u003e\n\u003ctd\u003eV.C.O. pitch response for pinpointing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNoise handling\u003c\/td\u003e\n\u003ctd\u003e60-cycle noise reduction circuitry\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower\u003c\/td\u003e\n\u003ctd\u003e16 AA batteries (8 TX + 8 RX)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBattery life\u003c\/td\u003e\n\u003ctd\u003eTransmitter 25 hr; Receiver 30 hr\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e7.5 lb (3.4 kg) complete; TX 2.5 lb (1.1 kg); RX 3.0 lb (1.4 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e20 x 12 x 7 in (51 x 30 x 18 cm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e5 years, Fisher Research Labs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBuilt\u003c\/td\u003e\n\u003ctd\u003eMade in the USA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eWhat's included\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eGemini-3 transmitter and receiver units\u003c\/li\u003e\n\u003cli\u003eHandle assembly for one-person two-box operation\u003c\/li\u003e\n\u003cli\u003eFisher 5 year factory warranty (First Texas Products)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eHistory Seekers is an authorized Fisher dealer. Two-box hunting is a niche, and we would rather talk you out of the wrong machine than sell it to you: call (256) 284-2247, tell us about the target and the site, and we will tell you honestly whether the Gemini-3, the Xtrem Hunter, or neither is the right call. The story is more important than the artifact.\u003c\/p\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3\u003eWhat is a two-box metal detector?\u003c\/h3\u003e\n\u003cp\u003eA detector with a separated transmitter and receiver carried on one handle (or by two people). The geometry makes it sensitive to large, deep, conductive masses while ignoring coin-sized targets, which is why it is the tool for caches, ore veins, and pipes.\u003c\/p\u003e\n\u003ch3\u003eHow deep can the Fisher Gemini-3 detect?\u003c\/h3\u003e\n\u003cp\u003eDepth depends heavily on target size and ground conditions; a large metal mass is detectable far beyond any coil machine's range. Fisher does not publish a single depth figure, and neither will we. Call us with your target scenario and we will give you a realistic expectation.\u003c\/p\u003e\n\u003ch3\u003eWill the Gemini-3 find coins or gold nuggets?\u003c\/h3\u003e\n\u003cp\u003eNo. It is intentionally designed for large targets only. For nuggets see our Gold Nugget Detectors; for coins and relics see our crossover machines.\u003c\/p\u003e\n\u003ch3\u003eCan one person operate it?\u003c\/h3\u003e\n\u003cp\u003eYes. The included handle assembly joins the transmitter and receiver into a one-person rig at 7.5 lb (3.4 kg); the boxes can also be separated for two-operator trace work.\u003c\/p\u003e\n\u003ch3\u003eWhat do utility crews use it for?\u003c\/h3\u003e\n\u003cp\u003eInductive and conductive trace modes follow buried pipes and cables; the conductive mode attaches directly to accessible metal lines. It is a working locator, not just a treasure tool.\u003c\/p\u003e\n\u003ch3\u003eGemini-3 or XP Xtrem Hunter?\u003c\/h3\u003e\n\u003cp\u003eThe Xtrem Hunter pairs two-box geometry with Deus II electronics and costs nearly three times as much. The Gemini-3 is the proven, affordable entry to the class. If you expect to hunt caches regularly and want target processing, step up; for occasional deep work, the Gemini-3 is the value.\u003c\/p\u003e","brand":"Fisher","offers":[{"title":"Default Title","offer_id":48106199548162,"sku":"GEMINI3","price":908.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0642\/9012\/8130\/files\/fisher-gemini-3-two-box-metal-detector.jpg?v=1783727897","url":"https:\/\/historyseekers.net\/products\/fisher-gemini-3-two-box-metal-detector","provider":"History Seekers Metal Detectors","version":"1.0","type":"link"}
