Why Fisher Still Earns Its Place in the Field
Fisher Labs has built metal detectors since 1931 from its El Paso, Texas factory, making it the oldest continuously operating name in metal detection. Detectorists choose Fisher metal detectors because the lineup leans on clear audio and manual ground balance, with durable controls that hold up across desert prospecting and iron-heavy relic ground. The Gold Bug Pro and Gold Bug 2 remain the reference VLF prospecting machines in the western US. The F75 has held its place on competition relic hunts for more than a decade. Every current Fisher detector ships from a US factory and carries the full Fisher Labs manufacturer warranty.
Fisher Gold Bug Series: Built for Mineralized Ground
The Fisher Gold Bug series is the brand's signature gold prospecting line and the reason many prospectors associate the Fisher name with nugget hunting. The Gold Bug Pro runs a single 19 kHz frequency with two search modes (All Metal and Discrimination) and a 0 to 99 numeric target ID. Ground Grab sets automatic ground balance, and the +/- buttons fine-tune manually for positive or negative ground response. It weighs 2.5 lbs and runs about 15 hours on a single 9V battery. The Gold Bug 2 steps up to 71 kHz for sub-gram and pinhead-sized gold. It carries three auto-tune modes, dual-knob manual ground balance for fine tuning, an Iron Disc mode for hot rocks, and an audio-boost mode for faint targets. The Gold Bug 2 weighs 2.9 lbs and runs up to 35 hours on dual 9V batteries. Both ship with waterproof search coils, though the control housings stay above water.

Gold Bug Pro vs. Gold Bug 2: Which One for Your Ground?
The Gold Bug Pro is the versatile pick for prospectors who also hunt coins and shallow relics. The 19 kHz frequency reaches reasonable depth on US silver and copper while still finding small gold flakes in low to moderate mineralization. The Gold Bug 2 at 71 kHz sacrifices coin and relic versatility for extreme small-gold sensitivity in highly mineralized soil, with the dual-knob manual ground balance refined enough to chase pinhead nuggets in dry-stream beds. Most western US prospectors run the Gold Bug Pro as a do-it-all and reach for the Gold Bug 2 once they confirm a hot patch.
Fisher F-Series: Single-Frequency VLFs from F11 to F75
The F-Series covers entry-level through expert detecting on a shared 7.69 kHz VLF platform (the F75 runs higher at 13 kHz). The F11 is the simplest model in the line. It carries three preset search modes (Coin, Jewelry, Artifact) plus a 7-inch concentric waterproof coil. IP54 weatherproof construction covers it for park and yard coin shooting in rain and damp grass. The F22 adds a fourth Custom search mode and steps up to a 9-inch waterproof concentric coil, which suits beginners who hunt across variable conditions. The F44 widens the lineup with five search modes (Jewelry, Coin, Artifact, Custom, and All Metal) and a backlit display. The 11-inch triangulated concentric coil reaches deeper coins than the F22 in moderate soil. The F70 and F19 sit between the F44 and F75. Both carry DST EMI suppression and 11-inch DD coils, with multiple search modes and adjustable iron discrimination. Aftermarket search coils for Fisher detectors open up tuning options for trashy sites and open fields.
Fisher F75: The Expert's All-Terrain VLF
The F75 is Fisher's flagship VLF for competition relic and coin hunters. It runs at 13 kHz with DST (Digital Shielding Technology) suppressing EMI in trashy sites near power lines, rebar, and electric fences. Adjustable iron discrimination and multiple search modes give experienced hunters the control they need on Civil War relic sites and silver-rich colonial homesteads. The standard 11-inch BiAxial waterproof coil punches through moderate mineralization on deep silver. Four AA batteries run the F75 for about 40 hours, longer with lithium cells. The F75 is made in the USA, and the recovery speed and depth-to-weight ratio still benchmark well against detectors twice the price.
Fisher Specialty Detectors: Two-Box and Underwater Models
Fisher's specialty lineup covers use cases beyond standard coin and gold work. The Gemini-3 is a deep-seeking two-box detector with separate transmitter and receiver boxes, operating at 82 kHz with V.C.O. audio response. It runs inductive and conductive trace modes and locates large buried targets to a depth of 20 feet, plus buried utilities and mineral seams. The 1280X Aquanaut is the submersible underwater detector, rated to 250 feet at 2.4 kHz with up to 75 hours of battery life on 8 AA cells. The lower frequency rejects salt and wet sand response, which makes the 1280X the right tool for surf zone and shallow-water diving. The Impulse AQ uses pulse induction for saltwater beach and surf hunting where VLF detectors fight ground response. The CZ-21 is the legacy underwater VLF, handling dive depths similar to the 1280X with a different audio profile.
How to Choose the Right Fisher Detector for Your Hunt
Match the detector to the target and the ground rather than chasing feature lists. Gold prospectors working high-mineralization desert and dry-stream beds run the Gold Bug Pro for general use and reach for the Gold Bug 2 in sub-gram nugget patches. Coin shooters working parks and lawn permissions take the F22 or F44 depending on coil size and how much menu depth they want. Expert relic hunters working iron-heavy Civil War and Revolutionary sites reach for the F75 with the BiAxial coil. Beach and surf hunters move to the 1280X Aquanaut or the Impulse AQ once salt response makes a VLF chatter. Cache hunters scanning old homesteads and abandoned mining camps for safes and buried equipment need the Gemini-3 two-box rather than a precision coil detector. Most hunters end up owning two Fishers, a gold machine and a coin-relic machine, and the brand pricing structure keeps that two-machine setup within reach for most hobbyists.
