Best Fisher Metal Detectors: Complete 2026 Buying Guide

Fisher Research Labs built its first portable metal detector in 1931, which makes it the oldest name in the hobby. Nearly a century on, the brand still does one thing and does it well: simple, rugged single-frequency VLF detectors that switch on and find things, backed by U.S.-based support out of El Paso, Texas.

That focus is the whole Fisher proposition. The F-series covers coins, jewelry and relics in the under-$250 and $250 to $500 bands. The Gold Bug series is a family of dedicated gold machines, from 19 kHz all-rounders up to the 71 kHz Gold Bug 2. And for the water there are three very different tools: the Impulse-AQ pulse induction machine for salt beaches, and the CZ-21 and 1280X, both submersible to 250 ft for divers.

This guide sorts the lineup out. Below: our top Fisher picks by use case, the complete lineup with 2026-verified specs, the four Gold Bug models explained side by side, and the head-to-head questions our phone line actually gets.

Quick Verdict: Best Fisher Metal Detectors of 2026

How We Tested and Ranked These Fisher Detectors

Every detector below was bench-tested with calibrated targets (clad and silver coins, gold jewelry, lead, and small nuggets at measured depths), then taken into real ground: mineralized Michigan clay, iron-heavy farm fields, wet and dry salt sand, and hot desert washes. We scored each on depth, target separation, target ID accuracy, ease of use and value, then weighted those scores by what the machine is built to do. A 71 kHz gold machine is not marked down for being poor on coins, and a pulse induction beach machine is not marked down for lacking a numeric target ID.

We also pulled the last 18 months of Fisher support calls and warranty returns. Fisher detectors are simple machines and it shows in the data: most calls are about settings, not failures.

Why Choose a Fisher Metal Detector?

Dr. Gerhard Fisher patented one of the first portable metal detectors and founded Fisher Research Labs in 1931. Today Fisher is part of First Texas Products in El Paso, Texas, alongside U.S.-based service and parts. The lineup has stayed deliberately simple while other brands have gone multi-frequency and wireless.

Five reasons detectorists choose Fisher:

• Menus you learn in an afternoon: most Fisher detectors have a handful of buttons and a clear numeric target ID. There is very little to get wrong.
• Dedicated gold machines at VLF prices: four Gold Bug models starting in the $250 to $500 band, including the 71 kHz Gold Bug 2 for the smallest nuggets.
• Real underwater options: the CZ-21 and 1280X are both submersible to 250 ft, and the Impulse-AQ brings pulse induction to the salt beach.
• Light and cheap to run: the F22 and F44 weigh 2.3 lb or less and run 25 to 30 hours on two AA batteries.
• 2-year manufacturer warranty: every current Fisher detector carries 2 years through an authorized U.S. dealer, with parts and service from First Texas in El Paso.

Best Fisher Metal Detector by Use Case

The F75 is the detector that built Fisher's modern reputation, and it is still the one we hand to someone who hunts old homesites and plowed fields. At 13 kHz it sits in the sweet spot for coins, buttons and relics, and the double-filter discrimination modes are what let it pull a good target out from between two nails. The numeric ID is steady, the menus are short, and FASTGRAB ground balance is a trigger pull.

Editor's pick: Fisher F75 LTD. The LTD adds Boost and Cache Locating modes for extra depth and large deep targets, and Fisher ships it with both the 11 in and the 5 in coil. The small coil is the one you want for tight, trashy ground.

Other ways to buy it: the F75 bundle with headphones, charger and rechargeable batteries and the F75+ with an F-Pulse pinpointer and digger. The standard F75 with the 11 in DD coil costs less.

The Gold Bug Pro is the Fisher most prospectors should start with. At 19 kHz it is sensitive enough for small nuggets, but it is also a capable coin and relic machine, which matters when you are learning and not every hunt is on a claim. Ground Grab balances to the soil with one button, and the manual control and live ground phase readout let you fine-tune when you cross from granite into red clay.

Editor's pick: Gold Bug Pro search coil combo. You get the 5 in DD coil for tight bedrock cracks and a 10 in elliptical for covering wash gravel. Bought separately the second coil would cost more than the difference.

The other 19 kHz Gold Bugs: the Gold Bug is the simplified version with the 5 in coil, and the Gold Bug DP pairs the platform with an 11 in elliptical coil for more depth. For the smallest gold, see the Gold Bug 2 below.

Best Fisher for the Smallest Gold: Gold Bug 2

The Gold Bug 2 runs at 71 kHz, far above the Gold Bug Pro's 19 kHz, and that frequency is what makes tiny, sub-grain nuggets ring out in ground that hides them from lower-frequency machines. It has a dual-knob manual ground balance, an iron disc mode for ferrous trash, and up to 35 hours on two 9V batteries.

It is a specialist. Coin target ID is not what it is for, and the manual ground balance takes practice. It suits prospectors who already know their ground and want a dedicated small-gold machine. The Gold Bug 2 with the 10 in coil and the two-coil combo are both in the $500 to $1,000 band.

The F44 is the step up most F22 owners make, and the Fisher we recommend when someone wants a detector they will not outgrow in a season. It keeps the simple layout but adds the controls that matter once you are hunting real sites: manual ground balance for mineralized fill, a Custom mode that remembers your settings, and a depth readout in pinpoint.

Editor's pick: F44 with the 11 in concentric coil. The concentric coil gives strong depth and clean target ID in mild to moderate ground. If you mostly hunt very trashy or highly mineralized sites, the F44 with the 11 in DD coil handles that ground better. Same detector, different coil.

The cheaper option: the F22 keeps the weatherproof body and four modes but drops the depth readout and manual ground balance. For a first detector it is excellent; for a little more the F44 is the one you keep.

Salt water conducts electricity, and on the wet sand a single-frequency VLF hears the beach as loudly as the ring. Pulse induction does not. The Impulse-AQ is Fisher's PI beach machine: it runs smoothly on wet salt sand and black sand, goes deep on gold and platinum rings, and adds iron and ground reject controls that let you skip some of the trash PI usually makes you dig.

What "Limited" means: this is the version Fisher rates waterproof to 1 m (3 ft) for up to four hours, with a 12.5 in mono coil and a detachable NiMH battery. It is for the surf line and wading to your waist, not for diving. If you want to go under, the CZ-21 below is the Fisher for that.

Worth planning for: battery life is short, about 3 to 3.5 hours, so most owners carry the 49 Wh lithium-ion battery pack. The 8 in coil with tube is the option for tighter spots, and Fisher's waterproof headphones are made for it. See our Fisher parts and accessories list.

The CZ-21 is Fisher's diving detector, and it has been a fixture on reefs and swimming beaches for years. It runs two frequencies, 5 and 15 kHz, which gives it the salt-water stability you need underwater while keeping a real target ID, so you can pass on a pull tab without surfacing to dig it. It is submersible to 250 ft.

Editor's pick: CZ-21 with the 10 in concentric coil. The larger coil covers more sea floor per pass. The 8 in version is the choice for rocky bottoms and tight spots. The coil is fixed, so pick the size you will use most.

The budget underwater option: the Fisher 1280X is also submersible to 250 ft, runs at 2.4 kHz, and gets up to 80 hours on AA batteries. It is simpler and has no dual-frequency salt handling, but it is a third of the price.

Every Fisher Pick Side by Side

For a wider view across every brand we carry, see our Best Metal Detectors of 2026 guide.

Best Fisher Metal Detector by Budget Tier

Under $250: Fisher F22 or F11

The F22 is the pick: four modes, a numeric target ID, a weatherproof housing and a 9 in waterproof coil at just over 2 lb. The F11 is the simplest Fisher, a good first detector for a casual hunter or an older child.

$250 to $500: F44, the Gold Bug family, F75 LTD and 1280X

This is the heart of the Fisher range. The F44 is the best all-around value. Gold hunters choose between the Gold Bug, Gold Bug DP and the Gold Bug Pro combo. The F75 LTD is the most capable coin and relic Fisher, and the 1280X is the cheapest way to take a Fisher under water.

$500 to $1,000: Gold Bug 2 and the F75 bundles

The Gold Bug 2 (with one coil or two) is the small-gold specialist. The F75 bundles add headphones, rechargeable batteries or an F-Pulse pinpointer to the flagship.

$1,000 and up: CZ-21 and Impulse-AQ

Both of Fisher's premium machines are water specialists. The CZ-21 is for diving. The Impulse-AQ Limited is for wet salt sand and the surf line. Pick by whether you are going under or staying on your feet.

The Comparisons Fisher Buyers Actually Ask About

The Gold Bug models explained (the most-asked Fisher question)

Fisher sells four detectors with Gold Bug in the name and the differences are not obvious from the box. Three share the same 19 kHz platform; the Gold Bug 2 is a different machine at 71 kHz.

Short answer: the Gold Bug Pro is right for most people, and the two-coil combo is the way to buy it. The Gold Bug 2 is the second detector for a prospector who already knows the ground and is chasing the tiny pieces. Gold Bug Pro | Gold Bug 2 | All Gold Bug models

Fisher Impulse-AQ vs. CZ-21: which one for the water?

Both are Fisher's answer to salt water, but they are built for different depths. The Impulse-AQ Limited is a pulse induction beach machine for wet sand and wading. The CZ-21 is a dual-frequency VLF you can take 250 ft down.

Short answer: if your feet stay on the bottom, the Impulse-AQ gets deeper on the wet sand and ignores the salt. If you snorkel or dive, the CZ-21 is the only one of the two that goes under, and its target ID saves you from digging every signal on the sea floor.

Fisher F22 vs. F44 vs. F75

The F-series climbs in control rather than in platform complexity. All three are single-frequency VLF, all have waterproof coils, and all carry a 2-year warranty.

Short answer: F22 for a first detector on a budget. F44 if you want room to grow and will hunt mineralized or iron-heavy ground. F75 if relic sites and trashy old homesites are where you spend your weekends. F22 | F44 | F75

How to Choose the Right Fisher Metal Detector

Step 1: Define Your Primary Use

• Coins & jewelry in parks and yards: F22 or F44
• Relics and iron-heavy old sites: F75 (or the F44 with the DD coil)
• Gold prospecting: Gold Bug Pro for most people, Gold Bug 2 for the smallest gold
• Wet salt sand and the surf line: Impulse-AQ Limited
• Diving: CZ-21, or the 1280X on a budget
• Deep caches and large objects: Gemini 3 two-box

Step 2: Match Your Experience Level

• Beginner: F11, F22, Gold Bug
• Intermediate: F44, Gold Bug Pro, 1280X
• Advanced: F75, Gold Bug 2, Impulse-AQ, CZ-21

Step 3: Decide How Wet You Are Going to Get

This splits the Fisher range quickly. The F-series and Gold Bug detectors all have waterproof coils, but the control housings are weatherproof at best, so rain and damp grass are fine and wading is not. The Impulse-AQ Limited is rated to 3 ft for up to four hours, which covers the surf line and wading. Only the CZ-21 and 1280X are built to go fully under, both to 250 ft.

Key Fisher Technology Definitions

VLF (Very Low Frequency)

The single-frequency technology behind every Fisher except the Impulse-AQ. Lower frequencies (the F22 and F44 at 7.69 kHz, the 1280X at 2.4 kHz) favor high-conductive targets like silver. Higher frequencies (the Gold Bug Pro at 19 kHz, the Gold Bug 2 at 71 kHz) are more sensitive to small, low-conductive targets like gold.

Pulse Induction (PI)

The technology in the Impulse-AQ and the F-Pulse pinpointer. PI sends pulses into the ground and listens for the decay, which lets it ignore salt water and most ground mineralization. The trade-off is weaker discrimination, so you dig more iron.

Ground Grab and FASTGRAB

Fisher's automatic ground balance. Pump the coil over clean ground and press the button (or pull the trigger on the F75) and the detector balances itself to the soil. Most models also allow manual adjustment for fine-tuning.

Double-Filter Discrimination

The F75's discrimination processing for trashy sites. It helps the detector recover quickly between targets, so a good target next to a nail is less likely to be masked.

Fe-Tone

Adjustable iron audio on the F22 and F44. Ferrous targets play at a lower volume instead of being silenced, so you still know the iron is there without it drowning out everything else.

V-Break

The Gold Bug Pro's variable breakpoint tone system. You choose the target ID where the tone changes, so iron can sound low while brass, lead and gold sound high.

Dual Frequency (CZ-21)

The CZ-21 transmits at 5 and 15 kHz. Combining the two is what keeps its target ID usable in salt water.
