Fisher F22 Review: Popular & Highly Rated Metal Detector


If you remember the old Fisher F2 metal detector, which was the number one model for many years, you’ll be happy to know about its improved version, the Fisher F22.

This is an entry-level model costing about $100, but with all the serious features you’d expect.

The F22 is a great solution in a small, lightweight package, with a lower price, a new search coil design, and updated detection modes.

Who is the Fischer F22 right for?

The F22 is an entry-level steel detector, ideal for beginners and inexperienced users. It is very easy to set up and familiarize yourself with the detection types, making it simple to use. Many options can also be easily explained by the sound and data displayed on the LCD screen.

It’s a steel detector for beginners, but with upgrades, even beginners can hone their detecting skills and move on to more advanced machines when they’re ready to take it to the next level.

How does the Fischer F22 do it?

The Fischer Steel detector uses VLF technology, which produces a continuous wave of a single frequency. Operating at 7.69 kHz, it is in the right place in the gold zone in terms of depth and sensitivity. A number of factors determine the success of its detection depth, and whether it can penetrate the bottom and acquire good targets.

It should be able to detect coin-sized targets to a distance of 10 cm. Larger targets have been detected at depths of 12 inches or more.

The F22’s effectiveness is further enhanced by its underwater capabilities. You can go to marinas, lakes, and various freshwater locations to search for treasure.

Options and Benefits

Target Identification Options

Perhaps the most useful option for customers is the Target ID display. Estimated measurements and depth values can be displayed on the screen, but the steel target type is usually interpreted using voice or human signals. Fischer steel detectors are available with two types of target ID displays: classes, which are classified by numbers, and two-digit numbers.

Target class IDs are indicated numerically with “FE” standing for iron: a class numbered 2 through 5 means the target is probably gold, and a class numbered 6 through 9 means the target is probably silver. Gold bars are at the bottom of the FE scale, with small bars at levels 2 and 3 and large bars at levels 4 and 5. These numbers are used to identify the type of coin. Silver target ID numbers refer to U.S. silver, for example, dime 6, quarter 7, half dollar 8, and greenback 9.

Target ID also measures the electrical conductivity of the target, with low numbers referring to objects such as steel, aluminum foil, coatings, and nickel. Medium numbers refer to objects such as pull tabs, jewelry, and zinc covers. Increasing numbers indicate the presence of copper, silver, and relics. There is also an estimated depth indicator to give you an idea of how deep the treasure is buried.

Iron Audio.

FeTone is an identifier for the iron-based sound signature in Fischer steel detectors. Note that it may not be visible on entry-level equipment. The principle of operation is that the number of iron targets can be adjusted: if set to 10-20, the iron sound will oscillate from quiet to maximum, while non-iron targets will always oscillate at the maximum number set to 10-20. If it is set to 1-10, iron targets will be non-iron targets. The targets can be as noisy as the targets.

They work well on dry sand and beach towel racks but are not suitable for use in saltwater. This is also a drawback of all VLF detectors.

Extremely Light

The Fischer F22 is extremely lightweight, weighing only 2.3 pounds. It is foldable, measuring 22 x 8 x 5 inches, but the handle can be adjusted in size. The lightweight and compact design make it suitable for treasure hunters of all ages, starting at 10 years old.


Make no mistake, the search coil and shaft are water-resistant, so you can scout in shallow water. The control area and cable connection area of the search coil are not waterproof. This means that the Fischer F22 can be used in harsh environments, but waterproofing is not required.

Newly Designed Search Coil

The 9″ search coil supplied with this steel detector was designed specifically for the F22. It is a triangular, elliptical, concentric and waterproof coil. It is the perfect size for detecting small objects and the right shape for confined spaces.

Precise Positioning

The Fischer F22 has a locating function. When activated by pressing the specified button in the PP, you can determine the exact position of the target. You’ll know you’re heading in the right direction when the maximum sound is heard and the depth indicator shows the smallest step in relief.

Depth Indicator

One illuminated step may mean that the room is less than 10 cm from the ground, two steps mean that it is buried at a depth of 10 to 15 cm, and three steps mean that it is buried at a depth of 15 cm. It can be noted that this is not the case. However, three segments mean that the target is very large and very deeply buried.

Buttons And Patterns On The Fischer F22

The buttons on the Fischer F22 are fairly minimalist. There are only buttons to help you select energy, menu, point, mode, and settings.

The menu gives you access to sensitivity, notch, and quantity settings. The mode allows you to scroll and select the desired mode.

This steel detector has four preset modes. They are

  • Jewel Mode. This mode allows you to ignore objects that are primarily made of steel.
  • Parts mode. Besides iron, this mode also rejects objects made of aluminum or aluminum foil.
  • Artifact mode: The steel detector does not reject anything, but instead activates all target categories of this model.
  • Custom Mode: This mode allows you to select the tone you want. You can assign any tone depending on the material you wish to examine.

The target category is displayed at a higher position on the program display screen. They are divided into EFs and numbers from 2 to 9, and are highlighted or “disappeared” depending on whether you have selected the fabric or its nickname. Each grade represents a different metal.

The sensitivity of the Fischer F22 can be set from 1 to 10.

The F22’s precision aiming feature gives you a better idea of the target’s position and scale. The best and loudest sound will be displayed in the middle of the article. This makes the conclusion even more true.
