This is a “turn on and go” detector and is best suited for entry-level detectorists looking for a powerful and affordable all-around machine for coin, jewelry, and relic hunting.
Before we dive into the specs of the F22, let’s take a high-level view of the pros and cons:
Now let’s dive deep into the features of the F22!

Fisher created a brand new coil design for the F22 – it is a 9” triangulated, elliptical concentric coil.
It’s a smaller, more narrow coil which is excellent for picking out good targets amongst iron and trash.
It’s also perfect for moving around in tight spaces like in between large rocks and at playgrounds.
The coil is also fully submersible so you can use in shallow water. Just remember not to get the control box wet as it’s only weatherproof – not submersible!
The F22 comes with four search modes so you can set your preferred discrimination pattern:
- Jewelry – discriminates all iron targets.
- Coin – discriminates all iron targets as well as pull tabs and other trash items.
- Artifact (relic) – does not discriminate and will include all iron signals.
- Custom – allows you to set a custom pattern using the notch feature.
LCD target ID screen
The large LCD screen on the F22 has many indicators such as:
1. Target Category ID Numbers which tells you the type of metal you’ve found (i.e., gold, silver, iron)
2. Two-Digit Number Target ID (1-99) which is an even better indicator of the type of metal found.
This number factors in the metal conductivity as well as the target size and positioning in the ground.
Here are a few of the more common number target ID readings for the F22.
- Iron objects 1-19
- U.S Zinc coins (dimes and quarters) 50-59
- U.S Copper Coins 60-69
- U.S Silver Coins 70-79
3. Iron Indicator helps you discriminate unwanted iron trash signals – ideal for coin and jewelry hunting!
4. Current Search Mode allows you to toggle between modes to change your discrimination pattern quickly.
5. Target Depth Indicator gives you an estimate of how deep the target is.
6. Battery Level Indicator so you never run out of batteries during a long hunt!
7. Menu Category Icons so you can quickly adjust your volume, sensitivity, and notch.
This detector has four tones – base, low, medium, and high.
Use these tones in conjunction with the numeric 1-99 ID to get a good idea of the target in the ground.
The chart below illustrates how the audio tones match up to the target ID categories in each of the three factory-set search modes.
The iron audio feature (or FeTone) is a technology not usually found in entry-level machines.
This feature allows you to amplify iron signals so you can save time by not digging unwanted targets.
If you’re looking to do coin and jewelry hunting, this feature is invaluable. It will save you countless hours of needless digging – not to mention back pain!
