Fisher F75 Metal Detectors: The Best Detector on the Market

The Fisher F75 is one of the company’s most popular mid-range detectors. It is designed to find coins, relics, and jewelry in various environments.

This detector has several features, including a rapid response time, manual and automatic ground balance, notch discrimination, and digital shielding technology. It’s also designed to be lightweight and easy to use.

How does the F75 compare to other metal detectors? Is it worth the money? Let’s find out in this review.

Design, Appearance, and Ease of Use

The F75 is the lightest detector, but it is not the lightest one. It also has the best ergonomics, which means it is comfortable to hold and well-balanced.

The detector has a balanced weight distribution. You can choose the armrest position and width. The grip is comfortable, and the controls are easy to use.

These features are not very special, but they add up to a detector that is easy to use for a long time.

Putting the F75 together is easy – even if you’ve never used a detector before. Because you don’t need any tools, you may start looking nearly immediately after taking them out of the package.

Four AA batteries power the F75 detector. You can expect it to work for up to 40 hours, but this may vary depending on your settings.

The downside of the F75 is that headphones are not included unless you purchase a package deal. However, there is a standard ¼-inch jack, so you can use almost all headphones with a stereo plug.

Features and Settings

13kHz Operating Frequency

The F75 is a detector that operates on a frequency of 13kHz. This is the same frequency as the F70 but higher than the F5 and F4. It’s lower than the Garrett AT Pro, however, which has a frequency of 15kHz.

The F75 has a higher operating frequency, allowing it to detect smaller objects better. However, this comes at the expense of depth. The F75 can detect targets that a lower frequency detector may miss without sacrificing depth.

This makes it a great choice for relics, jewelry, and coins.

The F75 is not designed for finding gold. It can pick up gold necklaces or jewelry, but the frequency is too low to find small nuggets or flakes.

The F75 is a single frequency detector that can reduce chatter caused by electrical interference.

Numerical Target ID

The F75 detector is included in the mid-range bracket and has a numerical target ID.

The detector has a scale that goes from 0-to 99. This scale is based on how conductive the metal is. As you use the detector more, you will learn what different targets sound like. You can use this information along with FeTone audio and discrimination settings to help you decide if you should dig for a target or not.

Here are some typical target IDs for the F75:

  • Iron objects – 4-12
  • US nickels – Around 30
  • Aluminum pull-tab – 35-55
  • Clad dime – around 70
  • US quarter – around 80
  • US silver Eagle – Around 91

The F77 detector also includes a target confidence indicator. This is a scale with six segments. If the detector shows a full six rating, the target ID is accurate. Lower confidence ratings may mean that the target is not worth investigating.

There are two types of ID you can use on display. The first is numerical ID, which is used to quickly estimate the distance of an object. The second type is target ID, categorizing objects into different groups depending on how far away they are.

Search Modes

The Fisher F75 has three search modes. This includes two all-metal modes, an advantage the Fisher has over the AT Pro (Garrett only included a ZERO mode with their popular detector).

Here’s a quick overview of each mode:

  • Motion All-Metal – Object detection is better in this mode than in the discrimination mode. To detect an item, the coil must be moving.
  • Static All Metal – This model is better suited for detecting large or deep targets. Unlike the other two modes, the coil doesn’t need to be moving to detect a target.
  • Discrimination – Discrimination mode helps you find good targets from trash. This mode uses motion to help you find things like nails, pull-tabs, or foil. It is not as sensitive as all-metal mode, but it can help reject trash.

When using the all-metal mode, you can change a variety of parameters. These include sensitivity, audio pitch, and ground balance. There is also a motion mode with a setting for signal strength threshold. This is not available when in static mode.

There are different settings that you can adjust when looking for discrimination. These settings include the sensitivity, notch, discrimination level, number of tones, and process number. It’s important to know that only the manual ground balance setting can be changed in all-metal mode. If you switch to discrimination mode, it will stay the same.

Discrimination Settings

The F75 allows you to choose which targets are rejected when in discrimination mode.

The basic discrimination function provides a level from 0-to 65. This number is important to determine what targets will be accepted by the metal detector and what targets will not be accepted. For example, if you want to remove iron from your metal detector’s target list, you would set the discrimination level to 15. This would allow for removing junk targets such as aluminum cans and zinc pennies while still retaining valuable targets such as jewelry and nickels.

Fisher lets you choose which targets to include or exclude from the analysis with the notch discrimination function. You can do this by setting a scale of categories at the top of the screen.

You may, for example, eliminate the “TAB” and “FOIL” categories while retaining neighboring nickel and zinc categories. With a basic discrimination level, this would not be feasible.

The Fisher F75 metal detector is good for finding things you don’t want to dig up. It’s not as user-friendly as the Garrett AT Pro, but it gets the job done.

Manual or Automatic Ground Balance

The F75 detector can ignore signals from ground minerals like iron or dissolved salts, whether it’s done automatically or manually.

This makes the machine better suited to tough conditions and hot ground than machines with pre-set ground balance. When the machine has been properly ground balanced, you’ll get less chatter and greater depth.

The automatic ground balance function usually does a good job calibrating to the current ground conditions. However, manual ground balance can be used for saltwater or gold hunting, although it takes some practice to get it right.

This machine is not good for finding gold on tough ground. It is very sensitive, so it will pick up noise from wet saltwater sand. You can reduce the noise by adjusting the machine, but you will lose some depth in the process.

The range of adjustment settings on the metal detector helps it find good depth without creating a lot of false alarms.

Search Coils

The standard package includes an 11” elliptical DD search coil. This is waterproof, so it can be used in shallow creeks or streams. Most people would prefer a concentric coil, but the coil provided does a great job separating targets and ignoring ground mineralization.

The search coil is important for the F75’s great depth. It also makes it easy to pinpoint coins’ location, so you can be sure that the coin is below the center when you hear the audio tone.

Other Features

  • Sensitivity -The detector’s sensitivity can be adjusted depending on the ground conditions. If the ground is more mineralized, you will need to set the detector to a higher sensitivity to get a better depth reading. However, this also increases the chance of getting false readings from the minerals in the soil.
  • Tones – There is a setting for adjusting the number of tones. Depending on the target’s conductivity, you can choose one tone or four tones. There’s also a “delta pitch” setting depending on the target ID. This setting is useful for finding relics or when there is a lot of trash around.
  • Trigger Pinpointing Mode – The pinpointing mode helps you get an accurate target location before you start digging. It doesn’t require motion.
  • Mineralization Graph -The Fe3O4 graph is a useful feature. It shows the current mineralization factor of the soil.
  • Digital Shielding Technology – This function can be used to reduce electromagnetic interference. It’s useful near powerlines or other detectors.
  • Weatherproof design – The Fisher F75 has a waterproof coil, but the control box is not water-resistant.
  • Other Improvements – The Fisher F75 has continued to improve. The latest version has a faster response time for finding targets, which is great for areas with many targets. It also comes with an adjustable audio pitch when in discrimination mode and three new FeTone levels (Off, Low, Medium, or High).

Control Panel and Display

The F75 has a large digital screen that is easy to see. The important information is clear and not too small, so you won’t have trouble seeing it when you are in the field.

The Garrett F75 has a three-button design. A knob on the control panel adjusts the current setting while the menu button cycles through the numerous options.

The Garrett AT Gold is a simple system to use. It is slower to change settings than the Garrett AT Pro, but it is still easy.

There is also a trigger switch behind the screen. When you pull it back, all-metal objects are detected without motion. This can help you find where an object is located (assuming you’re not in static all-metal mode already). When you push the switch forward, automatic ground balancing is activated.

A bonus of this metal detector is the backlight. This makes it easier to see your current settings in low and bright light conditions. Most detectors in this price range don’t have this feature – including the Garrett AT Pro.


The Fisher F75 is an expensive metal detector. However, it often goes on sale for much less than the MRSP. It’s a matter of preference which computer you choose if you can find it for a similar price as the AT Pro.

Performance in the Field

The F75 is a great machine for finding coins, jewelry, and relics. It has a lot of features that make it perfect for the price.

Because it can discern between what you want to find and what you don’t want to find, the F75 is one of the best metal detectors. The notch, discrimination, ID confidence, and ground balancing help make sure that you find what you’re looking for while reducing the noise from mineralization. When the detector is in discriminate mode, you can also make it more sensitive.

The F75 metal detector is very good at detecting objects, especially in all-metal mode. Fisher metal detector estimates that it can detect US coins up to 15 inches deep in good conditions.

If you want to find treasure at the beach, the detector might be able to work in the wet sand near mineral deposits. It is a sensitive machine, so you will need to adjust the sensitivity to ensure it doesn’t falsely detect things. But it is surprisingly effective compared to many other detectors that work in these conditions.

Don’t try using the surf mode because it can’t handle these conditions. The control box isn’t waterproof either, so it’s not a good idea.

The AT Pro detector is stable on most types of soil. It also has a quick response time, which means it can separate objects well – even if there is a lot of iron trash.

Remember to keep your swing relaxed and wide when using the detector. The detector can provide a more accurate target ID with a higher confidence rating with a proper swing.

Comparisons with Other Detectors

Fisher F75 Vs. Garrett AT Pro

The Garrett AT Pro is a good metal detector. It is similar in price and performance to the F75. However, a few differences between the two can help you choose which one is right for you.

One of the biggest differences between the Fisher F75 and the AT Pro is that the Fisher F75 is not fully submersible. The AT Pro can be used to hunt underwater in an ankle-high or more water.

Fisher F75 Vs. XP DEUS

The XP DEUS is more expensive than the F75’s MRSP, but it is more expensive than the Fisher’s reduced current price. Is it worth the extra money, though?

The XP DEUS is the best detector for serious detectorists. It is a brilliant machine with multi-frequency technology, rapid response, and a fully wireless design. The DEUS can also handle almost any conditions, including wet sand and gold prospecting (with the GOLD FIELD mode).

Even though the XP DEUS is a good metal detector, the F75 is also a good metal detector for a much lower price.
