When it comes down to the best brands of metal detectors, Fisher is one of the big brands. Metal hunting enthusiasts hold the Fisher brand in high regard, and though there might be some division between the top fans of Fisher and Garret brands, each brand carries its sway with its crowd, and Garret also has its loyalists.

In this Fisher F75 review, we look at what has been regarded as one of the best models of metal detectors ever produced by the Fisher Brand, Fisher F75. The Fisher F75 represents the latest and also the greatest devices from the brand. The F75 features a design and features made possible by the use of the best and the latest technologies around gaining the greatest possible depth level, audio functions, and target separation. Thanks to these features, you access new passageways for new grounds, especially if they are full of iron.

Note that the vastness and the robustness of the features of this F75 mean that you’ll pay more for the detector than you would with other brands/ mode is.

Intended Users

Before we look at the features of this metal detector, it’s important to note that the detector is an excellent fit for beginners interested in exploring the world of coin shooting/ hunting, or even the hunt for gold, relics, and jewelry. Its versatility comes from its ease of operation, the accuracy in its notch discrimination, and its general effectiveness.


One of the most impressive features of this detector has to be its unmatched level of accuracy and discrimination, which makes this the best detector for coin or jewelry hunting on land that is infested with iron. You can sift through rubbish easily to find the items you desire.

Besides its accurate discrimination, this metal detector also boasts with an impressive feature, the DST Mode. DST is Digital Shielding Technology in full. It can be turned on and off easily.

What does DST do? DST, as its name suggests, is effective in the reduction of the electromagnetic interface, better known as the unwanted signals that could distort your results.

Features and Functions

Lightweight Design

In your search for the best metal detectors, it’s paramount to check if carrying and swinging the detector’s coil around will be an easy task or not. In this case, you need to check the weight of the detector. The F75 is very easy to carry around since it only weighs 1.6kgs. It is one of the lightest detectors on the market, and you can carry it all day long without feeling fatigued.

But its low weight isn’t the only reason for its ease of use and portability. F75 also boasts an ergonomic design, and it’s regarded as the top ergonomic metal detector on the market. It is well-balanced and easy/ comfortable to hold/ carry.

Speaking of comfort, you will be happy to note that this metal detector boasts a high level of weight distribution, not to mention its perfect width settings and the position of the armrests. The grip handle is extra comfortable thanks to the foam-covered grip. The controls are also very easy to use.

Therefore, this Fisher F75 could be the best metal hunting investment you make today. The process of putting the parts together is easy and quite straightforward.

Power Source

F75 runs on 4 AA batteries, just like all the other top-rated metal detectors. Its runtime is, however, the most impressive since it lasts as much as 40 hours. Although the runtime varies depending on the activated settings, this is a very impressive function.

If you are looking for more fluidity in the power options, buying the rechargeable batteries would be an excellent idea. Even though the rechargeable batteries mean a reduced runtime, they result in long-term savings.

Frequency of Operation

The Fisher F75 is a high-quality and very sensitive 13kHz VLF detector. If you have used other metal detectors by Fisher, this operational frequency is similar to F70’s, and it’s quite impressive. Note, however, that if you need a higher operational frequency, you might have to opt for the Garret AT Pro since it has a high operational frequency.

But the operational frequency of 13kHz is not that low since you can detect smaller objects than you would with an 8kHz frequency provided by other detectors. At 13kHz, the detector will detect more materials, without discriminating or sacrificing the depth too much. Therefore, if you are searching for a great metal detector for relics, coins, or jewelry, this is a good choice for you.

You shouldn’t, however, invest in this metal detector if you are looking for a device that is ideal for prospecting gold. Although it picks up gold jewelry, it doesn’t have enough sensitivity to detect gold flakes or gold nuggets.

Keep in mind that this metal detector is a single-frequency detector that comes with a function for shifting the frequency.

Search Modes

To enhance its search options, this Fisher F75 has three search modes, and to these are all-metal modes.

These search modes include:

Discrimination –

The discrimination mode is the ideal function to use if you need to pick out the right objects from nails, iron trash, foil, and pull tabs. This is the setting that bears the lowest level of sensitivity. This mode allows the adjustment of sensitivity, as well as the adjustment of the number of tones, the discrimination level, notch, and the process number.

Motion All-Metal –

this setting is the most sensitive of the three, and it offers more depth coverage compared to the discrimination mode. Note that the detection coil has to be in motion for the detection of the object.

Static All-Metal –

To examine large and deep-seated objects like coins that are or than 12inches deep, this setting does the job. Note that unlike the discrimination and the All-Metal Motion modes, the coil mustn’t move in this mode.

Note: If using either of the all-metal modes, you will have access to the sensitivity adjustable functions, as well as the functions for ground balance and audio pitch. It’s also worth noting that you can only adjust the manual ground balance function when the all-metal mode is turned on. However, the setting does carry over when you switch over to the discrimination mode.

The setting for the signal strength threshold falls under the motion mode. This setting is unavailable in the static mode.

Numerical Target ID

As one of the metal detectors that falls in the mid-range category, this F75 comes with a numerical targeting ID on a 0-99 scale. The target ID depends on the conductivity of the metal.

To enhance the specificity of the targets, also present is the Iron tone audio functions and the discrimination settings. All these functions work to enhance the accuracy of the readings.

Some of the target IDs you should be aware of include:

  • US Silver Eagle – 91
  • US Quarter – 80
  • Clad Dime – 70
  • Aluminum pull-tabs – 35-55
  • US Nickels – 30
  • Iron objects – 4-12

Besides the numerical IDs, there also are categories of the target ID on top of your display. The categories enhance the estimation of the targets, as well as their discrimination.


In the search for coins, relics, and jewelry, and as long as you use a metal detector, you must develop a keen understanding of the discrimination function around the detectors.

Take this F75; for example, its discrimination readings/ functions run from level 0 to 65, meaning that targets that exist below any selected value are unacceptable.

In this case, if you wish to eliminate iron from your results, you’d have to adjust your readings to 15. Doing this gives you a balance in junk elimination, and you don’t have to worry about removing any valuable targets. At the same time, a higher setting on the discrimination setting could mean the rejection of aluminum trash and zinc pennies, or jewelry and nickels.

The introduction of the notch discrimination function by Fisher allows you to either eliminate or to accept specific targets by using the scaling categories provided.

To keep zinc and nickel categories, you could remove the FOIL and the TAB categories.

Thanks to the dual use of the discrimination function with the notch functions, you can easily discriminate the objects you are not interested in.


For the accuracy of your guided searches, you might like F75’s large LCD screen that is very easy to use thanks to its numerical ID targeting, the menu button, and the dial-settings knob. Everything is on the face of the display screen, and you can adjust or pick the correct readings easily.

Its three-button control system makes this metal detector super easy to use. Even though changing the settings is not as easy or fast, the functions for control work well.

Fisher F75 also comes with a trigger switch located behind the control screen. When you pull the switchback, all the metal objects will be detected even without any motion. It also allows you to pinpoint different object locations. Also, when the button is pushed forward, you activate ground balancing.

The backlight is the other nice feature that enhances the ease of use of the detector. You can see the readings on the screen in bright and dim conditions.

Search Coils

Everything about the results you obtain from a metal detector depends on the design and the function of the search coils.

Fisher F75 features a standard 12inch elliptical DD search coil that is waterproof. Thanks to the design of the coil, you could use it in a stream or a shallow creek.

Even though most metal hunters opt for metal detectors with the concentric coils, the search coil in this F75 does a pretty good job as it separates the targets easily even as it ignores ground mineralization. The coils are the reason for the coil’s top performance.

Ground Balance – Ground or Automatic

If you have been looking for another convincing reason for you to choose this Fisher F75, then its adjustable ground balance function should be it. F75 allows you to use either the manual or the automatic adjustment options, increasing the accuracy of your finds. These options also mean that you can easily ignore the unnecessary ground minerals like iron and the dissolved salts.

The automatic function for ground balance does an impeccable job of calibrating your current ground conditions. But if you need to calibrate conditions during gold hunting or saltwater hunting, then the manual option works best. Note, however, that the manual function calls for a little practice.

In either case, the sensitivity of the detector means a high level of accuracy in your results.

Iron Audio Tones

This detector comes with a menu setting function that allows for easy adjustment of the tones. You have four tone options to choose from, and these tones will vary depending on the conductivity of the target metal object. Besides the four tones, there’s also the delta pitch, which varies with the target IDs. The delta pitch is ideal for use when hunting for relics in the high trash areas.


The detector allows for the adjustment of the device’s sensitivity in relation to the existing ground mineralization conditions. Note that the higher sensitivities give you a greater depth coverage, even though you must be aware of ground mineralization chatter.

Mineralization Graph

The other unique feature of this metal detector is its mineralization graph, which gives you accurate data regarding the mineralization factor of the soil.

The Trigger Pinpointing Mode

For the accurate location of targets, this pinpointing mode is essential.


Besides the waterproof design of the search coil, this detector also boasts weatherproof features. Note, however, that the control panel is not waterproof.
