The Fisher F75 Metal Detector is one of the newest and greatest models of its brand. It comes with innovative technology that makes this device more versatile in terms of detecting to a deeper depth, target discrimination, and audio features that have fashioned a new passageway for sites with iron.
Being the top-end metal detector in the Fisher brand, this unit is best in detecting relics, coins, and gold pieces with extreme convenience. In this review, we look at the Fisher F75 metal detector review to see what features it has that make it worth your money. Without much ado, let’s get into it.

Fisher F75 Metal Detector Review
Design and Appearance
The Fisher F75 is a relatively light metal detector that comes with high-end ergonomic features that the metal detecting industry can offer. When using this device, you can certainly feel comfortable holding and balancing it as you go about detecting.
Apart from its well-balanced weight distribution, the F75 comes with armrest position and width settings. The hand-grip is padded with foam for extra comfort. The controls are within reach for easy to use.
The F75 is powered by four AA batteries that you can depend on for up to 40 hours of metal detecting. However, this can vary depending on the settings you use during metal detecting exercise. It also accepts rechargeable batteries but with reduced run-time. But it is worth the long-term savings.
The Fisher F75 comes with a 13 kHz VLF operating frequency. This frequency is higher than that of the F5 and F4 but the same as the F70’s.
A higher operating frequency offers your greater small object sensitivity at the expense of depth. As such, the 13 kHz of the F75 will detect targets that lower frequency detectors like the F5 and F4 may miss minus compromise on too much depth. The high operating frequency makes the F75 a great metal detector for coins, relics and jewellery.
Although the F75 is a single frequency detector, it has a frequency shifting function that helps reduce chatter due to electrical interference.
The Fisher F75 comes with three search modes. These are:
- Motion All-Metal: This mode is the most sensitive and offers better depth even than the discrimination mode. However, the coil must be in motion for it to detect an item.
- Static All-Metal: This mode is designed for the larger and deep located objects – these objects can be larger than a coin and are located 12 inches deeper. The coil doesn’t have to move for the detection of the target to materialize.
- Discrimination: The discrimination mode is used when picking good targets out of trash such as pull-tabs, nail or foil. The discrimination mode is a motion mode that is not as sensitive as all-metal but very great for rejecting trash.
If you are using the all-metal modes, there are adjustable settings for sensitivity, ground balance, and audio pitch that you can utilize as well. The motion mode equally has settings for a signal threshold which is not available when under the static mode.
In discrimination mode, you can adjust sensitivity, discrimination level, number of tones, notch, and process number. Keep in mind that the manual ground balance setting can only be adjusted in all-metal mode. Nonetheless, the settings carry over if you switch to discrimination.
Automatic and Manual Ground Balance
The F75 comes with both manual and automatic ground balance. With both ground balances, this model can ignore most signals emanating from ground minerals such as dissolved salts and iron. The manual and automatic ground balance makes this model better suited for hot ground and rough terrain conditions compared to models with pre-set ground balance. With better ground balance, you will get less chatter and greater depth, especially when you get a proper ground balance.
The automatic ground balance will deliver you better performance since it can calibrate your current ground conditions. For instance, on saltwater or when gold hunting. Although manual settings can do the same performance, it requires practice to get it right.
The Fresher F75 offers you plenty of control over which target is rejected when you set to discrimination mode. The basic discrimination function provides a level from 0-65. Any target located below the value selected is not accepted.
If you want to eliminate iron, a setting of 15 will provide you with a balance between removing junk minus removing valuable targets. Higher settings can reject zinc pennies or aluminium trash. However, it may also lose nickels or jewelry.
The F75 also comes with a notch discrimination function which enables you to eliminate or include special targets using a scale of categories right at the top of your screen. For instance, you can remove “FOIL” categories while you keep the neighboring zinc and nickel categories. So, by combining the notch with discrimination function, you can let the F75 discriminate the objects you don’t want to detect.
Numerical Target ID
The F75 comes with a numeric target ID just like most metal detectors in the mid-range bracket. This F75 model has a 0-99 scale based on the metal’s conductivity. If you combine the numeric target ID with FeTone audio and discrimination settings, you can be sure to make an accurate guess about if you want to dig or ignore it. Here are some of the common numeric 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
This model also comes with a target confidence indicator with six segments. So, if the detector indicates a full six rating, be sure that the target ID is accurate. However, lower confidence ratings may show a junk target.
Control panel and Display
The Fisher F75 has a large digital screen that is easy to see the numeric target ID. The good thing about this screen is that the information displayed is clear and not so small. Therefore, you won’t have difficulty seeing it when in the field.
It features a three-button design, unlike the Garrett metal detectors that come with separate buttons for most of their settings. The control panel comes with a settings knob for adjusting the current settings while the menu button cycles through the various settings.
The screen provides enough contrast to be easily viewable. With the screen backlight, you can easily see the current settings in both dim and bright light conditions.
Other Features include:
- Digital Shielding Technology
- Trigger Pinpointing Mode
- Weatherproof design
- Mineralization graph
The Fresher F75 delivers excellent performance when it comes to metal detecting. It is certified to be the perfect choice for coin shooting, relics, or jewelry. One thing you will like about this model is the discrimination of unwanted targets. You can combine the notch, ID confidence, discrimination, and ground balancing to deliver you plenty of control while minimizing chatter from mineralization.
When it comes to depth, the F75 does an excellent job. When in all-metal mode, it can detect US coins up to 15 inches deep when in good conditions. If you want to take your hunt to the beach, this metal detector may handle the wet sand in lightly mineralized areas courtesy of the ground balance function.
To conclude the Fisher F75 Metal Detector Review. We can say it’s an excellent metal detector that offers great value for money. It is designed to perform well for relics, jewelry, and coin hunting. It comes with all the features we have reviewed above to ensure that its performance is top.
If you want an outstanding metal detector that performs great in different ground conditions, the Fisher F75 is what we recommend.
