Our Verdict: The Fisher F75 has the right balance of high-tech features that allows users to truly customize settings for the best performance regardless of the terrain. For the price, it’s a tool that every detectorist should own.

Who is the Fisher F75 Best Suited to?

The Fisher F75 is a metal detector that can be used by all. It does have high tech features and customizable settings that more experienced hobbyists will gladly take advantage of. This metal detector is a good example of how solid performance wipes out its higher-priced competition.

As for beginners, it might be harder to learn the machine, but it provides room to grow with features that will never be outdated. It’s expensive for a first-time buy, but a beginner amateur will find that it will last them a long time before ever needing to upgrade.

How Does the Fisher F75 Perform?

The Fisher F75 is a VLF 13kHz frequency and solid-performing metal detector that is a favorite of many serious relic and coin hobbyists. The standard F75 features the newest DST, FeTone, and FA technologies that makes it an ideal tool for relic and treasure hunting.

It has both automatic and manual ground balancing with a trigger-actuated function. The trigger is also used for easy and accurate pinpointing.

The F75 also features motion and static all-metal modes, adjustable threshold, and memory settings that allows you to turn your detector on and get busy right away. These settings will be well-used by the experienced detectorist to get maximum results regardless of the terrain. With the 11” searchcoil and covers for both the control box and battery compartment, you can tread water for some of the most elusive targets.

Features & Benefits

DST (Digital Shielding Technology)

DST is a feature that allows high-performance detection in high EMI terrains. It’s a shielding technology that suppresses this type of interferences so you can search those hard-to-work fields.

How does it work? The metal detector “works into the noise” by allowing as much depth detection and the use of high sensitivity settings with minimum background noise so that performance isn’t compromised.

Frequency shift is also available from F1 to F4 to help minimize or eliminate that chatter. However, if you are worried about performance at the cost of using DST, it can be switched “off” at your discretion.

FA Search Mode

FA is for Fast Process which is essentially target separation at its best in a search mode. This is a new search mode that provides faster target separation with shorter audio durations to quickly identify good targets that are adjacent to junk items. This mode is especially useful for trash-laden terrains.

How good is it? Hobbyists have reported excellent target identification with coins having been found in the same plug as rusty nails. They swear they heard the good tone, dug, and found the good item amongst trash. Positive target identification, fast recovery – it’s a fine metal detector indeed.

FeTone Volume Feature

New tone options have been added to the Fisher F75, but one of the many available is FeTone. This setting may hold a lot of value to the treasure hunter. The FeTone offers three settings of 2F, 2H, and 2L, all of which have two tones: low and high.

2F has a low tone on iron objects regardless of its signal strength. 2H works the same but iron targets have low volume with 2L sounding off iron objects at a very low volume.

The FeTone volume feature is exceptionally useful for those who want to hear tones on all targets, including iron, but don’t want to get worn out by hearing it at the same volume level of non-ferrous targets – it’s sounding off, but in the background at low volume.

Ergonomic & Balanced

The Fisher F75 is a very well-balanced metal detector that weighs in at 3.5 lbs. It’s certainly not as light as other metal detectors, but due to its ergonomic and balanced build, it’s much easier to handle than a nose-heavy metal detector that may be lighter in weight.

It appears that previous models had an adjustable armrest, but the latest models do not have that option.

Made in the USA & Warranty

The Fisher F75 metal detector is made in the USA. It has imported parts, but it’s completely assembled and sold out of the factory in the United States.

Even better, it wipes the competition on warranty. It offers a 5-year warranty that beats most other warranties that only offer a one or two year warranty. You need to keep your original receipt as it is your proof of purchase, and it is not owner transferable.

Filling out the warranty registration at Fisherlab’s website also puts you into a free drawing to win a metal detector that is drawn twice a year. How’s that for incentive for registering your newly-purchased metal detector?


Steep Learning Curve

It doesn’t have too much of a steep learning curve, but some impatient and inexperienced hobbyists have been unable to use the Fisher F75 to its maximum potential.

It’s true that a learning curve is required, and it does take some time to learn the “language” of this metal detector and all its features, so it goes without saying that you must read the included manual. It will provide an in-depth explanation of its features with instructions on how to use them.

Other than this, there are little to no complaints about the legitimacy of its functionality and performance.

Popular Questions

Is the Fisher F75 the Newest Model?

After 2014, Fisher F75 metal detectors feature DST, FeTone, and FA in all their standard F75 models. There are also two additional models in the F75 series, the F75+ and the F75 Ltd.

The F75+ features the Boost Process which is a search mode that improves maximum depth detection in most grounds. It also comes with the F-Pulse waterproof pinpointer in the package.

The F75 Ltd. has both Boost and Cache Processes that improves maximum depth detection and detection of large targets for relic hunters. It also comes with both 11” DD and 5” DD searchcoils.

Is the Fisher F75 Metal Detector Waterproof with a Lighted Display?

The searchcoil and shaft are the only waterproof components of the metal detector. You can use it in shallow water, but a rain cover for the control box is necessary to protect it in this type of terrain. Even so, the coverups are not submersible.

The F75 does have a single brightness backlit display that cannot be turned off. It’s unnoticeable during the day and is provided for visibility in low-light and night conditions – not for underwater use.

What Type of Batteries does the Fisher Metal Detector Use?

The Fisher F75 requires 4x AA batteries to operate. It can be used with both alkaline and rechargeable batteries. Rechargeable batteries that are not compatible with the F75 include zinc-carbon batteries.

With alkaline batteries, you can get up to 40 hours of operation. With rechargeable batteries, it will operate for approximately 25 hours.

What Accessories are Included with the Fisher F75?

The only accessories included with the standard Fisher F75 is the 11” bi-axial searchcoil and a cover for the control box housing. A skidplate, headphones, and batteries must be purchased separately.

How Deep can the Fisher Metal Detector Detect?

The F75 is known to be very good at detecting small coins, even as small as a dime. As far as depth, there are many factors that determine its maximum depth detection. Owners have been able to detect coins as deep as 8” to 16”. It’s proven to have found coins adjacent to other items, deep coins, and gold jewelry at good depths.


The Fisher F75 metal detector may be lacking in included accessories, but all the investment is in the performance of the metal detector itself. With the additional features, you’ll be able to finetune your tool for maximum performance wherever your leads take you.

For the record, it does very well in wet sand with all its adjustable features even though it’s not made specifically for the beach. So, saltwater environments will be viable hunting grounds in your future.

With room to grow, skills to develop, and a quality machine that can see you through it all, it’s worth the investment even if you do have to buy headphones on the side.
