A Video and written review of Fisher's F75 Metal Detector
This review starts off with a video of overview of the F75. The video helps a lot because it gives you a good feel for the LCD interface on the F75 and its key features. We then follow that up with a written review of this professional class, multi use metal detector with full LCD screen for easy target Identification. As with many Professional Class detectors this can be used for specific hunting like gold, coins and jewelry, relic etc. You can click on this link to read a review of the Garrett GTI 2500 Pro Metal detector to compare the Fisher F75 against another detector in the Professional Metal Detector Class. Note that the Fisher F75 is virtually the same as the Teknetics T2 Metal detector.
F75 Video Overview
This Treasure Hunting Machine was designed from the ground up for the specific purpose of finding deep targets, even among trash, better then any other metal detector in its class while still providing all the features and benefits of the every day detector. As a result it is not just a "Detector X, version II" but a true uniquely designed Metal Detector that does exactly what it claims.
The Fisher F75 Metal Detector Really does find coins in the 15" range and even below (depending on the soil conditions of course). While the average weekend hunter may never use that depth capability it is great for the pro hunting out "hunted out areas" or the battlefield relic hunter or for fields that have been plowed etc.
The reason I say the "Average" weekend hunter may not use the depth is The average hunter may not have the knowledge and ability to even dig up a coin from a foot and a half down. I have seen detectorists get frustrated trying to dig AND find a target deep down and they finally decide its a false signal and give up. Why? Because most do not have a Pin Pointer (a small hand held metal detector shaped like a large screw driver or curling iron that can pin point the location of a target in a pile of dirt or sand or in a hole. Also the target can get pushed around by the digging, pushed on edge or even underneath a piece of junk.
BUT the Fisher F75 is great at finding deep treasure and is loaded with features. So it does what it claims!
Fisher F75 Metal Detector – Details and Specifications
I am going to break the Fisher F75 Metal Detector features into 2 categories – those that are really Unique capabilities and those that are just specifications or features that are not out of the norm.
Outstanding Features and Capabilities:
Ok, normally I would not list a detectors "user interface" as an outstanding feature. But check out the picture of the Fisher F75 Metal Detector's control unit below> Now what stands out? Two things:
1) It is large and easy to read. This is great. so many detectors have crappy little LCD's that you can barely read.
2) IT IS NOT COMPLICATED. I can show you pictures of some Metal detectors in this class with 8 knobs and switches. What a pain. The Fisher F75 Metal Detector is driven by menus just like on a computer or cell phone and the menus are always displayed so it is easy to get around in.
The second Main feature I will point out for the Fisher F75 Metal Detector is its ability to find DEEP Targets and to discriminate between trash and treasure at depth and to target the treasure at extreme depth! Here are a list of things that enable that to happen. This is mostly technical stuff
- Double-Filter Discrimination Modes for Searching in Trashy Areas
- Search coil: 11” (28 cm) open-frame elliptical double-D, waterproof.
- Operating Principle: VLF induction balance
- Operating Frequency: nominal 13 kHz, quartz crystal timing reference
- Basic Sensitivity: 6 x 10 9 root Hertz ()
- Lag Coefficient: 78 milliseconds
- Reactive Overload: approximately 10,000 micro-cgs units (volume susceptibility)
40,000 micro-cgs units with sensitivity < 30.
Resistive Overload: approximately 1,200 micro-cgs units (volume susceptibility)
4,800 micro-cgs units with sensitivity < 30.
- Ground Balancing Range: From ferrite to salt, inclusive
- Discrimination Ground Suppression: combination of second and third order methods
- ID Ground Suppression: third order
Other Features and Specifications
- Mechanical: The F75 has an S-rod design with electronics housing mounted on handgrip, 3-piece breakdown, batteries under elbow, 2-way armrest adjustment forward/backward & around forearm.
- It only uses 4 Batteries: 4 AA, alkaline (included) but has excellent Battery Life: Typically 40 hours with high quality alkaline batteries
Estimated 80 hours with nickel hydroxide batteries
Estimated 65 hours with lithium iron disulfide batteries
- Weight: 3.5 pounds (1.6 kg) with alkaline batteries installed. This is pretty lightweight for a detector with all these features.
- The detectors balance decreases the stress on your muscles: force in vertical plane normal to elbow 0.47 pounds (0.22 kg).Varies with adjustment and user’s stance and arm/hand physiology. The Dynamic Balance: axial moment, 0.29 foot-pounds (0.39 newton-meters). Varies with adjustment and user’s stance and arm/hand physiology.
- Operating Temp Range: 4 to +122 degrees F (-20 to +50 degrees C)
- Operating Humidity Range: 0-90% non-condensing. I am not nuts about this. I like detectors to be moisture resistant. I couldn't use this on half the summer days in a humid climate.
- Lightest Weight / Best Ergonomics in the Industry – (So they claim. I have never measured it)
- Powerful Performance Trigger-Actuated Target Pinpointing with Variable Audio Pitch
- Large LCD Screen with 0-99 Numeric Target Identification Display - EXCELLENT as stated above!
- Magnetic Mineralization Bar Graph and Readout – few have this
- Trigger-Actuated FASTGRAB™ Ground Balance
- Non-Volatile Memory Saves Settings
- Backlight – For Low Light Hunting Conditions – I would expect this on any detector with a large LCD screen.
- Low Operating Cost – Typically 40+ Hours with 4-AA Alkaline Batteries
- Double-D Waterproof Search Coil An excellent coil
- Rain Cover for Control Housing & Battery Housing Available
