Fisher F5 Review
Okay…are
you ready for this? I’m going to open this F5 review with a very bold statement.
The new Fisher F5 has the BEST user interface of ANY metal detector I’ve ever
used!..and I’ve used a bunch!
The Fisher F5
is yet another weapon in Fisher’s ongoing “War on bad ergonomics and interfaces”
that tends to plague the hobby industry. The absolute brilliance of the design
makes me wonder “why in the world hasn’t someone already done this?” Sure…hobby
detectors have used knobs in the past to control functions (like Fisher’s
own venerable CZ series), but never before has there been this perfect storm
of digital, software driven power combined with the ease of tactile knob control.
The F5 knob settings
are instantly relayed to the user in a window in the bottom left of the display
(settings). When you give the gain a tweak, the window intelligently switches
to the gain setting… adjust the ground balance, it shows you that too! The
same goes for Threshold, Discrimination, Tones and more. When you’re not adjusting
something, the window displays the current ground “phase” setting. It’s a
great concept… all adjustments can be made on the fly, and you’re instantly
informed on what you’re changing (and by how much).
Each of the knobs
on the F5 is strategically placed so you can “thumb” the controls. If I hear
a deep target that is on the fringe of detection, I don’t have to dig through
layers of menus to adjust the gain or threshold…a quick reach with the thumb
of my detecting hand and I can ease the controls up quickly and efficiently!
When I’m done, it’s a very simple task to “thumb” it right back to my starting
point…
Speaking of gain
and threshold, the F5 puts these to control knobs side-by-side for a reason.
There is a very synergistic relationship that has to be seen to be believed!
High gain or high threshold…which will be best for my current hunting site?
The flexibility offered for adapting to all your various hunt sites and their
challenges are incredible. There is a local farm that I hunt that is surrounded
by an electric cattle fence. I have had to hunt this spot with ridiculously
low settings on older detectors just to make it bearable. With the F5, I can
adjust the Threshold control to around -1 or -2 and still get very impressive
depths!… without the noise and chatter this spot usually bombards me with.
Since using the F5 in this pasture, I’ve recovered several old silver coins
that I just could not hear with my older detectors!
The threshold
control also does something else. Have you ever hunted a site that drove you
nuts due to tiny bits of foil, rusted tin, etc.? By lowering the Threshold
control, you can partially eliminate the F5’s sensitivity to ‘em! As a precaution,
I tested this in my coin garden to see if it would have a major impact on
the depth I could get coin sized targets. Although there was a very slight
loss of depth, I was still able to hear coin sized stuff within about ½ of
an inch of the “zero” setting on the threshold (this was adjusting the threshold
to around -2 or -3…plenty to get rid of the tiny stuff on most sites).
The audio on the
F5 is amazingly descriptive. You have the option to choose single, two, three
or four tones. However, there’s a lot more to the F5 audio than just the number
of tones! There are some amazing tonal qualities that change according the
cleanness of the signal, proximity to other targets, tone mode selected, etc.
I’m reminded of a few old analog detectors I’ve owned that although 1 tone,
gave me a lot of information about the target due to the “little things” you
hear in the audio. In other words, there’s much more going on here than just
“BEEP!” on a target.
Another super-cool
feature on the F5 is the “Phase lock” button. I mentioned earlier that the
F5 has a brilliant user interface. The F5 is also spectacular in another area…
user information! The F5 feeds the hunter with important data in “real time”.
The “Phase lock” button allows you to “grab” one of these real-time bits of
information…the phase reading! Phase and ground balance are nearly synonymous
(at least in practical use terms). While hunting, you can glance at the “phase”
reading on the right, and if it is several numbers off from the static ground
balance reading in the “Setting” window, you have two options. One is to manually
tweak the GND BAL knob to match the setting, or my favorite method, a quick
press of the “Phase Lock” button, and it’s set for you!
You have the usual
TID (target identification) on the big, clear LCD screen, but you also have
other key bits of intelligence streaming to you. One is the Fe3O4 bar on the
GND DATA window on the right. This tells the user about the amount of “magnetite”
in the soil, which can affect the accuracy of the target ID circuits in the
F5. The other is the previously mentioned “PHASE” reading, and lastly there’s
the CONFIDENCE bar. The bar tells me how “sure” is the detector that the target
identified along the TID arc (Fe, Foil, Tab, 5ct, etc.) is indeed what it
says it is. It is yet another piece of information for the user to add to
his/her list of “evidence” when investigating a possible goody! Really deep
targets, and targets partially “masked” by other junk items can fool even
the best, so good practice is “when in doubt…DIG!”.
Hunting with the
F5 is sheer, ecstatic joy! The weight and balance are great…the controls intuitive
and useful…the ground and target information…actually practical! Minutes can
turn into hours while hunting without the usual fatigue setting in…a testimony
to a metal detector that has both the physical stuff right (weight, balance
and ergonomics) , as well as the abstract stuff… (Can I call it “mental and
emotional fatigue?). I have hunted with detectors in the past that “wore me
out!” both physically and mentally due to bad physical design, constant chatter
and horrible menu systems that made you have to dig through layer after layer
to change something. NOT so with the F5!
F5 features:
* Tremendous battery
life (I’ve gotten over 40 hours from a pair of 9 volt batteries!)
* Incredibly descriptive adjustable audio ID (1 tone, 2 tones, 2 tones or
4 tones)…tones also adjustable in All-metal mode
* Great in-ground depth performance
* Very accurate target ID at depth
* Visual target ID while in all-metal mode
* Brilliant user interface
* Tons of useful ground/target information in real time
* Nice big LCD display
* Solid construction and materials
* Great and simple NOTCH feature for eliminating (or adding) targets
* Excellent elliptical concentric coil
* Included Velcro cable and arm cup straps!
* Frequency adjustment for hunting near other detectors or electric fences,
power lines, etc.
Summary
The new Fisher
F5 is a metal detector that will set a benchmark for it’s incredibly well
designed interface. I can see new Metal Detectorists and Veterans having a
blast with it, as well as anyone who just likes the feel of knobs better than
button pushing their way through menus. All the control is there for the power
user…but in a whole new way! “Simple…yet intelligent” may sum up the F5 quite
well! I find it quite ironic that Fisher Labs, the “Oldest name in Metal Detecting”
is on the cutting edge of the newest technology! I very vigorously tip my
hat to Jorge Anton Saad who was Lead Engineer on the F5 project…and well supported
by the legendary Dave Johnson, John Gardiner and Mark Krieger. A job well
done on what is sure to become a favorite metal detector for a lot of people!
