Does anyone understand the NOTCH system on the F75 ?

[saamdigger]

The manual gives some examples of notch and disc settings that defy understanding. When you engage the notch it never changes until you do a reset! You can change settings but it is like it doesn't take .I need a lot of clarification if someone understands the system.

Try here it explains it pretty clear

It's still not clear to me. If I set a notch setting and then run for a while and change the notch again the items with a line through them do not change state....................they still have a line thriogh them and all I have done is add other notch items to the list.If I do a reset then all is erased.If you mix notch and disc you don't what you will get.

I would print this out & have the detector in front of you to practice on. Good luck because you're going to need it!

You have to do a reset every time you want to change the notch setting ?

That's why I don't mess with it. Just set discrim on 6ish and leave the Notch alone!

I understood what was trying to be accomplished by the designer. But the implementation ended up convoluted. They should have just removed notching and not tried to make a coin hunter out of it or come up with a better interface. Though the Edge worked on a somewhat similar scheme it had a series of preset notches, which though having lower resolution were much easier to set.

As the industry moves more towards digital interfaces, the display adjustment/display schemes will need further attention. Attempts at over simplification with singular joystick and multi-layer sub-menus lead to more complexity for the operator. As evidenced by a couple responses to this thread some users just throw up their hands.

I have been watching with some interest the reaction of average users to the V3 interface. I am curious as to how many believe that they will ever truly master it, how long it will take them, and what their ROI for the effort will be? Wrongly, I thought a lesson had been learned with the DFX concerning very involved interfaces.

i agree!..not needed!..

one quickly realizes that the 75 can be "set" a certain way for "most" applications,thus notch is of little importance!

yes I have with the F70 run into the dead end, where the notching wont cooperate right without a reset. I do it right when I start out for the day, I like notching the nickle back in after discriminating out the lower metals, tabs, screw tops, etc. I wrote down my favorite setting ahead of time.

I plan on getting one later on, made up my mind....HH John

Use one or two tones, set the Discrimination low and Sensitivity to where it just chatters. Let your ears do the discriminating. At first you will think there is something wrong with the detector because of all the noise you will hear. But that's just because it's the fastest most sensitive detector on the planet and you are hearing every little bit of metal in the ground.(Insert Parrot smiley here.)

If notching is of little importance then why did FT include the feature? After the F75 the following detectors were designed WITH a notch feature:

F2
F4
F5
F70

Delta
Gamma
Omega

Was all of that effort & expense a waste of FT's time? As shocking as it may come to you Metal Detectors get used for more than relic hunting. In areas with a heavy infestation of a consistent ID trash target, notching can prevent audio fatigue and save time.

If you are going to use an F75 as a beep/dig relic detector then you just spent a whole lot of money for a Tejon with a meter. Why pay for features & complexity that you will never use? Let me guess the answer: "because it's the fastest most sensitive detector on the planet". Well........I've tested the stock F70 against several other detectors and it's no faster, just noisier. Maybe I have a Monday morning F70 that they forgot to put the Tabasco sauce in.

Glib replies lead to glibbier replies.

Here, here........................what he said. The source of my irritation is that the manuf doesn't take the time to explain fully the use of the detector or designs it so complex that it leaves most users behind.

is that owners manuals can't be and therefore aren't the initial and final all knowing all telling recipe for instant competence. They're nothing more than a starting point for an individual to digest to some various degree. You go from there to actually acquiring the important learning, which results in developing true skill, through DOING. Manuals run the gamut of the too vague to the informantion overload ad nauseum extreme. How could a writer possible word something in a manner that would insure quick comprehension for all individuals? I understand how some are frustrated as they try and learn the F-75's notch system. I learned mine by just glancing over the info in the manual and then sat down and actually learned how it works by trial and error playing around, or primarily self taught if you prefer. It took exactly 24 ounces of an adult beverage. Relax, learn at your own pace, and accept that is okay and as good as it gets. Even though so many of the good old finds are and have always been finite, there will still be some out there with your name on them if you have PATIENCE and do the work to make it happen. I don't know if anyone else has noticed or agrees, but I'm sorta thinking this whole instant gratification need in our society isn't serving anyone very well.

i liked the first part of your paragraph!..tones and the speed of the processor does it for me!..happy with that!..great detector!

this is certainly true.however like everything else in life,if ya really WANT to learn it,then you will!..i can understand why fisher would include the notch on a high end detector,however i am havin' a ball just using the tone(s) and v.d.i which gets it done for me!
