Well, after 7 yrs I'm back in the hobby. Still have my XLT and 1280X but feel like I need more of an edge. Enjoyed the posts on this forum and used the info to decide on a new machine. Had considered the ML but something about the F75 drew me in like a magnet. Maybe it was the posts on multiple freqs. for stability making the ground light up? Maybe it's because I'm getting older and the ML would be heavy? Not sure but ordered the F75 and small coil today.

There have been times when I was not convinced that something I had ordered was the right move. This is not one of those times. Can't wait to get my hands on the machine. I've read and reread the manual several times and I'm already thinking about experimenting with multiple freqs. multiple tones, etc. I'm ready for my first gold coin. The F75 is going to help me find it!

Hi there Ron......... I'm curious about the wording of parts of your post. (Highlighted in red)

I hope you are not under the impression that the F75 is a multi-frequency detector...in terms of its transmissions..???

It's a single frequency unit, (approx. 13 KHz) whose operating frequency can be slightly altered to alleviate co-interference. It does have 'tone ID' features...........MattR.UK.

Hi Matt:

I guess my post was a little ambiguous regarding the multiple freq. thing. I'm aware that the F75 operates on just one frequency. Somewhere on this forum there is a post where a member describes changing the operating frequency to stabilize the machine and achieved not only stability but also an increased sensitivity to previously undetected targets. So just because the machine is quiet doesn't necessarily mean it's totally stabilized. Might not be a bad idea to change frequencies, back and forth before a hunt, to find the frequency that provides the most stability. Just a thought.

Enjoy reading your posts and I go back a reread them from time to time. I'm XLT trained so it will take a while to make the jump to the F75.

Glad you came back to a great hobby & picked an excellent detector to do so.....
Just take it slow as the F75 is full of power. Don't be afraid to run your sensitivity about 50 until you are comfortable, & best of luck finding your first gold coin! The F75 helped me find mine & it's very hot on gold.....
HH,
Bill

Hi Bill:

Thanks for the welcome to the forum. Appreciate your efforts to put together this forum for the F75 folks. Lots of old stuff here in Wyoming, just need to get the F75 over the top of it. One of my hobbies is reading the old Cheyenne newspapers (c.1867) on microfilm. Folks back then didn't need much of an excuse to have a gathering and took the opportunity to do so regularly. Excellent source for leads on old sites.

I've focused my attention on finding a $5 gold piece out here. Any other gold will do just fine but I'm concentrating on the half eagle. Maybe you could share the settings and the story of your gold coin find? So far I've located an old picnic area, an old race track and an old swimming hole; all of which are probably virgin. Problem is; these sites are located on property owned by huge companies. As the weather gets more favorable I'll make an appointment to talk with the companies and ask for permission to hunt the area.

My understanding is that my F75 should ship today or tomorrow. We've received quite a bit of snow but there's an upside, I suppose. From time to time we get a lengthy thaw here and my hope is that the snow, and its moisture content, will act as a blanket to keep the ground from freezing too hard to hunt. My six acres are number 1 on my F75 hit list. Wagon trains and Cavalry soldiers used to cross this area headed West toward the town of Laramie. That's the fun of it; I just don't know what's out there.

Really interested to see what the F75 has to say about the soil conditions here. Wondering if any of the more experienced F75 folks might take a look at the seven frequency adjustments as a way to enhance the performance of the F75, stability wise. Obviously, if you can switch to one of those freqs. to quiet down the machine, it tells me that there could be one best freq. for the area being hunted. True that you might not hear the difference in the headset but maybe another easy way might be found to determine if there is one freq. better than the others for the hunted site. Time for lunch.

I understand what you are saying about the freq. shift, and you may be right. I've both experienced that with my T2 and heard the same thing from F75 owners. Don't hesitate to toy with the freq. to optimize your chances. And be sure to let us know how it works out.

Matt you must have missed the posts about the 12th of November. They did suggest that the fractional frequency changes that you can do with the F75/T2 acted the same as switching from say a 5 kHz to an 18 kHz machine. I did point out the true situation on the 15th when I noticed it.

 

[MattR]

Hello Brian....thanks for the info.

Can you expand on matters...who said what, and on which forum?.....Matt.

 

[vlad]

On multiple frequency detectors this causes a higher power drain, so the makers generally cut back on the TX POWER. While multis may have advantages in some situations, its not across the board for everyone. Talk to TINFOIL on the F-75 on Florida. black sand beaches where it worked PERFECTLY, and he could not even get others including multis to ground balance.
You can put the DMC-2b and the TREASURE BARON with DEEPHUNTER MODULE on full boost, and they will blast ANY VLF on the market [both are singles]. I think you will find the F-75 a real BLASTER also-and extremely simple to use.
[On this detector do you mean ALT. FREQUENCIES?]

 

[Jackalope]

Take a look at the post; Changing Frequencies. What exactly is it doing? on Nov. 12, 2007

Hi there Vlad......Parts of your post are in my opinion, a little inaccurate for general consumption. I've highlighted the questionable sections.

Your statements on multi-frequency detector implies that they 'use more power' than conventional CW (continuous wave) units. That is too general, and not backed up by any 'for example' quotes of makes and models. Such info would add weight to your assertions, and be very informative, as far as I am concerned.

Where do you get this information from?..........Manufacturers of these unit therefor 'cut back' on power...............?????????????

Also you refer to Tinfoil's beach work......................The F75 works perfectly.............????????????


**************************************

I have read Tinfoil's posts regarding the F75. Indeed he did imply it worked OK, but I feel that he was talking relatively. To use the phrase 'perfectly' is I think a little too much over the top.

It obviously did indeed work, but only to some limited degree, when apparently others did not.......Again, no identifying of 'the other machines' leaves the statement in the 'vague' category.

Now to deal with the 'power' statements by your good self.

Nobody, unless they have the manufacturer's data, or are professionally capable, using the appropriate equipment, can tell what the power expenditure is, of any detector.

There is RMS power and PEAK power. Which are you using as your reference?

Can you quote ANY figures that may be of help to either me or the forum readers?

Finally. The few 'multi-frequency' detectors that I've 'superficially' monitored. ('scoped their waveforms), have all been pulsed wave-forms.

The F75 is CW (continuous wave).................

Any further expansion of thoughts on the original comments, V?..................Matt

Hello folks, did this ever get resolved? Thanks, M.

 

[vlad]

TINFOIL told me it worked, "PERFECTLY ON FLORIDA BEACHES", in person.
As to power consumption of multis vs. singles, my sources are Mr.Bill, George Paine, and Eric Foster.

For an example of TX power, I cannot get anywhere near the depth from a DFX that I can get from an XLT,and I used every frequency method, amount of filters and the various sensitivity settings & recovery speeds-these two detectors used SIDE BY SIDE. You are right, no one publishes electronic specs., except Nautilus, & Discovery on the Treasure Baron Deephunter module. These allows most makers to hide in the vagueness of terms like "[most] powerful" instead of publishing exact figures.
Of course someone like Mr.Bill or Ty Brooke who has the equipment could tell you the parameters, EXACTLY.

 

[vlad]

I was also told the same thing about power consumption by Ty Brooke & Georgi Chaushev.
Its, "ELEMENTARY MY DEAR WATSON" that transmitting on more frequencies uses more power-basic physics.
As to RWS or PEAK POWER I use REAL WORLD EXPERIENCE which is Scientific Fact that I can duplicate, and NOT an OPINION-THERE IS A DIFFERENCE. TINFOIL owns 14 detectors, so the word PERFECTLY coming from him is NOT A RELATIVE WORD. Jerry knows his detectors, what works, what does not, and is not hesitant about what HE HAS EXPERIENCED [FACT NOT OPINION.]
And I never said ALL multis are cut back on TX power, you found that implication where it did not exist [I should have said "can be"]. I use among other detectors a CZ-70Pro which is one of the deepest, and get about 12 hours out of the batteries-compare that to an F-75 or a 1236X. I think people using the CZs and Explorers will all confirm great depth from high sensitivity machines. As to Exp/SE batteries, I do not know their setup, but I bet the X-Terras have more battery life.

 

[Jackalope]

Let's see if we can't get back on track here. My reference to multiple freqs. at the start of this thread was meant to discuss the 7 selectable alternate frequencies provided in the F75 in case of electrical interference, etc. I later made a reference to a past post that talked about this.

Ron

 

[UK Brian]

Sorry not to have seen the posts before (I sold the F75 and kept a T2). There was a few posts on different forums based on the "change frequency and light up targets" post on this forum 12th November (changing frequencies. What exactly does it do ?).

Brian

 

[iliketodigit]

Hello Brian, found the post you referred to from November and it was very interesting.
Having that added feature may well prove useful.

If i was in an area where interference was present i would approach it this way.
1. Try and find which frequency setting was the worst affected.
2. That done if it was say setting F2.
3. Change the setting to the furthest away in this example it would be to F7.

Having only just got my F75 I'm probably talking daft!!
This forum is going to be priceless for a F75 newbie like me.

Did you think that the T2 was better suited to our UK conditions for you to let the F75 go?
Thanks, Mart.

************************************************************

Dear Vlad. Your replies to-date, clearly indicate you have no scientific or technical understanding of the matters you try to convey to others.

Your answers are repeatedly punctuated with phrases that imply other knowledgeable people 'Told you so'..........i.e."told me".

That may be true, or it may be your way of expressing the fact that you actually read it somewhere. Whatever the method, you clearly are not able to assimilate their attempts to educate you in the subject matter.

To me, you portray someone trying to appear knowledgeable about the technicalities (not the use of) detectors, but lacking the necessary understanding, you bluff and mask the fact by repeatedly quoting the names of others who are capable.

Try writing a post on the points involved, without involving any body else, and giving only your thoughts on the matters.

Also, seeing how you are fond of 'scientific facts'.....Please explain to the forum readers how YOU can prove your statements and understanding of POWER DISSIPATION in both multi-frequency and single frequency detectors.

Be it by circuit diagram, your own drawings, or any mathematical treaties which you are able to expand upon.

Alternatively....Produce evidence/copies of the information to which you glibly referred to; from Eric Foster, George Paine, Bill, etc.

What is not acceptable, is 'hearsay' or waffle..................MattR.UK.
