F75-Calm down everyone

[ronhob]

I think everyone needs to step back and realize just how good the depth results are. The mama bug and AM depth on a number of these machines was obviously bad, but now everyone is in a panic that their machine isn't up to par. Go do a few air tests against another detector if you have one. These machines are deep and quite... What someone else says is 14", I might consider to be 12" Lot's of difference in what people consider a good response in a air test. Some people's 16" whisper can't even be heard by others. Just a thought.

So is the mama bug & lack of AM depth an issue that needs rectifying to make this machine good? I have both of these, mama bug doesn't really bother me but I'm not that impressed with how good this machine should supposedly be in AM mode. Think I'll contact my supplier for advice.

Mama bug was with the 11/14 only i was told, but if some of the circuit board's in the upgraded unit's aren't taking all the software upgrades you might be missing out on some of the other upgrade's other than the AM depth issues. Hopefully the circuit board will take care of my issues. This is the 2nd return for these problems. So reading other posts here disc and am air-test should be close not 4-5'' less in depth for am right, that's a Big difference. If you can hear 15'' in disc you should be able to hear that in am.

I read Mike Scott's statement several times. It does say he encourages all those with issues to return the unit for repair.
So I will make the call next week and ask the fix my Ma Ma problem.
That way I can calm down and put this issue behind me.

 

[cintitomcat]

Make if you have a am depth issue you tell them or they wont check it.

In am sense 85 no bp bp is too unstable on the bench to hear the dime at sense 85. On my etrac man sense 27 stock pro coil I get the same dime 13.5ins. I can get a whisper on the 75 at 12.5. And at 14 on the etrac. I'm thinking that's not bad on either unit. If you get 12 ins on a silver dime in am at sense 85. That's plenty. As far as upgrades I'm not running an upgraded unit. I have never dug a dime at 12 ins with either unit but have found large coppers close too that. With both. HH c t

I let my buddy who only has a e-trac use my new F75ltd2 in AM mode to show him how quiet it is.
He was impressed. Especially finding a token, skelten key, and 1800 wheel from a old toy that the e-trac missed. I have owned the V3i and it air tests good but not good in the soil. My etrac buddy told
me the e-trac does not do good in air tests but does need in the ground.

I did an experiment last night. I placed my detector in three different locations in the house and set it to both DISC in JE, Sens 96 (the most I could get all three spots stable) and then did All Metal with the threshold just below perky. All with Black Widow headphones. Ground balance unchanged for all (default). 9.0 version. All were with the detector at about 28" off floor on wood stool

Kitchen (laundry room below). Nickel 10.5" solid hits DISC, 11.5" solid hits AM.

Den near TV and desk-top PC (furnace below). Nickel 6.5" solid hits DISC, 8" AM.

Mud room (cement slab below). Nickel 12" solid hits DISC, 13" AM.

By solid hits I mean repeatable both directions of the sweep.

To me this solves one mystery - selection of test area makes a BIG difference for my detector. Your house may vary - but I got poor results near the TV (that was on) and the PC (also on). Those of you getting sucky results - try a different room or try outdoors.

I was testing mine out in a field a couple hundred yards from the house. Went through all frequencies to find the quietest one (they were all quiet). Disc mode is strong, AM mode is anemic....9.5" on a quarter vs 14" in BP mode. In fact all of the disc modes are way better than AM mode. Something seems amiss here. When you add disc you lose depth....no???

Charlie ive noticed the same..silent emi makes a huge difference

I have heard that the fbs units need ground matrix but honestly I can't say it's so! And I too have gone over areas that I have done with fbs units and the fisher found a mercury. A little league pin says coach. And a small junk ring. All missed. But seen and found by the f75. Again I love the f75 it just plain works!!! Now the upgraded version I do not own so I can't comment. I firmly believe if you learn you're machine. They're all good!!! It's just it needs to become an extension of you're ears. I know a fellow that still hunts with his red baron unit. And consistently. Finds great stuff. Well I guess these upgrades need some tweaks it seems that if you have 10 of the same say laptop computer and you put the exact same os into them all. They should all work the same. Now I know that detector companies. Fisher for one might buy say the lcd. From more than one manufacturer. So perhaps other components from one manufacturer. This month. Then same components. From a different manufacturer next month with a slightly different tolerance just slightly different in spec. Would cause as a whole in circuit a bit of preformance difference. I'm sure the camo 75 will have some different manufactures. Part even though it's the same!!! Thanks would the 75 black se. Herein lies the problem. I believe it's impossible. To think every upgraded unit will function the same. OK done rambling. Best of luck to all HH c t

Huh??? Would you repeat that again slowly please????

Upgraded units would function the same unless they were in the same production run. And then the amt of use coil wear. Coil windings etc would play a part. 2 69 Chevy impalas one has 20'000 mi the other 150'000 mi. And you added the same preformance manifold carb. And exhaust. They most likely wouldn't run the 1/4 in the same time bracket. Wear and components make a difference. Can You Tell its winter here and the depressing snow is falling? Yup gives me plenty of time to ramble. Both Mike Scott and Felix Cavillo. Have been great in helping me out over the yrs and I firmly believe both will do whatever it takes to satisfy loyal Fisher users. But unless every unit has their master board and coil replaced. With the identical in every unit no two will act or react the same. The f75 the t2 the eurotek the f19 all very good machines get out into the field use them and if you feel there is truly something amiss heck send it in those guys at fisher aim to please. HH.

I know you have had a great deal of experience with the Fisher line. Also you have had some repaired ,and know what the results are of a proper working machine.
Again thanks for posting your opinion and your knowledge.

New member here.... Jason is the name. I'm a relative newb to detecting as well, been swinging an Ace 350 and a couple of other entry level machines for about two years. I've come to realize I'm simply not getting enough depth to really be an effective detector. I've been studying and pondering on an F75 upgrade purchase. I'm about 6 or 7 pages into the F-Series forum when I found the above response. Decided I'd join up just so I could say Good Job Charlie P!! I know it's not some deep prophetic post, but it's the simplest things that make the difference sometimes. And sometimes they are the easiest things to overlook. After 6 or 7 pages, I've noticed you and a few others are constantly giving good sound advise,,,,,Great job keeping it real!

I have found some good finds with this machine. I go back and forth between the Etrac and F75ltd2 to clean out a lot. The F75 has found some good stuff. It is deep and if you have some decent ground it rings ups solid numbers. for me the etracs pulls out the silver and the f75 nails he indians, large cents and cool relics. For me it is perfect. One thing I noticed you can turn up the discrimination to around 50 nd still get nickel signals at around 30 vdis with no notch. It looks past the iron and hits the low conductive. When I turn up the discrimination to around 50 the signal omes in better and stable. Anybody else notice that?
