F75 Camo upgrades

Got it back a few weeks ago and just tried tonight, all connections are tight, 9.0-9.1. This thing sounds worst, i couldn't hunt with this if i wanted to. maybe i'm doing something wrong, turned on, made setting bp, sens 99, tone 3h, tried this in 9.0 and 9.1 no different.
 
i dont have the camo unit..but mine is super quiet..cant even tell its on half the time..i use the same settings as well
 
Mine is exceptionally quiet. My first impression is a connection or loose coil in some way. Something that would be across the spectrum of the machine. Did you change the coil or connect/disconnect it after getting it back? I would take the coil off and ensure the connection is ok. Then, if all is OK, I suggest you take it out of bp, and try de. Just take it outside the house, turn it on, set disc at about 15, sense at 80, mode in de, and see what happens. If you have a dealer nearby take it there and see what they say. Then if it is still screwy, I would send it back.
 
Before my upgrade I can't recall trying to use mine indoors in the house. I have used it in the front and back yards but never over a sensitivity of 40.
After the up grade testing in the house is not possible due to EMI unless I go to the basement. And then I get a bit of chatter in the default mode in 9.0
I notice the default mode sets ground balance at 90. This is way to high for me so I have to do a ground balance every time I do a reset. If there is allot of chatter when I turn it on it does not seem to do the auto grab well. You have to find a quieter spot or do a manual GB.
I have no EMI issues in the field yet.
My impression is my unit came back "Hotter" or at least much faster than it was before.
My Testo Compadre acts the same way in the house. Very noisey so I think that is normal.
 
Tried outside yesterday and no difference, went out again today in my backyard and removed coil cable and reinstalled and it seems better but not what i was expecting. I had sent the detector in about 2 months ago for a checkup and they replaced the toggle switch and coil connector. I only pulled it out of the box to try then repacked it, it's been in the box right up to the time i sent it in for upgrades. Seems quieter when moving around on the ground then it was before. I will have to find someone close that had this done to let them try it. Maybe its working right but still would'nt pick it up over my E-trac. Thanks for the feedback Tom
 
I took mine out for a three hour hunt this afternoon and had the best day ever. Found my first ever 1897 Silver Coin, A watch band, A 1944 Wheat, and a 74 Kennedy Half dollar, two Clad Quarters, Three Clad dimes and a few pennies.
I hope you get yours figured out soon.
 
Did they leave the came faceplate on yours? I was reading another thread about a guy who sent his camo F75 in and shortly after Fisher recieving it he got a phone call from them and they said if he wants the new upgrade that they will need to swap out the camo faceplate for a black one. ???
 
I got the same call, they don't have upgrades to match the camo so they call to see if you still want the upgrades before switching insides and faceplate. I don't see a big difference when I'm in BP mode o disc 9.0 or 9.1. Was expecting things to be quiet. It still gets what seems to be ground interference, no target I.D. Running 0 disc a iron signal would still give a target info right? Thanks Tom
 
This was posted by someone in the know. Gives an idea of what to expect. Hope this helps.
* 9.0 mode slightly deeper than 9.1 mode. It appears that 9.0 mode is approx. 80% DST.......... and 9.1 mode is 100% DST.
* Overall........ this unit is 85% more EMI stable....... at a cost of 5% less (overall) depth. There are certain areas where a standard F75 is in EMI shutdown........ and the 'quiet' F75 can still keep you in the game.
* FA mode is extremely fast....... yet; at a cost of nearly 50% depth loss; but, keep in mind......... it is intended for carpets of nails whereby..... depth is severely inhibited to begin with.
* 'ln' mode is fatigue-free...... and fun...... in heavy-volume iron areas. This particular unit is starting to catch up to the GMP/Deus platform.

Dont forget this unit that Tom tested may be a PROTOTYPE
 
It was a prototype but I understand it this is the one that was put into production. From all the reviews I'm seeing this is about right. I'm waiting on mine and I feel like a kid at Christmas. I have my ET to use but both have a niche where I can use both of them at different sites.
 
Have you tried your frequency shift?

I posted the set up routine before.....

You turn it on in the normal non-DST mode, set it up like you are going to hunt (disc, sens, tones, process) and then if you are still picking up too much chatter, you do a freq shift and see if it will quieten down that way. Often times a freq shift will help.

If the frequency shift didn't help, then you turn it off, put it in DST mode and repeat the set up, including a frequency shift if required.

At this point if you are not quiet or not quiet enough, then you lower your sensitivity or make other adjustments.

The majority of places I can run BP at 99 (always run FA at 99), but I still have the occasional site where I have to turn it down to 80ish to quieten it down, even with DST activated and a frequency shift.

Have tried the frequency shift, I was hoping it would run quiet running wide open. I'm trying to trade the machine right now, I'm more of a coin hunter and it's still not for me the way I hunt. Thanks for all the feedback

I am curious.
Why do you say you need to run at 99 sensitivity to hunt coins?
That does not make much sense.
These things are so powerful yo can find coins 6" down at a power level of 10?
 
I just like maxing power so I don't miss any deep coins and was hoping this would be quiet after the upgrades, could still be the ground I hunt.
 
Deepest coin I ever found before the upgrade was the length of my garret pin pointer. About 9" to 10". And that was at a sensitivity power level of 60.
With the upgrade I found a watch band last Sunday at 12 to 14" at the default power of 80.
How deep are you expecting to dig?
 
Called fisher and they told i should not expect this detector with upgrades to be quiet when running BP mode, sens-99, o disc in either 9.0 or 9.1 and was told it was checked before shipping back to me. After hearing what alot of people where saying about it being quiet after upgrades i was hoping for quiet at max settings. Still like my E-trac over the F75.
 
My Safari and E Trac have always been my go to for coin hunting. I have never been able to run them wide open at 30. Become unstable. Out of the dozen MDs I've had only 2 would go to max and remain stable and they were lower price and not that deep. I don't expect to be able to run my upgrade Ltd at 99. Maybe in one tone and the 5' coil. I could get in the 80's and seem stable with that setup before upgrade. Just my soil in the Piedmont of the Carolina's. Seems like it is working fine to me.
