F75 depth reading

Is anyone else find that there pinpoint depth reading to be all over the place? I've played with my new F75 (the first one was doa right from the box!!) for a few days now and the depth readings in pinpoint are only correct or even close to correct a handfull of times in the hundred or more targets I've dug.. Doesn't matter what the depth of the coin is it reads 4" on meter and one would be 1" and another would be 6".. Even deeper targets aren't close to the reading the machine is giving me... This includes coins both shallow and deep..
Very disappointed in a thousand dollar machine that can't even get it close!! My other detector is almost always right on the money to a inch or so that only cost half as much!! So I know that sooner or later I'll end up destroying a good find because of its inaccuracy.. VDI is always jumping and doesn't lock on a number alway even a good one always varies at least 3 numbers in the VDI range.. Is this right? Seems shoddy even on a strong shallow target!! I've been through all the programs, sense high, middle ,low, discrim everywhere, and no accuracy at all!! And machine that half its price will outperform it every time in VDI and depth reading in pinpointing!! Depth seems to be great but all I've dug a depth is trash but I'm sure coins will come.. Falseing doesn't seem to bad so I'm cool with that also.. GB in allmetal motion and first then I turn on the discrimination (If any).. Is there some trick to the pinpoint depth and solid VDI or did I get another bum machine?
 
No matter what it was, or how deep 2,3,4,5,6,7,8 it read 5...
 
Yeah, the F75 I have is going back and a new one is on its way (for a variety of reasons). I was getting a constant reading of 7 inches on a 4-inch target and it was always off on the depth. What I don't get is their policy of just replacing the machine instead of taking it back and fixing what's wrong with it. I'm almost dreading getting another machine, because I'm afraid I'll just wind up with a different set of problems. I'm willing to be patient in the hopes that I can wind up with a machine that will see a little deeper than my MXT and have more capability to sort out good targets from bad, but if what I'm hearing is any indication I'll eventually get fed up with this mass marketing and find some other approach. Time will tell.
 
If the depth reading is the same on every target, regardless of the targets depth, that would be a problem. (IMO) I have one of the earlier F75's and mine has always read deeper targets a little deeper then they actually are. I personally don't have a problem with that as I can now pretty well tell the depth of a target by its tone. As for bouncy vdi readings, inaccurate pinpointing and or, nearby targets can be a cause. Usually, though, trash targets nearby a coin target will bounce more then 3 numbers. On trashy sites, one has to pinpoint precisely to get a lock on. Good luck and HH jim tn
 
It's more stable, deeper, and hits very deep... I think it's just a matter of their getting a handle on tweaking all together for optimum operation....
Not many companies will send you a new one..Take it and be glad...You may just be amazed at the results..
 
Good luck!! My first was trash out of the box !! Menu button didn't work.. This is the second one and I've been through all the settings as I said before.. But they couldn't get something as simple as the depth reading correct!! On their best.. What the heck is up with this!! Pinpointing isn't a problem, but a depth reading that not even close, and it's all over the place so it can't be compensated for, come on now..What are we suppose to do keep sending them back until we get one that works!!! I was always a fan of fisher even bountyhunter but this is a farce!! It will be a great detector if it ever works!! So should I send it in, in hopes of getting a good one or get rid of it..
 
Contact Fisher..or Mr. Mike Scott..Fisher will send you a call tag..List all that's wrong and they will reset all calibrations, or if they can not fix it will send you a new corrected machine.. Remember coin depth on coin size objects are only a guess at best when the machine you are using sees so much under the coil as the F75 does.. If you slow it down isolate your target under the mid point, or just a little in front of coil connection to rod..the depth meter will be more accurate.. On the small coil, on any machine..Whites, Tesoro, it will be off.It is calibrated to the standard coil..It is my understanding that even though Minelab computer recognises their different size coils on the Xterra series the depth is off a little on small coils.
Most companies calibrate to the standard coil.........
 
Using the stock coil.. Haven't even tried the small one yet.. I know that its a suggestion but even my other machine, when switching coil size, the depth reading will be off a constant amount so I can compensate for it..
 
Great..it's truly an awsome machine..
 
Well, got my second one and at least now I have a machine that works a lot more like advertised. The only thing still off is the depth reading, but I guess I can live with that and find a way to make it work. Interesting thing is that the coil plug fit better into the jack on the back of the processor and this seems to make a huge difference as on the first machine it was only by putting on the inline pinpointer, which also had a plug that fit better, that I could get the first machine to settle down. But, the power capability was still not up to snuff on the old machine and the new machine is clearly more powerful without going unstable so easily. I wonder where Fisher is mass producing these machines out of, because they really need to look at their quality control. I for one, would like to see a continuous improvement in their offerings. Good thing these things have a 5 year warranty because the relic hunters (myself included) are liable to need it. Funny how Whites only has two years on there machines and they're built like tanks, for the most part.

Anyway, I'm jazzed to get started using this machine. Should be a lot of fun hunting the pounded parks in Huntsville.
 
Well I sent my F75 in after a call and talking to Mike Scott.. Picked up on July 21 and received it today!! It seems it had a bad coil.. If it ever cools off and the humidity goes down some I'll give it a good workout..Even with the bad coil I did like the super fast response of it and grabbed a silver rosie a couple inches away from a tab.. If this machine will do whats advertised it will be a giant step forward...
Thanks Mike!! (and A big thankyou Richard for all the help so far!)
I'll let you know after a good long shakedown hunt..

I'm not impressed in the least, but I'm going to try it one more time.. But so far it doesn't look good..
 
Took it out for a couple of hours and I'm not happy.. I'm going to try it again but unstable and erratic pretty much in every mode and sensitivity except the all metal motion(I do like that mode) to the point almost useless.. Vdi more stable then it was but id's pennies as dimes and so forth..Pinpoint depth is all over and only accurate or close a few time in the 30 or so targets.. Thought it might be the high gain, low gain in the disc. mode so I went up by 5's and its barely usable.. First Texas said it's as it should be.. Guess maybe I'm not experienced enough to run it since I've only been detecting since the early 70's with all brands high, middle and low end and both vlf and pi's.. I usually run no disc. on my detectors...Had my son follow me with my other detector and scan the same targets.. Half the price and it ran great, smooth, vdi accurate and depth reading in pinpoint was as always close..(Had it shut off until used just in case it interfered) Ran circles around the f75.. As far as depth goes wasn't anything to brag about.. Soil is mild here about 60-61 gb and fe usually at 0.. I'm gonna give it one more shot.. I was contemplating the F70 but now I'm not to sure about it since I'm having all this trouble.. I have no brand loyalty just tell it like it is ..Anyone who knows me on the forums also knows I'm a straight shooter..
 
I just spent a solid hour and a half air testing with a quarter..I usually test with a dime..Every mode, de,je, pf, bc every sensitivity from 99 down in increments of 5..Every disc. level from 0 up to 65 by 5's.. Gb from 0 to 50, 60, 70, 80, 90 and 99 set in the all metal mode.. Best in discriminate mode was 8" barely 9"( broken signal) (that's from 0 and up to 65 by 5's) in all disc. modes.. All metal both static and motion (same sensitivity test as discriminate mode) from 0 up to 99 same with gb.. Best was static 10"+ a bit but I'm being kind.... Motion 9".. The bad coil air tested better!! Wheres all this depth claimed at?Do we keep sending them in the hope one will actually work correctly and do what its claimed to do!! I'm beginning to wonder if they just threw another coil on as they seem to have a problem with them and said it's good enough!! Sorry about the rant but I'm PO'ed.. Darn near any machine will do this and be stable and more accurate..THIS BITES!!!
 
maybe ya got a bad one!..tell'em about it and send it in!..let 'em fix it!..got a 5 year warranty!

(h.h!)
j.t.
 
The first one was doa right from the box!! This is the second one and I had to send it in and they said it had a bad coil.. How many times do I have to do that to get one that actually works?
 
must have got monday mornings production offerings!..everybody's "hung" over on that day!....yeah!..i hear ya'!..it sucks to be sure!

(h.h!)
j.t.
 
I think they must of been still drunk!!! I went out for a bit to try again still the same and guess what when I was bring it in I noticed a wobble,, The battery box is loose!! I'm done!!! If you use disc it only as deep as any other detector.. Vdi unstable at all sensitivity and modes!! No one gets the depth advertised and in the manual.. I would like to put here what I really think but I don't want to get banned!! First Texas arre you reading this You should offer a full refund to the people you took with this terrible product!!! YOU SHOULD BE ASHAMED!!!
 
Well I'm sorry to waste all of you good folks time... I'm done and it's gone..
