Not all that glitters is gold. My unit was a new out of the box unit...not one that was sent in for upgrade. The software number on mine is 11-11-14. I will be adding my own video to YouTube over the next few days when I can get some decent internet connection. But mine tests almost identical to the one here. Looks like a major difference to me between units.

Keith's detector looks like an exception right now, not the norm. Don't buy one or upgrade and think you're getting one like it. Maybe you will maybe you won't. Fisher didn't have their ducks in a row with this release, similar to the release of the F19. Right now isn't the time to buy.

I don't think First Texas has an issue with the detectors so much as they have an issue with quality control. How can units get out the door with such a disparity of results? The excuse used to be analog units with a zillion things that need calibration. These things should stamp out identical yet they do not. Are there numerous on the fly software changes occurring? If that is the case, why not wait a bit on the upgrade program at least. There was no rush to market to do that. I don't get it.

QA issues equals non-ftp/american factory made boards from south of the border. Also reasons for launch delays
The most disturbing thing about the rollout, at least to me, is that it looks like a reviewer just got a smoking-hot one, and average purchasers seem to have gotten somewhat weaker ones. Total coincidence and luck of the draw? Possibly, but it still looks bad even if it is pure coincidence. I hope everyone who just dropped a thousand bucks of hard earned money on one of these eventually gets a hot one.

This video only shows air tests. The previous videos had coins laying on the ground. Personally I think about the only thing air tests are good for is checking target VDIs, tones, etc. I don't think I would put much weight in air tests when it comes to depth. The ground balancing can play tricks in air tests. How is your unit performing in the field?

I have 14 years of manufacturing experience and a great deal of it in quality control. Where I work at, we have a baseline and spec window that our parts must meet. If not, they are scrapped. When air testing detectors against different models, I can understand why that data may be skewed. When comparing detectors of the same model with the same settings and test objects, you get a pretty good picture of the base line for detection distance. Depth is determined by in ground performance which is hindered by ground balance settings and the overall masking effects of the ground itself. I think each detector of the same make and model should perform similar from one to the other in a controlled test environment. When they do not, such has been pointed out in the videos and forum posts, then something is wrong. Keith ' s detector in the video is above anything I've seen so far. At least one other forum member says his new F75 mirrors Keiths. Mine happens to mirror "detectingMO" and his test at the same settings. So my question is...what is the base line for performance? I want mine to be like Keiths. We're not talking a half inch or so difference. We're talking almost 6 inches different. That's a big difference!! His test video in highly mineralised ground is better than mine can do in the air. I don't expect to retain the distance in ground that I can get in the air. But I certainly expect machines to be relatively equal in today's manufacturing world. And this is showing quite a difference.
If you bought a car for gas mileage. ..say you bought a car rated for 50 MPG. The auto magazine tests gave it big ratings and reviews and claimed getting very close to that 50 MPG in thrir tests. Say they got 46 to 48 on average. So you buy one and only got 20 mpg. You probably wouldn't like that too much. Especially if some folks tried telling you that 20 was good enough. That's about how I feel right now. We've read all these good reviews and seen the videos from testers and are expecting to get the same or close to what they have when we buy one. Then we get what we got and people are trying to tell us " well that's good enough". Sorry. Ain't for me. I'm calling Fisher Monday morning and they better hope they don't give me a line about it being good enough.

I am reading all this with interest since I upgraded my unit in November.
I would have to agree the max depth I can see in an air test on my unit would be 12 to 13 but it was indoors and there was some static from EMI. I wonder if ground balance settings or frequency shift would affect results. If so all who air test should use the same settings. New batteries should also be used.
In the field I use discrimination mode and have hunted coins in De and Fa. If I had an iffy tone I changed the setting to Bp and definitely picked up a strong signal. I rarely use All Metal. One reason I purchased the F 75 was the 16" depth.
I think the upgrade for me made the unit feel more surgical like it is better at separating targets or I understand the tones better. Maybe my unit was not working 100% before the upgrade too. Hard to tell. I think the question of depth is worth discussion for sure. If depth is gone what next?
I feel the quality of my finds in the three weeks have improved. A silver barber quarter and yesterday a 1937 wheat at a kids merry go round I cleaned out prior to the upgrade. One way I want to judge the success of the upgrade is to go back to places I hunted prior to see if the new programming can find missed stuff.
So back to more testing today and hopefully more and better discoveries.
I am going to get 4 Lithium AA bats. Find a quiet setting and do some air testing at 65 Ground balance (my average here) and maybe compare that to the default settings.

I don't think your unit is "good enough" and I hope you fight to have it made right. A properly functioning F75 is a fine thing to have. I'm hoping I get one myself. If not, I will just use the Nokta instead.
That is the way it works. Fisher either delivers, or people go elsewhere.
