Yes, I totally agree. If I had one of the early units, and had quality problems that prevented the unit from maintaining stability, I'd be pissed if I had to ship it back to the factory (at my cost) and pay them to fix it (their design problem) and pay for the shipping back. I understand that nearly all the early stability issues were caused by poorly sealed coils.
I purchased my F-75 used after it was sent back to the factory for a "re-furbishment" by the original owner. By that time Fisher suspended the practice of charging customers and did the work for free. In fact, they changed out the coil, the display and the battery holder. Other than the rods, the unit was returned brand new.
Still, the Fisher can be easily setup to be non-stable. There is so much potential gain in the circuitry that if the user is not careful, he/she can put the detector in an unstable condition. But once some experience is gained with the F-75, it's easy to dial in a deep, stable setting.
Here are some of my thoughts about the F-75. It can be very unstable at times, but most of the time, it's caused by the operator setting different settings. The F-75 remembers everything and because of this can become very unstable. I was out hunting the other day with my F-75 and as soon as I turned it on, it was making all kinds of noises. I turned it off, pushed the trigger forward and pushed the red button at the same time I turned the detector back on. That fixed all the noise. I hunted around 3 hours with no problems. People must reset their detectors from time to time.
Also while hunting in really hot soil, I always run my detector in all metal. It must be ground balanced constantly. All detectors that hunt in hot soil should be able to be ground balanced. If not your going to miss a lot of good targets. In Virginia, in very hot, hot soil, in all metal, it's best to dig every target. If your not digging square nails, most of the time, your not digging bullets or buttons.
As an older guy, 62, I like the F-75 because it is light weight. I have 7 other detectors and this is my choice detector for the hot Virginia soil. I also use a SunRay probe on it.
I saw lots of SE's in Virginia being used with much success, but my F-75 was finding just as much as they were.
Just some of my thoughts. Good Luck with whatever detector you choose.
