Well folks, I'll say this one more time just so that someone else can know..
My electronics engineering experience, and my education and R&D in metal detecting engineering and my experience as an electronics mechanic and electronics technician, plus my experience in repairing and using enormous numbers of detectors, many of which most people on here have never even heard of, plus my side-by-side experiences comparing the aforementioned detectors against the Aces has clearly shown me that the F-2, Silver Umax, Compadre, and White's low end detectors are decidedly superior to the Aces of all varieties. The Aces (again) use circuitry that is at least 20 years old, and that's (partly) why it is inferior and a dinosaur compared to the more modern circuitry currently used in the Tesoros and Fishers detectors that I mentioned above..
As I said above, the Aces are fine for someone who really hasn't used any other detectors because they would not know the differences between them anyway, would they? If they really did, they would never make statements saying that the Ace was superior because the real world proves the facts and the impossibilities..
Now let's get back out of the dream Alice, and we'll rescue the dog too. The Aces do not have the ability or the power or the more complex current circuitry to enable them to beat the cheaper Tesoros or Fisher currently made, and as most of you already know, I have no opinions, I only state facts, nothing more. Maybe that's because of my precision work in life and maybe it's because of my candor and not wanting to BS anybody about anything, but the truth is, that in the hands of an experienced detectorist, the Aces are inferior to the other mentioned detectors, case closed.
