[size=large]Golden UMax Q & A[/size]
Q. Will the Golden hit a dime at 7" with a clear high tone?
A. My Golden UMax will air test that on a clad dime - with the high tone intact.
SENS: half way into the boost zone
THRESH: barely audible
NOTCH: OFF
DISC: Preset
a). Fluorescent lights on in the room,
b) Audio results from the speaker alone, no headphones...
Keep in mind, this is an arbitrary test - 7" represents nothing in particular. This was an air test, and is pushing the SENS. But, it is also without the THRESHOLD punch of super tuning and I'll add it was very stable even with the lights in the room. .
I would expect the high tone to drop a notch after the 6" mark. But, under most conditions, anything that responds clearly in both swing directions and indicates over 4" deep should be recovered - period.
Q. What about adding a manual ground balance?
A. As for modding the detector with a manual GB, I have not done it. It voids the warranty and I live in South Carolina - the soil here is universally mild. Only on rare occasions have I seen problems, and those I recall can be traced to mineralized gravel fill being present. Whenever I test the preset balance, I find it is slightly positive.
Remember, the Golden uM is a micro max detector. Expecting it to to detect to China is unrealistic.. so is expecting it to be a "do it all" detector..
But within it's limits, it is fast, accurate and light. And when the conditions are right, it can impress.
========================================================================================================================
So you are saying then that the Golden will go every bit as deep as a Vaquero ? ....
No. Under the conditions at that site, i.e., soil, target depth, types of targets, etc., the Vaquero and the Golden were equal. Elsewhere, under different conditions, that may not be so.
But I AM saying that the MicroMax cicruit that the Golden uses is better than you may think, or have been led to believe.
I pulled a quarter from 8-10" last season with the Golden uMax, which gave a clear high coin tone.
Would the Vaquero have done that? Probably... but not with tone ID. Remember there are no One-Size-Fits-All detectors.
You mention the Vaquero being an "iron hog" .....Can't the Iron be discriminated out as the first item on the dial? ....
That's the theory, yes. In practice, it is generally only like that with smaller iron, say small nails and so on. Large iron items, well rusted in the soil may actually overload the circuits and cause some detectors to respond to it. Discrimination only sometimes acts like the TV commercials suggest it does, separating "trash from treasure..."
Now, some "Tesoroists" will say they can tell iron by the short clipped response or "bad sounding" audio it gives.
But does that help a newcomer, who may not have a trained ear? This is why I like the Golden - it has tone ID.

The Golden Depth
If you like the Silver uMax, then you know what the Golden will do in terms of depth. It is the same MicroMax circuit, same front-end performance. I've always been tickled at the folks who will trip over themselves to get a Silver-series detector - but turn their noses up at the Golden uMax because someone says it lacks depth. I've owned them all, and there is little difference in that regard. Here's a true story from last year....
I used a Golden uMax beside a Vaquero in a series of early spring plowed field hunts, on the same piece of land. This gave consistent test conditions in the field. Guess what I discovered? There was nothing the Vaquero could find that was beyond the Golden uMax. And the Golden gave me a sweet, reliable iron tone ID in low discrimination settings - something the Vaquero could never do!
Tones Rule
The iron and high tones are very distinct. There is no mistaking them, so there is little worry there and we can close the book on them for the moment.
Inevitably, complaints about the Goldens' tones center around those which define the midrange of conductivity.
They are indeed close together, i.e., the mid-lo ( foil / nickel) and mid-high (tab / zinc) audio tones are not widely spaced in frequency.
And as odd as that seems, it is for a reason: the Golden uMax is a mid range detector. It is most expansive, having it's greatest resolution in the mid range. SO just what does this mean?
Well, I can ID most common types of pull tabs with it, for example, just by working the controls. With practice and precise NOTCH control adjustments, I can also isolate a nickle from those nasty pulltabs that are just a teensy bit above the nickel mark. These are the same ones that usually usually fool other detectors.
I can do the same for the foil end just below nickles.
MAKE NO MISTAKE - this is a very fine bit of discrimination work, and is done without digital filtering or enhancements.
Somewhere in my files I have a "pull tab map" that shows umpteen types of pulls and where they fall on the Golden's NOTCH control.
The Trash Has it
Those people who swear by the Golden uMax do so because of gold jewelry. Iron is easy, as is clad and silver coinage.
But, it is a cruel truth of the Universe that the material thing we value above most others - gold - also reacts just like all the junk we detest.
Since alloyed gold can ID as trash, anywhere between foil and pennies, you have no choice but to recover the targets that signal cleanly in that range. With that said, what is the compelling importance of very distinct mid range tones, when you must recover all targets in that range, anyway, if you are to get the gold?
After a bit of use, the tones WILL come through clearly. Nickels will "sing" to you if you listen.
It does present a kind of "squawky," even abrupt response suite, though. And there are really SIX distinct tones. Also, trash or good targets mixed with trash will offer a tonal crossover, forcing you to pay close attention.
So the Golden uMax can be a noisome challenge to those who expect a detector to tell them what they've found, instead of recovering what it finds. It isnt really for the casual detectorist, although the paradox is that is the best way to treat it. Let it signal to you, listen closely and recover what it finds. Do that for awhile and youll get the hang of what Mike Hillis has called one of the best "cruiser" detectors made.
