Need help with new ACE 250

[treasure 06]

Just got my new ACE 250 delivered today but haven't been outside to try it out yet. Did conduct a bench test though, to see how it responds and identifies various targets. Just as I expected, it seemed to have trouble indentifying the difference between pennies and dimes. I know that this is not unusual with most target I.D. detectors, as I have similar troubles with my older White's Spectrum. At least with my White's I am able to tell the difference between pennies and dimes (most of the time) by looking at the target number that appears on the screen, for me dimes usually read between 78 and 82, pennies less than 78. But the White's gets fooled sometimes and pennies are found above 78 and dimes found under 78. I have used the White's Spectrum for so long that I can usually tell the difference between dimes and pennies by a slightly different tone also. Anyway, what I am getting at is, does anyone using the ACE 250 have any tips on telling the difference between penny and dime signals? I do most of my hunting for modern clad coinage, so obviously I don't want to dig pennies if I can help it. Thanks for any help.

This is what goes wrong when manufactures put screens on the detectors that tell the probable identity of a target. Due to the difference in coin orientation in the ground, soil matrix, and other various things, there is no one set of rules that makes one coin id from a different one with any accuracy. By not digging a what you think is a penny, could be a key date dime or even something else like a gold coin or ring. Worth more than many, many dimes. We either nit pick or just have some fun and retrieve the penny and be suprised when it isn't.

Sorry this doesn't answer your question, but there is no answer that works in my book.

To dig or not to dig. I have the same problem with my ACE 250 except with pennies. If the ID says its a penney it usually is. With the dime however, it can be a penny or it can be a dime. Another thing I notice is that whenI get a target it may "blip" back and forth between penny, dime, nickel and back to penny. I dig it anyway. Sometimes It's junk but many times it IS a penny. I don't look at the visual display as much as I did when I first got the Ace. I'll say this however, the ACE has been real good on hitting quarters, even though it doesn't READ .25 cents. It too jumps back and forth from .10 to .10 to to the low end and back to the high end again. I can usually tell now when I have a quarter. I was going to sell my ACE but I'll probably kep it just to have a back up. I'm leaning heavy toward the F4 come income tax return time. For the really deep stuff and hunting around houses , I use my MXT.

I'll share this much.......in the first few months, the machine was almost never wrong on dimes and pennies......from one day to the other, I wrote a post here titled something like "My Ace 250 has lost its vision" because it began to pick up pennies on dime. Never the other way around though. The only difference I've noted is that you kind of know it's a penny when the signal is wider, or you're looking all over the hole for the "Dime" because for one reason or the other, pennies seem to have the worst PP results. They give off a pretty wide signal.

Interesting. Something I have noticed is that when I have a quarter in the ground, the VID doesn't show it as an .25 cent piece. It jumps from .10 to .01 to way over to iron and back to .01 then to .10. It never goes to .25 and stay there. Also, althose little blips that is suppose to indicate I have junk?Well, sorry but some of those blips are NOT junk but coins.
Many times it appears the coin is standing up on end and maybe that is the cause of all those blips. I just don't know. I'm hopeing that the F4 will be better at VID than the Ace250 is.

Also I just heard that there is an F2 coming out probably in 2008 that is a scaled nown version of the F4 and is supposed to be a real Ace killer. We'll see. I'm already dead set on getting the F4 next year.

I go by tone and it is almost always right not on my 250 on my minelab...and what is a...F2...&...F4 ?

I`v learned that i can discriminate against the penny to avoid digging zinc trash and still pick them up under the dime range.

As far as dime and quarter ID, its right on as long as i have penny's undiscriminated.

My first cheapo detector took me 6 years to learn and this one is just peaking my interest with it`s flipping back and forth between ferrous and non ferrous metals.

I`m just beginning to learn which to ignore.

By the way I`ve picked up some interesting items that registered as 50cents but looked nothing like a coin but fun to try to ID.

I have that problem too with the Ace. I think I figured it out 1 day. I kept getting dime signals and most were pennys. I started looking at the dates and they were made before 1982. Pennys before 82 were almost all copper. Now of course they are zinc. I dont know if that makes a difference but check your dates when you get a dime sig and pull out a penny. TMAN...

I have the ace and I dig all, discriminate all iron! I don't use the display for target ID, only for pinpointing and depth.

The Id is always wrong.
