This pic indicates how hot the 250 is in all metal..

This tiny wire was recovered from over five inches down. The 250 barked loud and clear on it in all metal.

Once thing thaw out here, I'm going to give the All Metal, All The Time method a good shot with my Ace 250. Lots of folks recently have been touting that more depth is achieved this way.

The more I research other detectors, the more satisfied I am with the Little Feller.

:crylol::garrett::clapping:
 
Dunno...I still disagree as far as the all-metal vs
notched modes using the ace machines. I really don't
think there is any difference. The machine is always
in all metal mode as far as I can see. There should be
no depth lost in coin mode, if a coin is the target.
I've never been able to tell any difference air testing.
I often hunt in all metal mode, but not to get any
extra depth. It's just to avoid missing some weird
object I might want to find.
I'd be interested to hear what Garrett has to say about
the ace all metal vs notched modes. With the new technology
notching they use on the ace, I firmly believe there is
no difference. All the notches do is turn off that particular
notch tone. Nothing else. They don't stunt the machine due to
filtering, notch, etc like some of the older machines.
Course, if I'm proven wrong, I'll be the first to admit it.
I sure don't see it here though. It would be interesting to
hear Garretts view on this.

i agree with nm on this. if i am in the coin mode certian items that are notched out are still lighting up on the screen of the ace250. the detector is still detecting those hits. just the tones are notched out. i think the ace250 is in the same allmetal mode all the time.
 
I believe on notch machines there is no loss of depth as in some of the progressive disc machines. But by running a lower disc like relic or AM you will learn more about a target.
Try this test. Take a copper cent,dime (high coin) and hold a medium size nail on the coin. Swing over your coil in the "coin mode" what do you hear? Depending on how the nail is positioned you may hear a coin beep every 3rd pass, maybe every other pass? You might think it's one of those false signals you seem to be getting when your out in the field.... Maybe if you heard that sound you may not dig it?
Now holding the coin and nail the same but this time in relic or AM mode. Swing the coin over the coil now. What do you hear? You hear a low tone and high tone probably? Now you have just heard your detector tell you that you may have a coin next to some iron. Now you have more info to dig or not. So by running a low discriminate setting you will be digging more iffy targets that turn out to be good ones.
I admit if I only have like 30 minutes to hit a site I will run in the coin mode first. Then each time I go back to the same site I will lower the disc as time permits. This way you will eventually retrieve most of the targets.
 
mine definately reads diff when im in the coin mode. Thats why i asked the other day if it looks for a circular object in coin mode. I can get hits in all metal mode that say foil or something, then go into coin mode and it might show dime or penny. It'll usually be a round flattened wad of foil. I've seen mine do this several times, still seems to me like its looking for the size, roundness of a coin in coin mode, I may be wrong. But mine definately reacts to the same object differently in diff modes. I may be crazy lol, but it sure seems like it to me. I'm still a rookie though and may not know what I'm talkin about, it may just be my immagination.
 
That is a good observation. I am paranoid I am going to miss something. If there isn't much trash, I will run it in AM. I am 100% AM on the beach. To make the Ace run quieter, I run my Ace mostly in jewelry mode. I like hearing all the tones and I make the decision to dig. I have gotten some good things that way.
 
It reacts by the conductivity of the metal. It's not looking for the shape but the shape has a lot to do with it's signal.
 
I know you guys are aware of this already, but remember that the only "true" all-metal mode on the Ace is when it is running in pinpoint mode. It is then a true all-metal non-motion VLF.
It was said that the pre-programmed modes including the "all-Metal" above the jewelry program are just notching out audible responses. This is correct.
When NOT running in pinpoint there is depth loss because of filters being used. Go ahead and try and air test running "all-Metal" program vs pinpoint and I am sure you'll be suprised.
THIS is why Khouse's pinpoint trigger mod is sooo cool.
Now if the Ace just had a threshold adjustment to change the shift on that tone!...sometimes it's difficult to get a sustainable threshold tone in pinpoint on the Ace. Moisture and mineralization affect it sooo much. Sometimes it'll hold a tone in pinpoint for only a couple swings and then you have to release and depress again to get another decent tone.
I have dug MANY deep targets that my Ace would not even ding ONCE in normal hunting in the "all-metal" "program",...and then in pinpoint it is CLEAR that a target is there. Dig down...viola!...nice old deep coin.
 
I agree. I often do run all metal, just to hear
everything it hits on. But like you, if I was at
a place the first time, and a lot of trash, I might
notch it down.
Guess depends if I'm looking for just coins, or anything
in particular.
I'm fixing to excercise the machine a bit tommorow.
I bought ten acres of land a couple of weeks ago in
northern Hughes county Oklahoma.
I'm leaving tonight to go up there and prowl around,
check things out, etc.. The property has a creek that
runs across the west side. I'll be prowling around
seeing if I get any hits on anything pretty much every
where I walk. In this case, I'll probably be in all
metal just to make sure I don't pass up some old iron.
I'm also hoping maybe I'll find some arrowheads some day
around there around that creekbed. The land is pretty
much hardwood forest, and no one has ever lived there
that I know of. So it will be interesting to detect
"unused" land.. If I find anything, it will probably
be old shotgun shells from hunters... :/
I'm gonna leave about 10-11 PM, drive all night, and get
there about 6 AM or so.. Stay there about 24 hours and
drive back to Houston. It's about a 900 mile round trip.

Danimal,
You are absolutly spot on. I can't wait to see what the new version of the 250 will be! Maybe it will be called the 250Z?
 
Bill,
Great example! The 250 seems to have plenty of power and even the stock coil is sensitive. How did Charles do it?
 
Sorry Willy but I beg to differ. I have found MANY targets while listening to the threshold shift while hunting with pinpoint depressed that the ACE doesn't even make a peep on running in normal mode...regardless of sens. setting.
Please not I am NOT talking about locating a target first, going to pinpoint and then while already over the target depressing pinpoint again (detuning) which shrinks the field size to allow finer pinpointing.
I am talking about actually swinging the coil looking for object with a full field size present. If you do it right you can hear the threshold tone increase.
 
.....Almost every time I think about purchasing another, more expensive detector, along comes a thread like this one, talking me out of it.

From what I read here, by searching in pinpoint mode, what I've got is a $200 detector with a VCO Prospecting Mode.


COOL
:crazy:
 
Dick,
I am not sure if the Ace uses true voltage controlled ocillation in pinpoint but it probably is.
If the Ace had manual GB and adj. threshold level you could really crank it up regradless of soil conditions. As it is, hunting in pinpoint can be hit or miss as it just won't hold a decent tone sometimes. When it does, it will be GREAT to have the trigger mod done! Like I said, I am AMAZED that the panel-mounted pinpoint switch hasn't failed yet. Another testament to Garrett's componenet and build quality.
I myself am in the market for a top line machine and right now. The Ace will still no doubt be an important tool in the future still.
 
The Ace is not a non motion VCO unit. I wish I knew what Garrett was coming up with next for the 250?
