AT PRO doesn't have all metal mode. Has zero mode

Info from talking to Garrett Customer Service Rep:
The AT Pro has several search modes with various options. NONE of them are a true all metal mode, but there will be a "zero" mode.

While the AT will run at 15 Khz, it will NOT be using the 15khz groundhog circuit from the Scorpion Gold Stinger, which will continue to be manufactured.

SO, the AT Pro is NOT an update of the Scorpion.

It will be interesting to see how it does for prospecting without the all metal mode!!???
 
Old news....:goodnight:
 
I understand 0 mode and all metal are the same.
I could have gotten the info wrong so you might call Garrett
and check this out, or maybe someone here can confirm.

It wouldn't be a factor at all in my purchasing one...
Though it's odd they left it out.
 
But it does have the AT Tone roll and expanded iron to help compensate and help ID the iron sounds.

True non-motion all metal is when you can hold the coil over a target motionless and still get a normal signal.

Garret says the zero mode is not true all metal. You can turn up the DISC on it.

Remember, ATP is silencio search, sans threshold. Lesser responses could be blanked out and lost entirely.
 
The Garrett Scorpion Gold Stinger manual describes how a threshold-based all metal mode can find deposits of gold dust by listening for a rise and then a decline in the threshold tone. Silent Search detectors like the AT Pro may not be able to achieve this, unless they display a visual ground mineralization number. The rise and fall of the number value could do the same thing.
Andy Sabisch, reviewing the Scorpion in Lost Treasure Magazine, found a gold deposit by listening to the threshold tone. So the Scorpion may outperform the AT Pro for prospecting. We'll see, when the Pro is released. How about a Scorpion update?
 
Hi Zadok,

Yes is true the Scorpion will do that and also the GTI 2500 can also find those deposits with its all metal mode. I hear a Scorpion update is underway, but just rumors. Hard to beat an all metal mode for prospecting. But I know my Ace 250 will pick up a .1 gram piece of gold in air. But in hot ground is does not. I suspect the AT PRO will do the same but will be better in the hot dirt, so likely will do better on the little nuggy's.

While Garrett customer service claims that the zero mode is not a true all metal mode because it has discrimination, some people feel that this "sounds like" an all metal mode with discrimination but no threshold. A Garrett engineer or the manual of the new AT Pro could settle this. The AT Pro has 5 OTHER search modes, each with different options. In PRO MODE, you can adjust tone and audio, among other things. The STANDARD MODE is for new users.
 
Its already settled..the ZERO mode is the same as the ZERO mode on the GTI 2500. It has a preset ground balance and is a discrimination circuit. Its ZERO because it detects "all metals" until the user notches out a certain type of metal......its still a discrimination circuit pre-set with no metals notched out, not an All Metal Mode W Threshold Circuit which nothing can be notched out.

Good description of zero mode, Bearkat. I don't like a preset ground balance! Field tests can evaluate the all metal mode on the pending Scorpion update with the zero mode on the AT Pro. Since both detectors run at 15 Khz, it would be fair.
 
Are any of these replies from detector dealers? They could test the motion discrimination zero mode vs. the threshold-based non-motion all-metal-mode on the pending "Scorpion II" update in their test gardens. IN Theory, non-motion all-metal is supposed to go deeper.

If the zero mode on the AT Pro has a preset ground balance, as Bearkat has stated above, it would be a nightmare in heavy mineralized ground! But the ATP has 5 other modes, none of which are non-motion all-metal, however.

With no threshold based non motion all metal mode, I don't think the waterproof AT Pro can match the pending Scorpion update for prospecting. The Scorpion will go deeper and perform better in "hot", mineralized soil. The AT Pro is not really for prospecting!
 
I do believe that is my dealer in the light blue shirt standing to the side... Keith Cochran of Bonnie Blue Detectors. I had not seen that, thanks.

Dude you just dont understand sometimes. The AT Pro has a pre-set ground balance on the whole machine...PLUS an auto ground balance circuit with addtional manual adjustmant. It will work VERY WELL in hot ground. The pending Scorpion "update" has no time frame as Garrett has not released anything about it and it is a rumor anyway as I said before.

Garrett says it will be a good prospecting machine then I'm sure it will be good, not the best, but good.

The Pro mode is the mode you would want to prospect in on the AT PRO.

The entire AT Pro detector is a discriminator machine with Pro mode that resembles an all metal mode with some high tech software and audio functions.

From what I have seen so far the AT PRO WILL go deeper than the Scorpion with the new large coil and new technology on nuggets greater than .4-.5 grams. Maybe smaller.

I will find out, soon enough!

P.S. The Whites GMZ gold machine has NO THRESHOLD either, it is a silent search all metal machine. What you say about that? :poke:
 
You should work for Garrett Customer service. They didn't tell me all that when I asked about the pro mode. It's time to await the debut of both detectors and read the field tests.
