After the AT Pro Upgrade...

Hello fellow metal detectors. I have been following this section of the Findmall forums for quite some time now. I was one of the early purchasers of the AT pro. I was flat amazed at the depth that this baby got BEFORE I sent her in for the upgrade.

I just got my detector back a few days ago. Out in the field, I cannot air test a quarter at farther than 6 inches max. This is with the 8.5x11coil or with the 9x12 coil. I have tested it in different soil conditions as well. Our soil here is pretty hot. Most soil is 90's on my ground balance. I tried resetting the detector to defaults and every other troubleshooting method. Nothing will get any more depth.

I really wish I wouldn't have sent it in at this point. I had a good detector before they did whatever they did to it. I also checked online, and other's have experienced the same problem that I'm having after sending in their AT Pro. What do you folks think? Should I send the detector in again? I was really happy before all this...
 
The only problem I had with the detector before I sent it in was pinpointing deep targets. I told them about this when I sent it in. It also seems that when I sweep the coil over a target since the upgrade, that I don't get as long of a response from the speaker in pro mode or in standard.
 
Thank you for the prompt reply. I'm glad that I bought a good product that Garrett stands by. I will give Sue a call tomorrow morning, and mention I was referred from the Fidmall Forum. Thanks for the help!

Here's some pics of some of the finds when my AT Pro was working properly this summer:
 
Something tells me they are turning the SENSitivity back to try to avoid the falsing issues the older machines had???

HH,
 
I two have been watching the AT Pro forum post. Been thinking about buying a AT Pro for last year but waited until Garrett worked out the bugs.With the new upgrades on the AT Pro I was just about ready to buy one. . Now I'm hearing about new machines not having the depth and machines being sent back for exchange. Also hearing about upgrades effecting the original depth of the machine. Ones again I'll be waiting to buy one of these machines.The two Garretts I have are Good enough. I think your right GoGoGopher they turned the sensitivity down. I sent my 1500 in about 3 years ago for adjustment and got a mineral chip upgrade( or something like that) seems to be a sluggish at this point. So who knows, I still like Garrett detectors.
 
I was thinking about these issues earlier, and I thought that maybe they turned down the sensitivity internally. I'm hoping that they turn the sensitivity all the way up on mine, because falsing was never a problem for me at all.
 
I just called Garrett and had them attach info to my RMA. Since falsing wasn't a problem for me at any point, I asked the woman I spoke with to have them turn the sensitivity back up. I will keep this updated when I get my detector back next week. I'm glad I joined this forum!

:detecting:
 
What was her response when you said turn my sensitivity back up. I never heard anyone request that. Anyway the verdict is out on buying a third detector.Like I said looking at a AT Pro once it has a reputation of its depth like the E-trac if you can believe all that also.
 
She said that she would inform the technician to turn the sensitivity up. From what I understand on that phonecall, I think there is a way to turn the sensitivity up internally on the machine. When I sen't it for the upgrade, I mentioned that I had problems pinpointing deep targets. That was true, but the depth it got was amazing. I wouldn't mind having to dig around a little bit more with all that depth!

In the next week, I will give an update as to how the machine performs since asking them to make the repairs. Garrett invented this machine, so I am sure they are experts at getting it "tuned in" to that sweet spot.

I have read online about other people who have had problems with the Pro, and sent it in to get it fixed, and got it working like a charm. I have read select few other stories about people who have been RMAing their detector multiple times and still having problems. I know how the machine worked when I got it. I think they will fix it and send it back as good as new, it's just a good thing that I remembered to call.
 
Marc - I can't help but wonder why would you picture a clad dime and some sort of flower item that is obviously not silver or gold as examples of the finds made with your super-hot, pre-upgraded AT Pro?

I follow this forum and I haven't noticed others who have sent their machines in reporting a loss of depth after upgrading. I didn't notice any loss of depth on mine after sending it in for an upgrade.

The idea of Garrett turning the sensitivity down internally for upgrades and back up upon request is difficult for me to comprehend. Why they would do this? Marc, what was the lady's name who said that Garrett would internally increase the sensitivity for you?

I'd be interested to hear from other AT Pro users who have been on this forum for more than a couple days. Have any other AT owners noticed a loss of depth after getting the upgrade?
 
Marcomo,
It's obvious he is new to the detecting thing! Cut the newbie some slack. He will figure things out with time. I doubt Garrett would turn down the sensitivity on their detectors also! Must be an operator erea or mistake on the repair technician's part? Marc-Montana nice finds there everybody has to start somewhere! Keep us updated as to how you make out?

Bandit - Marc said he was one of the early purchasers of the AT Pro, so that means he's had a good six months with it anyway. Marc is new to this forum, but he certainly is not an AT Pro newbie.

Marc's posts seem to have a "damning with faint praise" feel to me. He raves about the amazing depth of his AT Pro...the old never upgraded one. The one you can't buy anymore.

So why would anyone contemplating purchasing a AT Pro buy one when:

Units being sent in for factory upgrades are being made worse...

Garrett turns the sensitivity down lower on upgraded units...

It has trouble pinpointing deep objects...

A six month user shows a clad dime and some kind of non-precious metal flower as examples of his finds back when his unit was amazingly deep...

Some people have been sending in their detectors multiple times for repair and not getting them fixed...

These are all things Marc said or implied in his posts.

I'm no shill for Garrett, and the only thing they ever gave me free were a couple of battery holders back when I had a GTP 1350. I can honestly say that I think my upgraded AT Pro is an excellent detector and it is my favorite so far.

Bandit, I'll admit I'm skeptical about the integrity of this thread.
 
I would have to say that I was getting less of a response with deeper targets since the upgrade. Air tested a quarter in a EMI quiet zone at only 6" w/DD coil since the upgrade. It's a little hard to believe that they would turn the sensitivity down, but I have read in about 3 places online that people suspect that's happening because of the so-called "falsing" problem. I'm not sure what the issue is, but I know the machine worked better before. The deepest target I found was a brass Chuck-E-Cheese token in my yard at just over 11 inches deep (before the upgrade). Now I can't even detect a quarter past 6" on air test or in the ground in an EMI quiet zone? Something changed with the machine. My air tests with 1 quarter was almost 14", before the upgrade. I don't have any videos to show anyone, but I'm a highly technical and fast learner. I have found about $150 over the summer in mostly clad, and a few rings that aren't too much of anything special. The rose isn't pure silver, but it rang in the 90-92 TID range, and weighs 35 grams. I will keep this thread updated as I work with Garrett on getting the issue fixed. The thing that points to the control box in the biggest way is the fact that either the 8.5x11 or the 9x12 coils give about half the depth (depending on the target) as they did before. Another strange thing is I was trying to ground balance the machine the other day, and when I would press the button for GB, the machine started making a bunch of repeated bleep sounds very quickly-even after switching the standard coil with the bigger 9x12. Never had that problem even once before sending the machine in, and it wasn't a problem with low batteries. I don't recall the name of the woman I spoke with. It wasn't Sue I'm sure. She said her name, and I think it started with a "J" but I'm not sure. What I do know for sure is that this is an issue that they have seen crop up in the past, so I am sure they must have a fix for it.
 
@marcomo It's ok to be skeptical of my thread. I had great results with the detector before I sent it in, and it doesn't work as good now. I am putting some faith in Garrett being able to fix whatever the problem is, and trying to keep a shred of optimism. That's where you're seeing what you call "damning with faint praise." I don't work for Garrett, and I want to believe that they can fix it.

I have been satisfied with their product since I got it, until these depth problems started up.

I just want the machine to work the way it did before I sent it in for the upgrade. I think when I sent it in and told about the problems pinpointing deep targets, they may have adjusted something which affected the overall sensitivity of the machine. Perhaps the software that the control box runs on got update? If it is, I would rather have them go back to the previous version (I.E. downgrading the BIOS). I'm not sure what the problem is, but I hope they can fix it.
 
This news upsets me a little since I just placed an order for the at pro. I purchased the machine for the reviews based on the depth and the pro audio. I don't want to buy a watered down substitute. I may re think this purchase and get the f70 instead.
 
[size=large]I just sent an AT Pro back myself. I had the same symptoms as you are describing. Sometimes when I would push the ground balance button it would just start beeping real fast, non stop. At other times the detector would act like it would be working normally but it would get no depth or would not detect any targets at all. One time I dug what sounded like a real deep dime and it was a surface find. Sometimes the display would just go crazy and start flashing random numbers and the depth meter would go crazy too. This was not emi as it happened at any site I went to. It was not battery related, I tried several different sets. I reset the detector many times but it did not help. This was one that Garrett had upgraded also.[/size]
