Is your AT Pro doing this ?

[synthnut]

I'm wondering how many folks have an issue with their coils like I do ....Please check your coil and respond .....Thanks , Jim

Yes sir mine is doing the same thing.................... NOTE BUT after i checked all my other detectors the 1500 and the Sovereign they did the same thing also.

 

[dogpound]

i think i'd let garrett know about this problem...that shouldn't be doin that, that would drive me crazy in about 2 minutes.

synthnut, this is not a real issue, this a perfect normal behavior for a very SENSITIVE metal detector working perfectly in a RF rich environment, in air, inside a building wired up like a powerhouse. It is NOT indicative of your hot-spot metal detecting grounds in the ole' abandoned amusement park out in the woods near Someplace, Earth. Some would say it is not working perfectly, but they do not know the facts. In your video, the unwitting metal detector does not know that there is no Earth one or two inches below the coil. It is in air, no ground below, RF flying all over the place, it's like a fish outa water. Detectors are designed to work with the coil one or two above a planet, mainly Earth. Bring 'er out to the site, gb properly, keep it to the ground and man, it'll be smooth as silk and deep. Do not worry about this behavior. Many good quality sensitive metal detectors, and low quality non-sensitive metal detectors, do EXACTLY what you show.

Never forget, it's a Garrett. Try to do a video of this with the coil one or two inches off the ground after a good gb. You will see it is okay. Trust me. Your video is a good example of why you cannot get accurate results air testing on coins, especially inside buildings with 120VAC service running amok. Your video is a very good example of why you should not air test metal detectors indoors for any reason. It just aint gonna tell you nothin bout no detector performance.

my coil will do that if i wobble it but in the field its not a problem it works great in the ground
no problems
like gleaner 1 said its a very sensitive detector
take it out hunting & watch it work
good hunting
walt
p.s its a coin & jewelry magnet

My AT Pro does the same thing in the house as does a lot of my other detectors but outside GB on the ground all strange sounds stop. The coil is an antenna and what do antenna's do?

gleaner1,
Thanks for your reply ..... I appreciate it ..... While the coil does calm down in a "real world " situation , it still continues to false when changing direction, scrubbing the coil , or bumping into anything ..... Some folks have told me to slow down, don't let your coil scrub, and don't bump into anything ....... This is hard to do when you have miles of beach to cover ...... I've had other machines that were less powerful , and also more powerful , than the AT Pro, and they have DD coils , and they do NOT exhibit this kind of behaviour .... Later today when the sun is out , I will do another demonstration far away from any homesite .... I agree that there will be much more interference when a detector is inside of a dwelling , but it would also be falsing and making a racket when sitting still ....This coil does not exhibit any problems when at rest ..... Thanks again, and I will get back to you with another demonstration .....Jim

Hi Walt ,
Do a ground balance , and then drop it down a bit from there , and see how you like the way it hit's coins !!....It's a MONSTER !!.....As I said, I have other more powerful and more sensitive machines that do not exhibit this behavior ...... The coil still works and finds targets, but is not optimum .....It could be more and not false ....Thanks, Jim

Garrett is aware of this issue and they say it's normal ...... ??

 

[synthnut]

Does anyone have an Ace 250, or an Ace 350 that exhibits this same coil issue ? .......and if they do exhibit the same issue , does anyone have a SEF coil that they put on their Ace ? .....Does it STILL exhibit the same issue ? .......Thanks , I appreciate it .....Jim

I already talked with Brad online .....He said that the issue was normal .......He did offer to let me send my machine back to Garrett and they would look at it ..... I have talked with numerous people and their machines are exhibitting the same behavior as mine is, but they are still using it ..... I sent an email to Brad indicating that there would be no sense in my sending my machine back to Garrett if they are in agreement that this is normal behavior ....... It is what it is , and will probably continue this way .... You can't fix something that you don't think is broken .....The fact that they consider this as "normal " behavior frankly surprises me .....I guess I expected more from my first Garrett machine ...... I guess it's a non issue since folks are getting some good finds .....I'm still getting some good finds , but have to slow down and make sure I don't bump anything .....Yes there are other coils and detectors that do this, but I think that the ones that don't far outweigh the ones that do , and I don't think that this is your typical scenario .....Some folks are pushing it off as being a very sensitive machine .... I agree , it is a sensitive machine, but if it were a sensitivity issue , it would be noisy at rest as well as moving about .... I will probably end up using the machine the way it is .... It's beginning to look like a non issue to a lot of people so I doubt anything will be done about it ....... Jim

 

[dogpound]

i see a easy solution to this..........don't wobble your coil horizontally in the air

 

[synthnut]

dogpound ,
Why didn't I think of this sooner ? ...... .....Jim

I have a 250 with a 10x14 DD Excelerator coil. It's sensetive as heck to emf's. Around the house I would have to turn the sensitivity down or it would chatter. But, mine would do it even when the coil was still and not moving. Once I got away from power lines it was fine and I could even run at full sensitivity. A trip away from power sources may make a big difference for you.

[synthnut]

Swartzie ,
I totally agree with you, and understand what you are saying completely !!....This is the point I have been trying to make to folks on another forum ......If the coil is making noise because of electrical interference , it would chatter while at rest also .....The fact that the coil is quiet at rest , and falses when the direction is changed , or the coil is scrubbed on the ground , or when the coil is twisted in any manor , tells me that there is a coil issue going on here ..... Then eveyone tells me to send the machine back to Garrett , who is already telling me what I am experiencing is NORMAL !!.....They can't fix something that they say is working normally !! ..... So I will just wait until an aftermarket coil comes out , that does not false ......Either that or just hunt gingerly with the AT PRo and pretend that everything is OK ... Jim

 

[dogpound]

whatever the problem is i hope its taken care of by garrett or there is another solution. i plan on gettin the AT pro in the next month or two as my water and beach machine and would hate for it to false from every wave that hits my coil or lower rod. this is one of the reasons i'm holding off until i hear more water reports

 

[Ray S ECenFL]

Interesting post. The AT Pro is on my wish list, but I think this "Normal" problem would drive me nuts. I would like to find out if changing the coil solves this problem.

I can understand if you bump the coil and get a reaction, but not just waving it in the air like you did in your video.

Think I am going to take a wait and see position for the time being.

Thanks for sharing your video.

Dog as Syths friend and hunting partner. The AT has been hunted outside and away from electrical interference. The fact that if you scrub or bump your coil on the sand it falses. At the end of your swings it falses etc. What you see in Syths vid is NOT EMI. Trust me i know i had a F75 for a long time.

 

[kwdstalker]

like you have been told on other forums about this is why don't you and everybody else send them back to Garrett free of charge and have them check them out.if there that many bad ones out there and were all sent in Garrett would have to look into it faster then just a few complaining on forums.

 

[John-Edmonton]

While you are still telling everyone how bad (you think) your detector is, there have been so many posts of people getting relics in hunted out places, getting great finds in and out of salt water such as gold rings & chains and for the coin hunters....lot of clad. If your machine is as bad as you think it is, please DO something about it and send it in. That's what warranties are for. How many more forums are you going to post this same scenario?

Either that or go out and hunt with it instead of swinging it around in a garage! Maybe a person should try to learn how to use a machine before he starts running it down.
