Hi everyone, I am new to this forum, and of course - need some advice.
My request may seem a bit strange, since most of you search for other much more valuable things than sewing needles .
I need to buy a metal detector for my work/hobby as a tailor. Its main purpose is to detect sewing needles or pins in the things I make. I do not want it to be a large standing machine (as are used in big fabrics), but rather a regular detector. For the last weeks I have read a lot, called some sellers, and I know that pinpointers and hand detectors in general are not sensitive enough.
So finally I decided to buy one of the 3:
- Garrett AT Gold
- Teknetics T2
- Teknetics G2 (a clone of Fisher Gold Bug Pro)
Please, help me making this final decision. Which one would be most sensitive - for detecting small sewing needles from a distance of at least 3.5 inches?
I have called sellers, but they just won't open the boxes and check it for me. So please, based on your experience, and knowledge - can you help me? If any of you would like to help me even more - you could check, what is a distance from which your detector sees a small (about 1.3 inches) needle or a pin.

My machines are probably a little expensive for finding needles, have you tried giving Regton a call to see if they can help?

Yes, these are pretty good devices, I realize that. But I thought, they could serve me also as normal metal detectors for treasure hunting. But my big concern is that they have to be able to find a needle.
I have not called Regton, I rather called smaller shops with a request, that they did the needle-test for me. But they could not help me, because they had the detectors packed. For me the most valuable would be opinions from owners - I imagine many of you find trash, tiny objects. And that information would be of use to me.

Best bet would be a detector with a small coil in all metal mode using pinpoint to scan the garments, it means you have to buy a smaller coil but could also use the detector for searching.

As I wrote, pinpointers and hand detectors are not sensitive enough. I had it checked. It was easy, since they are widely used. Not easy to check bigger devices, that is why I am troubling you guys.

Thank you. I suppose it directs me toward AT Gold, that has smaller coil with it. T2 and G2 come only with 11'' coils, and if I wanted a smaller one, I would have to buy it extra.

I have a fs2 and I tryed with a small opened up staple one inch long not got a dressmakers pin it picked it up at 3" in descrimation and 4" in all metal that's using the stock small coil if that any good
-
I have a 56kh makro gold racer and using a needle with thread I am getting just over six inches on the standard 10 X 5. 5 inch coil.

Thank you so much. That is a creative idea to use a staple. And the results are good, I must say. I imagine a needle would be easier (maybe not much, but at least a little) to detect. I went through fs2 specifications. Is this device similar any other detector on market? And what was the coil's size?

Thank you! That is a very satisfactory result for me. I considered makro racer (and gold bug 2) for its high frequency, and once again I see, I should reconsider my decision. The only thing that was against this choice - was a thought that it is so specialized, that I won't be able to have any fun if I try to do some generalized searching for fun.

The makro gold racer- It's so easy to use. It's mainly a gold detector and finds very small objects as it runs at 56kh. There are three modes . All metal, disc 1 and disc 2. It will find a a gold earring stud at 5 inches. It is really designed to find very small objects Such as a needle etc .
-
The fs2 is a goldbug clone and I used the 4" coil
-
Also, I have a 2 questions that bother me.
1. Do I need to go for higher frequencies (around 70-90 kHz) to have more sensitivity on small objects? I know, that some specialized in gold hunt units have really high freq (as Gold Bug 2 - 71 kHz), but others have much lower freq (AT Gold - 18 kHz). And both have very good reviews on sensitivity in detecting gold nuggets. Is there a simple correlation: more frequency = more sensitivity on small subjects? I must remember, that I do not only need to detect a needle, but also need to detect it from a certain distance. Is there any advice for me concerning the freq?
2. How it is, that certain units have true all metal mode and some don't (as far as I understand - they just have zero disc mode). So the true all metal mode should give me a raw input, and it should be better for my needs. Still I do not understand, why some units lack this true all metal mode - is this option hard to obtain by a manufacturer? And how do I tell, if a detector has it or not? As far as I can see, only AT Gold has it clearly stated in specification sheet.

What about a second hand XP Goldmaxx Power. There's plenty around, you will get the depth and the buzz for your targets, and it will make a great machine to enjoy the hobby as well.

You think? I would have to have an information on its performance on a needle. I did consider it, but then I read that XP would do better. I did not want to buy XP, because I did not like the fact, that it is wireless, and all the trouble with changing batteries every 2-3 years. And that is why I gave up on XP. But if Goldmaxx did well - I would take it.

Why not try a pulse induction machine I use one for the beach and it loves small things like fishing hooks and wire and hair pins :)

Only just saw this thread, we get the same request very often, get in touch with Goering Kerr Scotland, Lock Industries or Eriez Magnetics for textile needle detectors, the type of detector you need is quite specific, most 'normal' detectors will pick up some but not all of the textile needles due to different types of steel being used within the industry, stainless needles are impossible to detect as are hypodermic.
Hope this saves you some time & money.

Most good PI machines are expensive, and fairly speaking, and so far, I have no received any signals, how well it could actually do with a needle.

Nigel, thank you. I didn't consider an industrial metal detector because of its price, size and lack of versatility. As to small, hand detectors such as falcon md20, and ProGrade, I saw some presentation, read specifications, and they did not seem very encouraging (noisy, short distance). They did not seem to perform any better than would a regular metal detector do, and a regular detector could be of some other use to me.
But I admit, I have not contacted the manufacturers for advice - I just relied on the information I could find myself. I will write them an email, and see. Maybe they could fine me something reliable, but not extremely expensive. Still, I'd rather buy a regular metal detector.
And now I see, I own everyone an explanation. Sewing is more a hobby, than a regular job to me. I do it a home, several products a months. And I always try to be on the safe side. That is why I need a MD, but also why, industrial solutions seem not for me.

I understand your situation Klaus, no problem, the industrial units were all PI type technology but not the same as our hobby PI's, there used to be a detector from Protovale (another manufacturer I'd forgotten about), they had a hand held unit called a Textec, Google them ?

I tried to google the unit, but no luck. I found the company, and checked. The closest to what I could use is a device dedicated to checking wood for nails. But the specifications they gave were not better that any regular detector would do.

So guys, I just learned, that G2 does not have true all metal mode (to my shock). I am actually confused, because, it is not a easy information to find (whether a device has or does not have this mode). I don't know, what is better - to buy a device with lower frequency (like 13 kHz) but true all metal mode or a device without true all meta mode, but higher frequency (like 19 kHz). I am asking, because both of these properties (high frequency and true all metal) are supposed to make a detector more sensitive toward small targets. And besides AT Gold (which does not suit me, because the test results people send me are not good), it is not easy to find a device, that has two of these properties.

If you tell me exactly what you are trying to achieve I can try it with my racer gold. You will have to let me know what real world tests you are trying to achieve.

Here is exactly, what I need to have checked:
- Air test, in which you measure the distance from which your detector detects a sewing needle in best sensitivity you can get (i.e. all metal mode).
- The needle must be no more than 1.3 inches long, and narrow in diameter — just a regular in shape, small sewing needle. If you don't have a needle, use a sewing pin instead.

Just tried my kids bounty. 2" on the needle.

i would suggest the whites gold master (GMT)
http://www.whiteselectronics.com/gmt
48khz machine, will detect smallest bits of metal ....
rumor says that there also clones available somewhere ....
