Do metal detectors find plastic buttons ?

So....Garrett rates a picture...and we don't, eh? :P


SWR......Cute ! Now you know I wouldn't forget my good buddies here ! ;D lol

Soon as I get an acceptable pic, I'll post it here first, then to Garrett. Now, does that make it all better :-* ;D lol,lol

My camera has Zoom lens, but no macro-photography setting, and the minimum focal distance is 2.6ft (.8m). However, I'm going to see if I can get an acceptable pic, using the setup found at the following website: metaldetectingworld.com If you go there, look at the list of subjects on right margin of opening page and click-on "Coin Macro-Photography". This website has some interesting subjects, especially the girls ! (That surely should put us back on good terms ! lol)

The salesperson I am communicating with at Garrett did comment that there must be some type of metal in the button for the detector to pick it up, and then asked for the pic. I'm assuming that was a preliminary remark, and the pic is just for curiosities sake. So, I'm expecting their conclusive answer to my subject question after they receive the pic.

I'm holding off dissecting the button until there is no other way to solve the mystery.

I'll post Garrett's final reply.

Todd ;D

Got a prompt reply from Garrett.....they want to see a pic of the button......I'm working on that.

Will advise asap.

Todd :)

Garrett thinks they may have created a machine that responds to plastic. Careful! They may want to take your machine and run tests on it. Phone Home, Ace 250! Phone Home!!!

Hey BuckleBoy !.............That's a good one ! lol

Maybe they inadvertently left out a transistor and created an Ace that does it's own thinking (Grrrrrr...you bad button, you can't hide from me !).

Is it painted?

I gotta tell ya' - a while back we established that detectors will detect many tattoo's... so, maybe the pigment has a metal base?

http://forum.treasurenet.com/index.php/topic,74455.0.html

Jim........No, it's not painted on the outer surface; just a plain plastic shirt button, although does have dark and light color variation. Soon's I can work up a pic, I post'er here.

Thanks a whole bunch for that link ......I may decide to share that information with my Garrett contact. Or maybe that person is a member here and is following this thread as we speak.... :o

HH !

Todd :)

Jim.........Just thought you might like to know, I just E-mailed your link to my contact at Garrett, for their info..

Thanks again !

Interesting! LOL... Tattoo detectors ...
 

Plastic buttons? Good question, because I got a pretty good signal today,dug down about 3 inches and pulled out a superball. One of the variety that you can get from a gumball machine for a dime.
What gets me is it was at least 3 inches down. In this area things do'nt sink to quickly, so that puts that superball at about stoneage depth. All along I thought cavemen played with rocks now I find a superball. Go figure.
I also dug a crappy lookin clad penny just below it. Now how the hell did a caveman get a 1979 penny?
I tell ya, this hobby really has me scratching my head.

Hi muleskinner !

Scratching our head kinda goes with this hobby ! lol

I guess a "superball" is a gum ball, not a lucky prize from the machine....was never a gumball addict, although my daughter-in-law sure is ! ;D At any rate, assuming superball=gumball, then your detector signaled on the penny, and the superball was just "icing on the cake" ! lol

Attached is a document that deals with the sink rate of coins that might help to understand why items of different material densities sink to different depths.

Of course, there are many reasons, other than material density and sink rate, why your superball was that deep. For example, when fill dirt is brought onto a site, it often has items in it, usually trash, and after the dirt is spread these items could be left at unusual depths for the items involved.

As mentioned in my reply #21 in this thread, I don't currently own a camera with a macro setting for extreme close-up photography....my camera has Zoom, but the min. focal distance is 31.20". Today, I made a setup to position my camera lens, at full zoom, exactly 31.20" away from the button. My setup was like the one appearing in the "Coin Macro-Photography" article that appears on this website : metaldetectingworld.com , except for the distance. Unfortunately, my camera wouldn't bring the penny image in close enough for good detail, so tomorrow I'm going to barrow my son's macro camera that has a min. focal distance of 14.4" (1.2ft) and a zoom lens. Hopefully, this will get the job done so I can post a pic on this thread.

Well, I have to close for now......hope this helps !

Todd
