Question on Target ID

A

Anonymous

Guest
Can anyone tell me why beer cans show up as good targets on the id meter? is it the aluminum? I have been reading but have found nothing on it. Thanks Ronnie
 
.....as the size of the target. What you are experiencing is the "overload" that the signal is producing on the can, making it override the discrimination circuits of the detector. The aluminum itself is the same as what is used in pulltabs, but the size of the can keeps the detector from discriminating it out at the same discrimination level. A matter of "conductance rather than conductivity". The larger target produces a stronger signal, thereby making it harder for the detectors discrimination circuits to identify it or discriminate it out.
Hope this helps with your question.....
 
While I use an Eldorado w/o TID Ralph is right.
Somtimes though not always I can hear a difference in the sound of cans as oposed to tabs.
Aluminum to me often has a different sound from coin targets. Will try to describe it though it may sound different to you.
Aluminum seems to hit with a sharp bam then a second sharp bam as it tapers off. Coins have a smoother lower tone.
I know I am not describing it well but it is normally distinctive.
Try it and see if you don`t notice it?
Have yet to own a TID unit but I think the audio disc is as important as the display information.
 
Some time ago, a world famous relic hunter, owner of a different web site, was hunting with his father. This world renown hunter got a good strong signal but decided to pass it up thinking it was an aluminum can.
Well, along comes his father, who decided the signal was too good to pass up. Yep, you guessed it. The little guy had passed up a Texas Belt Plate.

I guess I will dig them, I was just so let down at the park that day, every good signal was deep and had good tone. So I figured I had to dig them, one thing for sure the deeper the beer cans the older they were. That was a fact, I found one that had never been opened and used the old church key to open them. A Church Key opener may be a southerthing, some call it a can/bottle opener. Thanks again for the good info. Ronnie
 
..."Audio I.D." comes with experience, whether by using the slight distinctions in the actual audio "response" (as opposed to the "tone" on single-tone units) or by simply "sizing" your targets. Once you get to the point that you can audibly tell the difference between a smashed aluminum screw cap and a silver half dollar, THEN you are talking business ! <img src="/metal/html/wink.gif" border=0 width=15 height=15 alt=";)">
 
You mean one of the steel cans from the good old days...... circa 1965 BP (before pulltab) ? <img src="/metal/html/lol.gif" border=0 width=15 height=15 alt=":lol">
 
It is called the same up north or at least in Iowa <img src="/metal/html/biggrin.gif" border=0 width=15 height=15 alt=":D">
 
Right. The old ones before the pull tabs, I remember my Dad kept one of those Church Keys on his Chair on a string, and others placed in varios areas around the house and property. LOL He had church keys on everything.
 
I did learn the difference today in big and small targets. I am very impressed with this tesoro cortes though. I got a hit today and it was pretty strong considering how deep it was around 10-12 inches down wet ground. I dug and dug and could not find the target the pinpointer was not saying a word, but when I ran the detector over the spot it would id something. Having faith i kept looking and after about 20 minutes of scratching my head and cussing I found it. To my suprise it was the shell casing of a 22 caliber shell that had been cut in half. Smaller than your pinky nail and it was that deep. The cortes was smarter than I was, when I was ready to give up it kept an id on the target not letting me quit. This thing is something eles.
 
Ronnie,
Here is a beer can signal that a friend of mine dug up about twenty years ago.
He said that he passed over it, thinking it was too loud, but turned around and decided to dig it.
It is solid gold and quite beautifully engraved.
Need anything more be said?
I dug a 2" deep U.S. Morgan Dollar a few years ago in a well-worked park. It to was very loud and would have been easy to pass up . . . thinking it was a can or other trash item.

And it happend this past spring. Someone I know was doing a site beside a busy highway. As things started to get quiet he walked to the ditch and started swinging. First signal...pop can, <img src="/metal/html/frown.gif" border=0 width=15 height=15 alt=":("> 2nd signal... license plate, <img src="/metal/html/frown.gif" border=0 width=15 height=15 alt=":("> ... 3rd signal pop can, <img src="/metal/html/frown.gif" border=0 width=15 height=15 alt=":("> 4th signal valuable beltplate! <img src="/metal/html/oh.gif" border=0 width=15 height=15 alt=":O"> <img src="/metal/html/indifferent.gif" border=0 width=15 height=15 alt=":|"> <img src="/metal/html/oh.gif" border=0 width=15 height=15 alt=":O"> What scares me is after two junk hits I would have probably turned around and left. <img src="/metal/html/cry.gif" border=0 width=40 height=15 alt=":cry">
 
While aluminum cans give a real good signal they are easy to identify prior to digging. While I am using audio only (GS2) every detector will give you enough information to decide whether or not to dig. In particular if you are new or using a new machine, you should resist the temptation to dig immediately. Analyze the signal. Measure the width by slowly going over the target and see if it shapes out can size. Do this at 90 degree angles. Listen to the audio and see if it sounds sharp on the start and edge. Kind of like BBEeeeEEPP as opposed to bbeEEEeep. Record what your TID is showing you for future referance. Carry a probe (mine is a sixteen inch piece of brass welding rod) and vertically prod the ground several times to get an idea of the targets size and location. If you can extract it without doing significant visual damage (we don't need park bans!) do so and verify the item. You now have a good idea of what a can signal is going to ID and sound like. As you gain experience, if you come across a can signal that IDs or sounds different it may be masking additional targets. Resist the temptation to dig a solid signal until you have analyzed what your machine and experience tells you is the most likely target. Experiment with sweep speed and lifting the coil over the target to gain additional clues and knowledge. The best target ID resides between your ears. Either save the can for test garden purposes or dispose of it like it should have been in the first place.
 
I see we all have our opinions on what to dig and what not to dig. To be or not to be? LOL. With my lack of experience and from all the help here I am going to keep diging those items. Just like that picture, you really never know for sure. Thanks ronnie
 
Yeah Joe it don't pay to pass up a lot of these signals. I once dug up a flattened out beer can full of probe holes. Underneath it was a roll of silver quarters. Lot of boys passed that one up.
