MXT & Screw on Bottle Caps

A

Anonymous

Guest
I can"t tune out aluminum screw on bottle caps. I had the gain way down. The disc up as high as possible (max)and a threshold to barely where I could hear it. Even with these settings I couldn't get rid of bottle caps.(some were 2 or 3 inches deep)Is this normal for the MXT? This is my third week of using it and I have done well finding coins but still can't get rid of bottle caps. Iron and foil and most pull tabs I can get rid of. Occasionaly A pull tab will come through.Any suggestions?
 
You shouldnt be able to disc them out or you will be losing some coins too. The secret is the VDI numbers as they will not be those of a coin, close, but not the same numbers I have found out. There will be a few that will fool you too if you want some of the IH and older wheaties that will read like a IH or the new zinc pennies will. I find most of the screw caps will also be bigger sounding too compared to a coin.I also find most of the screw caps will show differnt positon on the bar graph too if you forget the numbers.

Hi AF. I agree with Rick. Learn your VDI numbers and listen to the sounds.I found a nice charm bracelet that read 7,which should be aluminum,but it sounded different. The key is,use no discrimination and learn your machine.You might want to get book called"Taking A Closer look At Metal Detector Descrimination",by Robert C. Brockett. HH,Jerry
 
I'm getting a VDI of 77 on screw on bottle caps and pennies are running 62-77. The bottle caps sound off a little higher pitch and usually bigger target read. Still getting fooled though! <img src="/metal/html/lol.gif" border=0 width=15 height=15 alt=":lol">
 
Most of us do not try to go past the stock mark--I like to run it at 3-0-clock----gain no higher than 9-0-clock-Threshold Just be able to hear it---Yes you can try to discrimanate out the bad things and the machine will do a good job--But If you start reading posts and the front of the MXT you will find IF YOU DONT HEAR THE BAD THINGS----YOU WILL NOT HEAR THE GOOD THINGS--Its is a trade off--You have to hear the bad to get the good---When you can tell the difference either by the screen or better yet by sound then you will be able to turn (Laten) what you hear see NOW INTO ENGLISH---And In a very shorter time than you think you will look back at your teacher The (MXT)---And the teacher will say----Grasshopper now that you can can grab the ball ---Go out and ravage the earth of valuables and become RICH with the pleasure of getting out into the fresh air and having FUN------Deathwind1
 
Thanks to all of you for the suggestions.HH AF <img src="/metal/html/smile.gif" border=0 width=15 height=15 alt=":)">
 
Think that's frustrating, wait til your MXT insists that a beer can is a quarter.
Time is trade it in.
 
What detector would do you think would be better--Deathwind1
 
A beer can will have a bigger sound to it than a quarter, but may show the same icon and the numbers will be close too. I find that raising the coil also will tell you the size of the target too, if you raise it 5 or 6 inches and it still sounds the same it is a lager item like a can, but if it get weaker it is is smaller target like a quarter. I wound up get a franklin half with my Explorer last year by doing this in a area loaded with alum can as it sounded big like a can , but when I raised the coil it didnt sound as big like a can and was passed over by many.
From experience you will use the VID numbers along with the confidence bars and the sound of the target to ID your target. Not a 100% correct, but will help ID you targets as which to dig and which to pass over.

A flattened aluminum can will be "seen" as a dime or quarter by EVERY detector on the market. The mass/conductivity factor of an aluminum can MATCHES the mass/conductivity factor of a dime or quarter. That's real life in the detecting world. No way to avoid it. Thus, the question arises, What detector would you trade the MXT in for that WON'T see a can as a quarter? Answer: only a detector that was totally faulty. HH jim
 
So you admit that your MXT meter isn't that accurate!
(neither was mine)
Try a detector that also has sound ID and visual ID,
and learn how to read them both.
I don't dig up "flattened cans" anymore!

Ken, the MXT does indeed have BOTH audio and visual discrimination. As for ANY meter ID, it is "biased" toward those targets we expect to find. Thus, ANYTHING with the SAME net mass/conductivity factor as a dime will read out as a dime. The meter doesn't say "Gee, the target has the same mass/conductivity factor as a dime, but in reality the target is a small brass key" or something like that. To illustrate: a guy I know was detecting at an old 1850's era gold mining camp. He got a nice signal, which meter ID'ed as a quarter with each pass. He was sure that he had found a quarter that had been lost in 1850. Nope; it was a 3/4 oz gold nugget. Boy, was he seriously disappointed that the meter had "lied" to him! (Not really!) I just happens that a 3/4 oz gold nugget (AND a flattened aluminum can) read out the same. Glad to hear that you don't dig any flattened aluminum cans; but then you don't dig too many 3/4 oz nuggets, or old quarters, do you? HH jim
 
Jim,
So, what you are really saying is, dig everything, because the MXT isn't accurate enough to distinguish
between a dime, a quarter, a nugget or a beer can!
Jim, trade in your MXT for a Fisher-Price, because you can do the same thing with one of those.
(I've been digging gold, silver and platinum since the BFO days, and I don't stare at a VDI and guess
what it is.)

the profiling feature. I would hold on to the MXT though and get to know it. I`m thinking of getting both the 1350 and the MXT next year. Both detectors have the features i want and think they would be a great combo. Just my 3 cents. <img src="/metal/html/biggrin.gif" border=0 width=15 height=15 alt=":D">
 
... you certainly have missed the point under discussion. In your first post you state "wait till your MXT insists that a beer can is a quarter." As I mentioned, because a quarter and a beer can have the same net discrimination characteristics, EVERY DISCRIMINATING DETECTOR MADE will "see" them as the same, whether using audio or visual ID. If you use enough discrimination to accept a quarter, you will also accept the flattened can; if you use enough discrimination to reject the quarter, the flattened can will be rejected, too. ALL VDI meter will see them as the same, too. That's real life in the metal detecting world. Also in your first post, because an MXT will properly ID a can as a quarter, you suggest "trading it in." How do you figure that the MXT is "flawed" because it WORKS PROPERLY? That makes no sense at all! In your second post you suggest that, instead of my MXT, I should get a detector with BOTH "sound ID and visual ID." Gosh, MY MXT has both "sound ID and visual ID;" didn't yours? Or did you miss taking note of that? In your third post you state that the "MXT isn't accurate enough to distinguish between a dime, quarter, a nugget, or a beer can." Yes, it can distinguish between a dime and a quarter; but, if a can, and the right-sized nugget, and a quarter all ID EXACTLY THE SAME, then certainly, the MXT IS working correctly. Got that? As far as me "trading my MXT in for a Fisher-Price," sorry, buddy, that WON'T happen. My MXT, and my GMT, make me too much money for that! Yesterday I opened escrow on yet another rental/investment house, purchased with cash, derived from my involvement with metal detecting. My six rental/investment properties, purchased from money derived from metal detecting, are worth some $300,000.00. That's the kind of thing that results from using the best metal detectors on the market. How many rental houses has your detector expertise bought you? Best wishes, and HH jim
 
From what I can interpret, it isn't your MXT that's malfunctioning,Jim! You obviously don't understand your MXT as well as you think you do. The MXT does not have distinctive
tones as do other detectors, the MXT does not have a accurate VDI, as other detectors do. (Whites electronics has admitted a 40% accuracy rate of it's MXT VDI). That was my original point!!
I have owned and used 18 different metal detectors, ground penetrating radar, & infrared equipment, and have been hunting for many years, in several countries. The MXT is not the detector of choice with any other precious metal hunter that I've met
anywhere, including California.
So, if you REALLY want to impress someone with your portfolio, look into some professional equipment, and
trade in the MXT!
Good Luck,
Kenner
