<img src="/metal/html/smile.gif" border=0 width=15 height=15 alt=":)"> Took my new MXT out today. I havn't used a metal detector in years. Managed to find 29 coins, all new ones.One problem. Occasionally it would show at 80 or 90 on the vdi and the depth at o inches. This would happen even with the gain way down and disc above nickel setting.This was in coin mode. I would dig some and check and it would still be a good strong signal but showing 0 inches even when I was down about 8 inches. I finally dug it up and it was a flat aluminum can about 10 inches down. This happened several times and the clue was it always read 0 inches. I didn't dig any more completely up to confirm if it was a can or whatever. After about 6 inches down I gave up when they kept reading depth at 0 inches. Anyone else had this experience? (the ground mineralization was running about 60 in all locations.
 
The depth calibration is set for dime-sized targets; larger targets will read much shallower then they really are. Therefore, yes, aluminum cans can give "0" depth readings even if they are about a foot deep. This is NOT a problem, only a challenge. Hope you do well with your new MXT. HH jim
 
Ok, Thanks Jim. That explanation sounds good to me. I guess you have to break the surface to confirm its not a coin or whatever????
 
A good pinpionter would help.If it reads shallow and you can't find it with your pinpointer it's usually something big and deep. A sprinkler head will read like a quarter on mine. HH,Jerry
 
As Jim indicated, the depth is calibrated for coin sized objects. Like you, I dug up a lot of flattened soda cans, or worse, cans that have been shredded by a lawnmower.
Now a days, If I get a shallow reading (not always "0" in my experience), I'll use either my pinpointer (for depth reading of 1" or less), or my probe. If I don't get a hit from either, I move on. HH
 
Guess it has happened to all of us, I have found that 99 % of the time if it reads 0 depth and the coin aint on top of the ground or just barely covered it aint a coin. Very rarely will any coin read 0 depth. Good luck.

.... is to do a depth reading as you slowly raise the coil off of the ground over that target that read at that "0" inches depth. If the depth reading goes from (say) that "0" depth reading, to (say) 2" depth reading when the coil is now 6" off of the ground, you know that the target is something much bigger than a coin. Another way is to just sweep the coil over the target, but at maybe 8" off of the ground. If there is still a good signal, the likelihood is that the target was bigger than a coin. But.... that doesn't necessarily mean that it is junk. Remember, discrimination, either audio, or visual, is merely a tool. Following the adage, "When in doubt, dig it out" has put many a smile on a detectorist's face when that "probably a piece of junk" target turns out to be something nice. HH jim
 
I passed over a big target next to my house for months. I finally dug it and it was a kids penny cache!! Broken up jar with metal lid and 100+ pennies!! You just never know <img src="/metal/html/biggrin.gif" border=0 width=15 height=15 alt=":D">

At an old ghost town site on private property, I got one of those "half-good, half-bad" kind of signals. The audio was confused, the VDI was confused, it was thus one of those signals one would usually ignore. And, since this place has really been "hammered" over the years, I knew that likely dozens of other detectorists had ignored it (since it was undug.) Well, Little Jimmy decided that "when in doubt, dig it out" was a wise decision, so I dug it. It was a man-made item consisting of iron and brass components. Although in less than pristine shape, a though began to occur to me that I did know what it was. The letters W.U.Tel.Co., in fancy script, were imprinted on it. "Western Union Telegraph Company!" It was a telegraph key! And, I knew that I was detecting on the particular spot where, in 1882, Wells Fargo and Co. had their telegraph office. Cool find! "When in doubt, dig it out" often pays off.
