What to do with 11-47?

Am wondering what every one does with strong repeatable signals both ways that when they are dug the machine cannot find anything? I have dug countless #'s that cannot be found even in all metal wide open?
 
what happens to the signal - it just disappears after you dig the hole?
if so, does it come back after you fill the hole back in?
do you dig and keep scanning until the signal stops and then check the dirt? have you used a probe?
interesting...
 
After the hole is filled in there is no signal. And there is nothing down in the hole. I am not using a probe since I am digging ghost towns and dig with a Japanese pick and dig a hole big enough to get the coil down in, 5" stealth. But on other occasions in yards the probe cannot find anything either.
 
Firstly . . . this is not a phenomenon that I have ever encountered. Secondly, it has me intrigued. Are you hunting near another detectorist? If so, how close is she/he? What kind of machine are they on? Have you tried noise canceling before the hunt?

If that's not the case, I have had dimes on edge in a pile or in the wall (usually 12-45 to 12-46) where I would have never found it without using my sunray probe and moving very slowly and even reaquiring the signal several times to get a new lock. A solid repeatable 12-47 deeper than 6" gets me pretty excited and 9 times out of 10 it's a sliver quarter..

Looking forward to hearing from others who may have encountered this. The only other thing I can say, is next time this happens to you, switch to quickmask and check it with no disc . . see if it starts showing up as a 35-47 instead of a 12-47. Iron masking could possibly be a cause as well.

Long story short. Get a probe. You will save yourself alot of headache. Object on edge or something as small as a BB.
 
I have had this happen,and have found usually its the halo effect of a piece of iron very deep,and the signal goes away when the soil is removed.
Next time, try and just keep digging and use your probe.
Also look for that orange colored dirt where it looks like something has rusted away to nothing.
 
What kind of probe are you using?
 
The probe (if you don't have one is almost essential). My other thought is you might actually be "knocking" out the target with the pick....but I'm going to assume you're more careful than that. One thing I'd maybe try is getting a real good pinpoint, then taking an inch or two at a time, checking with your detector and see if you can't "sneak" up on your target. 11-47 can be those darn zinc canning lids, they'll show up as a 46/47/48 Co number at 6" and actullay be around 12" deep. They're real pesky. Other 11-47's are aluminum liquor bottle screw lids, battery terminals, larger copper pipe pieces. Aluminum cans also hit there from time to time.

I agree - I don't even want to detect without a probe - I even have a backup probe in my vehicle. So many things I have found with just the probe! Once you open that hole, the Minelab can have trouble with all that air space.

If it were either very deep iron or a deep pipe - when you stick the coil down in the hole using all metal, then you should have picked it up.

Is it possible you were getting an "echo" signal from a piece of trash (like a whiskey or bottle cap) nearby? Sometimes when these items are buried at an angle or sideways, they can give you a false echo signal next to their actual location.
 
I have to assume you are hunting in CO sounds.

Next time you get one of those signals switch to 2 tones, ferrous sounds and switch to the relic pattern and see if youy still get a non-ferrous tone. If you do, pinpoint it and see if it moves when you do. If it pinpoints at the same place where the ET said it was in disc then (get a probe) pinpoint with the probe and see if it is something really small on or at the surface. If it is still in the hole dig a few inches at a time until it no longer pinpoints. I would recommend, if you have or can find one a pocket uniprobe because it tends to focus all its "probing" right out the tip. The Garretts is a good probe but it probes 360 degrees all around the shaft so if it is minerals it can be confusing, seeming to be everywhere and nowhere.

If you're hunting in CO.Mulit I think switching to FE/2-tone will clear it up but only if you use the relic pattern or null out the bottom few lines of the screen.

I'd like to hear about it if you figure it out. 11-47 has almost always been a quarter for me, sometimes silver.

The E Trac will pick up really tiny objects ....Sometimes too tiny !!.... I use to dig those holes and my partner would call them ghost holes ...... They are etiher something very tiny that you're missing or a halo that gets disturbed when you dig , it pulls the halo apart and is undetectable at this point ..... I don't want to sound redundant here, but you really need to get a good probe !!....It will not only help in location of a target , but will save you so much time and energy ...Jim
 
Sunray X-1 Probes Is just like a mini detector in the hole not just another pinpointer :) Once you get one you will never go back and you don't have to worry about batteries ect ect....

I will second this opinion. Having hunted many old ghost towns, rusted away iron can cause a false. Watch for the rusty iron 'blood' in the soil.

Another problem is tiny bits of bird shot, .22 bullets and other tiny surface signals that are so small, they appear to be a small and deep coin to the detector. When you get a signal out in one of these ghost towns, try kicking away the top 1/2" of dirt with the side of your foot and see if the signal moves. If so, you know that you have a tiny target on the surface, If it stays, something bigger. If the surface doesn't allow you to easily kick away the dirt, use your shovel to remove a small amount of surface dirt. Either way, you will find the culprit.

Also, remember to do your pinpointing in all metal mode and continue looking in all metal mode during the recovery process.

One more thing, I found that the factory E-Trac coil is incredibly sensitive to adjacent targets. If your disappearing signals are strong, try lifting the coil and make sure that you are over the target and not adjacent to it and picking it up on the periphory of the coil.
 
Thanks for all the suggestions a lot of great things to try.
I usually use the Garrett probe when in manicured lawns. But where the cow pasture doesn't need the tender care I am not using a probe due the excessive digging of 20's up signals,lead bits, and YES the miserable tin jar lids disintegrated and whole, tiny boot eyelets, hosiery clips etc the list goes. But needs to all be investigated! I am noticing the halo effect of the rusty tin cans and today was finding the cans or whatever is left of it off to the side of the hole but would not signal in CO. I usually run in CO factory coins pat. with the top line blacked out except 46 up. 2 tone ferrous manual sen. In all metal, blocking 1&2 and 2 lines up on the bottom.
