Interesting video Sube! Have you tried swapping the tab and the dime? I assume the shallower target would control the signal?
Thx,

Controlling the signal no it's just keeping the return signal on the dime from being strong enough for the detector from seeing it .As the dime gets shallower say 2 inches you would start to get a return signal on the dime directly under the tab even but the vid would be lower say 12.35 because it's a blended target now .If the dime was deeper say 6 inches the signal on the dime would be even weaker there by making the area around the tab wider than the 16 inches as compared to the dime 4 inches .
Now you wonder why you can find anything when the ground is covered in trash because they are not evenly distribute there are holes in there where you can get good signals .It's not just tabs nails bottle caps it's all things that well block the return signal of the dime , that means it's got a stronger signal than the dime and the dimes signal being weaker can't be seen by the detector .
But most places that I find the tabs and caps are 2 to 3 inches deep already there by letting me find the coins at 4 to 5 inches next to tabs or bottle caps nails thank God are almost always at coin depth or deeper allowing you to find that coin as deep as the nail except where a old house or other structure was removed and the nails are just starting to sink . This is where a strong magnet is advised to remove as much of the surface nails as you can before hunting.
Now as for picking a coil for the job think of it this way you just went over a tab there's another tab 8 inches away from the last one your coils 11 or 10 inches wide and long you will be picking up the last tab with the tail of the coil killing the signal between the tabs you could of heard with a 6 inch coil so many scenarios and ways the junk lays in the ground .The coiltec coil being only 5 inches wide would be better on a east west hit than the 6 inch but look at the tail part of this also .If they would of built a 4 by 6 coil I would be all over it but they built a general purpose coil which is not optimum for trash or big areas kind of a in between coil trying to get the best of two worlds .
So if you see that tab laying there pick it up you may get a present surprise .
You see all these videos where the guy is doing a nail board test with a deus when he gets to the nail with the dime next to it east west hit he trys to get a signal with the tip of the coil which he does but when he goes over it with the center of the coil it sputters out .I would really like to see a test like I did with the ctx done with the deus any takers .That's coins at depth with a target above . Just wondering if speed has any effect on the test I did .I don't have a deus but it would be fun testing one .As far as technology minelab is the only detector that can actually see a coin under a nail on a west east hit depending on the size of the nail where the nail signal won't over ride the coin signal. But I wonder what deus is going to release in there update I can almost bet you minelab is working on nail under coin thing right now maybe a UPDATE or a new detector . :thumbup: sube
