Can you adjust the Tejon to knock out pulltabs and still pick up nickles?

Yes! but you have to use the dual discrimination controls. So, I would try it like this,
set disc #1 to where nickels are just barely there, then set disc two just to where I tab is starting to break up a little then just toggle to check the targets.
But, just remember that those tabs if bend, or slightly larger/smaller will still get by you sometimes. And trying to work around them you will pass by some jewelry in that range as well.

I set disc #1 at the mark just above "foil" between foil and nickel, disc #2 just where a screw cap crackles. Large foil and most slaw will have a faint crackle, nickels sound clear and the Tejon will hit nickels deep (8+") in this configuration. Thumb up disc #1 to see if it's a square tab. Most nickels will disc out before square tabs, older nickels disc out higher than new ones, some up near square tabs, but they usually sound clear with no crackles. Disc #2 is used as a "coin check" for copper and silver coins, or you can set it to crackle on round (beaver tail) tabs, depends on where you are and how many screw caps and drink seals you want to dig.

I have found that older nickels usually means deeper and for a couple years now I've planted several nickels at different depths,
3"
4"
5"
6" and
7"
to find that with most all my metal detectors after about 4" a US nickel will move up the discrimination range the deeper they are.
And to add to that, a Jefferson, a Buffalo, a V-nickel, or even a War-nickel disc out at the same point if they are the same depth.

My 6" nickel disc out around screw-caps,
My 7" nickel will go as high as a Zinc penny.

And, with my fisher 1266 I found that pull tabs do the same thing!
I'm certain this is why some people hunting high disc will some time find a deep older nickel.

Don't ask me why they do that, but in my near two years of playing around with them the results keep coming back the same!
I've even posted the information on here before trying to start a topic about it, but I didn't get any response, its like everybody is thinking I'm nuts and just blew me off, well ignored me would be a better way to put.

Do some air test with a nickel,
Set your disc to just knock out a nickel at 3" then pass the same nickel past the coil at 6" and see if it isn't back in a good target response range?
My,
1266 does it,
My,
Omega does it,
My,
Whites XLT did it,
My,
Tejon does it,
and its been my experience that if they do it air testing, they do it in the ground.

MarkCZ that's some good info about the nickels.

I have dug some really deep pull tabs that were supposed to be discriminated out, but weren't. They had me thinking silver coin all they way.

I still don't understand why nickels are like that when other coins aren't?
A few years back I planted a US large cent at 8" before I planted it, it read very near a quarter, now @ 8" deep it still reads like a quarter, same yard, nickels elude me LoL!
That post I put up about nickels I named it something like,
The evasive and elusive nickels.

I would like some other people to at lest do a little air testing with nickels and disc them out pretty close to the coil then see if they come back in at a farther distance.
I may check my new to me Fisher 1270 this evening and see it nickels test the same with it, I'd be will to bit a good size bundle of money that I'll get the same results out of it??

I dug a nickel with my Vaquero at 8" one time and that sucker maxed out the disc. Blew my mind. I thought I was on to a silver dime.

 

[tabman]

Those nickels are tricky little buggers to ID and they hide around and below tabs. Finding one always puts a smile on my face.

Well, I just nickel tested my New To Me 1270 and here is what I got,

@ 2" from the coil the nickel disc completely out at a disc setting of 6 (that's a numbered scale from 1 to 10)
I get a little clicking @ 1" (moved closer to the coil)
Nothing @ 3"
Nothing @ 4"
Nothing @5"
A breaking up beep @ 6"
Better @ 7" but still not solid
Solid @ 8"
Solid @ 9"
Faint but solid @10"
Faint but good @ 11"

Well, another detector to add to the nickel test!

Square tab test about the same, but did come back in farther out than the nickel.
Disc out @ 7
and gone until about 8"

Beaver tail tab,
Clicking @ 8"
Good @ 9" on

I tested and filled in this post as I went.

Mark,

For sure a nugget in your post.

Being I am your brother I knew about the nickel testing you have been doing, but now I know why at times I have been digging some deep pull tabs. This is some really good testing information and it looks like it pertains to most detectors.

Now if we can figure out how to make this new info work for us.

Thats interesting on the nickles. I have had similar results but not all that often.

 

[MarkCZ]

To get this thread back around to topic (Tejon and nickels) I'll test my Tejon sometime to day and post the results in this thread.

Sure you can using the dual disc just takes some experimenting. Do remember older nickles such as shield and V come in lower and real deep nickles will come in higher. Also older tabs, can slaw, shotgun shells and even some nice gold rings will come in as a nickel on any unit so indeed a nickel is not always a nickel .

Hi Dan,
I haven't seen you around for awhile, its good that you dropped by for a visit.

Here is the Tejon Nickel air test results (interesting)

5.75" widescan coil.
Dialed the Nickel out @ just the upper side of 5 cents @ 3"
I got a little popping @ 2"
But, from there all the way out the Nickel stayed knocked out.

So, here is the OEM larger concentric coil,
Which I have to say seems to be about the same as the 5.75" coil, when its gone its gone. So, now if I could get a few other Tesoro model owners to do a "Nickel Air Test" then we would have better direction about this being certain models, or this is true for the WHOLE Tesoro line.

I checked tabs while I was at it, (okay I'm going to check them now)
Square tabs,
Disc out @3" and they stayed knocked out all the way out.

Beaver tail tabs,
Disc out @ 3" and they stayed knocked out all the way out.

Note,
The square tab discriminated out higher than the beaver tail tab. The square tab held in to the upper side of "TAB" on the dial, the beaver tail dropped out well before "TAB" but above Nickel

I'm surprised with this test, I've not did a Nickel air test with the Tejon sense I've had, I just figured it would be like the other I tested. The final test will be "In Ground Test" with seasoned Nickel targets.

Very Cool!

Below is my air test setup, including my swing sticks with rotating ends with two targets for each stick.

I remember reading somewhere that nickels develop a halo effect, similar to iron, the longer they are left in the ground. That's the best explanation I can find for the wide range they disc out at. I still find most of mine by the clear sound they make and the size of the target, but it is difficult to tell a nickel from a shotgun shell with a Tejon.

MarkCZ thanks for sharing you test results. A lot can be learned from testing.
