Omega 8000 comparison between the standard coil and the NEL 12x13 Tornado - Air Tests

[ezer19]

here the results of my tests with the NEL and the standard Omega coil (also to find in metaldetector modification thread - was unable to move it to here)







I prefer the standard coil despite the larger depth performance of NEL coil
In my area, the soils are heavily burdened with every possible scrap (parts of agriculture equipment, ww2 remains, etc.) The smaller coil works here more precisely.
The internal pinpointer is also much less accurate with the NEL.

thanks for the very informative test...the Nel Tornado seems to get very good depth in the air.

The Performance for large and deep objects is remarkable. This ID mark of a german soldier was about 35 cm deep. My friends (one with deus, the other with xterra 705) missed this one Day before

Thanks ezer19.... very good information. I had wondered what the advantage would be in upgrading to an NEL. It looks like in summary... the NEL will give you more depth, proportionally to the size of the object (the larger the object, the more the increase in depth).

One of the consistent challenges I face (as others do) is dealing with the EMI. Most of my hunts so far have been in urban areas. In response, I started burying targets in my backyard at varying depths, just before winter had set in. I was wanting the coins to set a few months over Winter and test when the weather warms up in the Spring. Typically, I can go as high as 50-52 on sensitivity in my backyard... which is typically the limit on whether or not I hunt at a given site. So, I'm looking forward to testing the coins... and I'll be sure to post the data once completed.

I just purchased a Nel storm. The tornado is a 12x13 and the storm is a 13x14 to give you an idea. Should be here next week if anyone interested in that.

Thanks fireguy
I`m interested in the NEL Storm, and how you like it ...keep us posted.

The NELs has been redesigned, the Problem with the bad mounted cable is solved now. old: new:

 

[ezer19]

please look for, when buying it to get the new model!

I just bought the Nel Tornado will have it Monday.

Ok so it's snowing so not much field testing yet but here is some info.

You can max the sensitivity without falsing away from EMI. I had no falsing away from my house. But when I tried messing with it in my house the wifi router made my machine go crazy until I stepped outside and knocked the Sen. Down two notches. After that it was fine. I did some air tests in the garage and here is what I got. I tested the storm in my garage away from my router but I still had to go one notch from maximum sensitivity.

I recorded the results were I got 100% consistency with each pass.

Stock coil. ___ Storm.
Max Sen. ____ One notch from max.

Clad penny.
8" ___ 9.5"

Copper penny.
8" ___ 10.5"

Nickel.
7" ___ 11"

Dime.
6.5" ___ 10"

Quarter.
9.5" ___ 11.5"

Results on my garrett ace 250
Let me know what other info you want.

I did take it out and so far I can say this. In heavy trash (my house is 100 years old with the nail, bottle caps, and everything else in the ground to prove it.) it feels like it picks stuff up on every swing being so big. BUT took it further on my land and hit a sold dime sound from every angle, showing 8"+, and sharp sound on the pinpointer. I say it's a coin. So I'm liking it already and can't wait for the ground to thaw. That signal was not there with the stock coil.

 

[ezer19]

Now i have to go to my home Bank und ask for U.S. coins. Then i will repeat the test with omega und NEL. Fireguy, what you mean with "one notch from max" ?

 

[G.A.P.metal]

fireguy
Thanks sounds good to me,good increase in depth.
ezer19
looking forward to your tests with U.S. coins.thanks
Gary

I think fireguy means 1 notch from max sensitivity=power
Gary

 

[fireguy]

I meant I had the sensitivity 8 out of 8 (max) with the stock coil and 7 out of 8 with the NEL.

I now have the Nel Tornado 12"X 13" Coil and that NEL has turned my Teknetics Omega into a much more stable machine.
I live in the country ,but have overhead power lines running through my front yard,i got 50 aces.Under or around the power lines with the 11"DD Tek. coil i could run the sensitivity at around 50, and with the stock 10" concentric i could run the sens. to 60 with the start of EMI
With the Nel Tornado i can run the Sens. at 99 right under the power lines, and its is very stable in AT/ All Metal,with a very sweet smooth threshold sound, and in Disc.i can run the sens. at 99 and it does not make a sound not a pep till it finds a target no EMI what so ever.
So i took it into the house and got the same thing ,but it got a little chatty but not bad at all for being in the house....air tests a Large Cent good till 16" and a little more but iffy,it gets the same depth in Disc. as it does in All Metal.
The coil wire is very thick and much better shielded from EMI than the Stock coils,and much better built IMO.
I`m very pleased with the NEL.
Of course it`s bigger than the the stock coils, so it should get more depth,but it Should pick up much more EMI ,but it don`t.
I just wonder if ALL the NEL Coils have that Very Thick,Very Well Shielded Wire on them ??

That's a big jump in the sensitivity settings, I believe a lot of the aftermarket coils have bigger wires cuz there trying to make it better, I remember I had the same experience when I had my whites v3i thought the stock 10dd coil. Was awesome until I tried an sef coil I basically got the same results you did. With the new f75 ltd coming I can almost make out a nel coil in my future lol hh

Hey Gary, can I ask who you purchased your NEL Tornado from and how much you paid? I'm thinking of getting one for my Omega 8000 and (despite the 2 feet of snow on the ground) can't wait until spring to arrive.

Thanks,
Dan
By the way, I'm up in Rochester, NY, just north of you.

I sent you a PM they are not Supporting Vendors here.
I also bought the NEL Hunter from them very little EMI on that coil either .

It sure looks like the NEL coil is a great addition for any Omega user!
