Tesoro Tejon Two Coil Air Test, NEL Sharpshooter WS & Tesoro 10"X12" WS

[MarkCZ]

Well, I'll put the NEL results up first.

No WIFI,
No Furnace,
No florescent light,
No Computers,
I also added a bunch of items to the test.

Tejon,
NEL Sharpshooter coil 5.5"x 9.5" Widescan
Sensitivity = 9
Discrimination = the F in Foil
Rechargeable Batteries.
Repeatable, dig signals. no one way hits,, didn't count any swing three times hits only once either.

Clad Coins
US Clad Quarter =___9.5"
US Clad Dime =_____8.5"
US Nickel =________10.5"
US Copper Penny =__8.5"

Silver Coins
US Silver Quarter =_8.5"
US Silver Dime =___8"

Canadian Coins
Canadian Quarter =_9.5"
Canadian Nickel =__9"
Canadian Dime =___8"
All the Canadian coins would stick to a magnet!

Gold Items
Mans 10K yellow gold wedding ring =_____10.5" (compare this to the low conductive US Nickel results, I rechecked this a couple of times)
Woman's small gold loop earring =________7" (closed loop)
Woman's small gold loop earring =________4.5" (latch opened all the way, but the same earring)

Below is pictures of the items I used,

Tejon with the 10"x 12" Widescan coil
Sensitivity =8 (at 9 the chatter was to bad)
Discrimination = F in foil
Repeatable would dig signals, had to hit in both directions and not just hit and miss.

Clad Coins
Quarter =____10.5"
Dime =______9.5"
Nickel =_____12"

Silver Coins
Quarter =____9.5"
Dime =______9"

Canadian Coins
Quarter =_____10"
Dime =_______7.5"
Nickel =______9"

Gold Items
Man's 10k yellow gold ring =__12"
Earring Closed =___________6.5"
Earring Open =____________4.0"

Looks like the 10x12 is the boss on the Tejon huh?

 

[bik-il]

Thank you so much for your efforts!
A lot to think about.
Much to be said about Tesoro coils on Tesoro machines...

Yea, as far as depth on coins and larger gold but it did lose some sensitivity to the smaller gold earring. And I'm pretty certain that the larger coil would lose out in areas that had a lot of trash to work around.

And to note! Tesoro did an amazing job at trimming down the 10"X12" coil and its not very heavy but even at that it still makes the overall package really nose heavy and puts a fair amount of increased drag in swinging it.

You know Rob, the low conductors seem to even have a more "Robust" response, and I've went back and retested them with the same repeatable results.

I took that little earring and tested it with my Omega and here is what I got from that!

Omega 11" DD coil
Earring Closed = 3"
Earring Open =__0" (Nothing)

Thanks Mark and Ron.

Thanks Mark and Ron.

Your welcome!
And my offer still stands for those clips and to sweeten the deal I'll toss in a "Brand New" flashlight as well.

Yes, thanks for posting the test results.

I haven't done comparisons recently, but when I did compare the 10x12 with the stock 9x8 they were nearly identical in air tests. The advantage with the 10x12 is total swept soil volume, while it's disadvantage is weight and dealing with trashy, dense target environments.

If I read the specs correctly on the NEL site, the sharpshooter is about 14 ounces. If my memory is correct (no guarantee on that!) the 9x8 comes in at about 12 ounces and the 10x12 is around 20 ounces. So, with the NEL, there should be a fairly good increase in total swept volume with just a little added weight compared to the 9x8.

My observations across the Tesoro coils have been that the concentrics tend to discriminate a little more cleanly, isolate targets very well and give a little better audio clues than the DD's.

Looking forward to some field observations on discrimination, target isolation and target sounds with the sharpshooter.
Cheers,

Mark that would be handy to have a dedicated light, I bet there would be more folks interested also. Since you are not working, and I am funny about freebies, I would like to purchase one.

Well, I'm still working but they are still closing the warehouse, but its my understanding that they have to give us a 60 day notice and that's not happened yet??
You know if I send you a $2.00 light and the clips and my return address is on the box and get a Money Order in the mail for a million bucks I would probably spend it wisely and go metal detecting a little more often

I am getting similar results air testing my Vaquero with the same coils. There is a depth difference (although in air to me really does not mean too much other than to get a gauge), when running 'supertuned'. I experimented running full sensitivity and backing off the threshold a bit, and then a little less sensitivity and full threshold, and then totally 'supertuned' and full blast did get the best results.

Tell you one thing, the bang for the buck coil, in my opinion, is the 5.75 widescan. That thing rocks..

One more thing. I was testing some gold rings, pendants, earrings, etc. with the NEL and 5.75 widescan against my Vista Gold with the small and bigger coils and the V, in 'supertuned' mode, was very comparable. The Vista Gold did hit harder on the smaller gold, but the depth differences were minimal. Obviously it was only a depth test, so there were no tests done to compare recovery speed and separation capabilities.

Would love for Tesoro to add a mod to the V for 2 tone audio break. That would be nice.

Traded a few detectors for a Tejon so I got one coming and will do some more comparisons.

[KVM2]

Thank you for taking the time to do those tests...I had wondered about adding a Tejon to complement my "V"...Maybe a ??

 

[SWMO Mark]

Thanks for the results. Although the 10x12 is almost double the size of the NEL coil. The 10x12 should get deeper because of its larger size. Mark

Hello Mark! This is Tallon. I just did an airtest on my Tejon and the clad quarters should be coming up at 13", nickels to 14", dimes to about 12" and I didn't bother to test pennies. Just concerned that one of your settings may be toned down just a little too low but not sure which one or (ones) they might be. Also, I'm using the optional 10X12" Tesoro DD Widescan coil that you used. If you can't seem to tweak it any further, you might have a Tesoro qualified technician (likely would be your local dealer) in your area that could re-adjust your internal sensitivity pots for (maximum) sensitivity. I had my dealer do that many years ago for my Fisher 1266X and that thing REALLY went deeper after a few internal adjustments. The 1266X is already legendary for being a hot detector and can't be found online for less than $300.00 unless one's maybe very lucky. Also, Tesoro themselves should be able to make some internal adjustments if you were to send it to them in Prescott, Arizona. By the way, Jack Gifford, the founder of Tesoro in 1980, worked as a technician for Fisher before he founded the Tesoro company. Well, good luck with this issue as I don't mind trying to help coinhunters like yourself or anyone else who are serious and don't mind a few extra tips to get the most out of their machines. Good luck and Happy Hunting! SINCERELY, Tallon.
