Tesoro Descrimination

[synthnut]

I'm wondering what Tesoro machine has the best descrimination .....I'm talking to more people with Tesoro's who's dsscrimination is not all that ....... I'm still messing with my brothers Silver Umax, and while it's a nickel monster , it has never done a very good job descriminating Nickels ....He went out with it today and ran the descrim up almost as high as it would go, and it would STILL not descrim Penneys !!!.....I thought that maybe he had the Sensitivity up too high , so I turned it down to 3 or so , and it was STILL beeping on Pennies !!..... I'm seeing more and more machines and talking to more and more people who have descrim issues just like me .....Is there something going on with the newer Tesoro's ? .....Are they not setting them up correctly at the factory or something ? ....... I'm not saying that they are , but I am wondering why so many machines are not working as they should ...??????.....Is there anyone out there that has spot on descrimination , and if so , which machine do you own ? ......Thanks, Jim

The silver that I have does exactly what it should. I will say, that I spent several weeks learning this machine....sounds like you may have not spent the time.....not judgin.....just sayin.

Hi Jim

I don't know of any Tesoros that can disc out copper pennies, zincs I don't know......... never tried that. I do know I want to be able to pick up on a zinc penny though, as I find alot of neat things in the same conductive range. Many of the places that I hunt in are old and all I Disc. out are small nails. Just my two zincs.

My advice to you is not to discriminate out pennies zinc or copper. I have found some nice rings in this area. Silver & Gold sometimes falls into pennies Range. If their zinc I just toss them in the trash if their buggered up. Its just like pull tabs. I try to dig everything in that range, that's were most of the Gold lies. If you don't want to dig the trash, leave it there and someone else will Like me Remember to slow down. There is a lot of Earth and a little coil

I have the Vaquero and Tejon, run the disc up as high as it will go and zincs are gone but coppers come in. I love this feature. for me, tesoro put the disc right where it should be.
my sovereign is the same way, coins cant be disced out.

why do I like this feature? on the tejon, I set my first disc on small iron, just enough to knock out a bread tie or similiar. the second disc I put all the way up. so when I get a target, I push the trigger , if the target stays its a coin and I move on. I know I miss some silver rings this way. works for me.

so I would say no, tesoro does this on purpose, so you dont miss coins unless you want to.

do you know if the tejon will "lose" depth with the discriminator set up that way?
thanks!

The depth is based on the sensitivity setting, not the discrimination.

So, on some Tesoro detectors(even the Vaquero and Tejon), at full(fully clockwise) discrimination, copper pennies still respond. That is something I wanted to know and also answers my question. My Musketeer Advantage is the same.

But on my X-Terra 70 with the stock concentric 7.5 kHz coil, I can completely discriminate out copper pennies but still pick up quarters and above. I use this feature sometimes in places with lots of copper pennies I do not want to dig that are also very trash infested. I know I will lose silver dimes and older pennies, but can still pick up quarters and above. Now I know some Tesoro's cannot do this. Can a Cortes do this?? Thanks!

Just tried my Toltec II. I will knock out copper pennies at a disc. setting of 8 1/2. Settings go too 10. I consider the Toltec II one of the best Tesoros ever made.

Thanks for all the answers ...... it appears that my brothers Silver is no different than any other Tesoro as far as the descrimination goes .... I do understand the range where gold is pressent , and other items also .....I was just checking te accuracy of the descrimination ....It's not what I expected , and it is what it is .....It appears that the machine excels in desciminating Iron very well, but when it comes to descriminating other targets like Nickels, Pennies, etc , it does not desciminate as well unless the Sensitivity is way down which kinda defeats the purpose ..... Like my buddy told me when I was discussing Tesoro's with him " Pretty much unless you get a Tesoro with a meter on it , you are basically dealing with a beep and dig machine " ...... Thanks again for the help ....Jim

i don't use a tesoro but have used several other brands and if you can disc. out aluminum nickles should be gone also. the sensitivity shouldn't have any effect on the discrimination, just on how stable and how deep the machine will be.

 

[synthnut]

On my brothers Tesoro uMax , if you are trying to descriminate a nickel, and your sensitivity is too high , it will still sound off .....Turning down the sens. will soften the sound a bit more since it's not reading it as much as when the sens is up ..... About the ONLY thing that I can descrim WELL on the Tesoro Silver uMax is Iron .... Everything else still comes thru to some degree ....It's never completely eliminated .....Actually if it werent for the iron descriminating as well as it does , I would probably just hunt in All Metal .....Jim

BTW , the Tesoro does not operate like other brands ....... It's a much more simple beep and dig machine ....

 

[chuck ky]

there must be something wrong with his machine. every machine that i have used with disc. nickles go out before aluminum. if they had a meter you could find some nickles by the needle location or the number but once you passed the aluminum nickles were completely gone.

The depth is based on the sensitivity setting, not the discrimination.

Discrimination is a filter function and filters have slopes in their responses. Even if it is all done digitally, post receive signal digitization, the algorithms still do not present perfect square edged filters.

Do an air test with a nickle. Set the discriminator right where you start to loose the nickle, then back it off just a little so you get a good tone at an inch, now see how deep you can see it. Then turn the discriminator to accept all and see how deep you can see the nickle. Keep the sensitivity the same throughout. The results may surprise you.

On my Vaquero zinc pennies disc out a little bit before full disc. Copper pennies will still respond well but have a very slight crackle in the signal, silver holds true all the way.

my silver umax will disc out a silver coin at full disc setting. it won't make a sound on a silver coin until i'm just above the zinc penny setting. do i need to send it back to tesoro for calibration? i always hunt with the disc around foil, but it seems a silver coin wouldn't disc out even at max setting. any ideas ?..................roger

First you say it will disc out a silver coin...then you say it wouldn't....which is it?

My silver will not disc out a silver coin on max disc....nor would I want it to. I Might just be misunderstanding what you are saying.

my Deleon will disc. out nickels all the time at just a tad above nickle on the dial, zinc pennys will disc out about 98% of the time, every once in a while one will sneak thru. not sure about the Cibola yet, just got it.

On my Vaquero zinc pennies disc out a little bit before full disc. Copper pennies will still respond well but have a very slight crackle in the signal, silver holds true all the way.

The ideal analog discrimination for me is to be able to knock out copper pennies but still be able to pick up silver quarters.
