Being new to Tesoro......could some one

[Larry (IL)]

explain to me, or point me in the right direction, what the difference is between ED 120 and ED 180 discrimination. I tried to find the info, but only found references to them with no explanation. Thanks.

Don't know if this will help, This is what I found it's a quote by MONTE off the old Tesoro forum.


Why is the ED-180 better than the ED-120 disc.?
"R-n-R", The Toltec II and Golden Sabre II use the ED-120 discriminate circuit. The Bandido II MM, Silver Sabre MM, SHADOWx2, and basically most of the last generation of Tesoros (Pantera, Silver Sabre II, Sidewinder & Sidewinder MM, Bandido, Bandido II and Bandido MM, etc.) have employed the discriminate circuit referred to as the ED-120.

The Amigo II and a few other models utilize what is referred to as the ED-180.

In simple terms, the "120" or "180" descriptions are in reference to the degree of coverage of the discriminate range. Earlier models, such as the Inca, Eldorado, Toltec-100 and such had what could be described as "D-90", or an acceptance range of about 90 degrees. This allowed the detector to accept targets from silver dollars and such on down to lessor conductive targets in a low-foil category. Certainly the minimum rejection level was well above nail rejection.

Users of these earlier silent-search models were able to "comfortably" search many sites without hearing a lot of trash target signals. Unfortunately, in the very worst conditions, such as nail-strewn town sites or some renovation sites, there was too much rejection even at the minimum setting. Thus masking would occur more easily. Additionally, in the worst ground mineral conditions the discriminate circuit didn't work as well at dealing with the ground mineral signal and passing along the desirable target signals.

With the advent of the ED-120 discrimination circuit, Tesoro made a major advancement in functional discriminate range as the "Expanded Discriminate" (thus ED) range went **lower** in the acceptable range and this allowed models designed with that circuitry to just barely kick out most nails at the "minimum" setting and this gave them better "see through" (a bad term, but well used) in the really trashy sites, especially those with nails and other small iron junk.

The ED-120 circuitry is by far some of the best for the average hunter, and even the advanced detectorist, depending upon what their intended application is.

ED-180 simply refers to a discriminate circuit which has an Expanded range even LOWER than the ED-120, not higher. The LOWER range of adjustment gets the unit down into the ALL METAL acceptance range. Many of the competitors models allow such a low-end of adjustment, such as the White's XLT, 5900/6000's, Classic series, Garrett GTA's and Scorpions, and most certainly the Fisher "X" and CZ series.

For a serious relic hunter or a very serious detectorist who wants to have the added performance of an All Metal motion discriminate mode of operation, these are good units. For relic hunting and other searches where ALL targets are desired, then a broad-range, with a lower-end acceptance (ED-180) discriminate circuit is desirable.

However, most hobbyists are NOT interested in locating all metal targets in an area. Most are recreationalists, serious or casual, who are not that interested in having a primary search mode that will accept all metal targets, preferring to reject annoying nails and some other small, low-conductive targets. Thus, the ED-120 is the most used discriminate circuit concept that is employed by the Tesoro folks. It works well.

In some really bad ground the ED-180 will give you some much improved performance, but in "typical" ground and detecting situations the famous ED-120 should do.

Now, I hope this rambling wasn't too confusing. As for which is the "Better" of the two, I would have to say that I would be content with the ED-120 under most conditions. I do, however, employ the option of going to a lower range (ED-180) when I get into some very mineralized areas where there are NOT a lot of detectable targets and I prefer to get the best depth/performance.

Confuse you? Questions? Just e-mail and I will try to clear it up! Posted By: Monte on the Old Tesoro Forum

Hay Larry,

The terms are used loosely.

Some ED 120's accept a wider range of materials than others.

That's true of the ED 180's also. For instance,

The Vaquero has a narrower acceptance range than the Eldorado.

They are both listed by Tesoro as having an ED 180.

So you can not use the terms to precisely identify each machines

characteristics.

Some machines have strong similarities, but they should each be

evaluated on their own.

Happy Hunting,

Thanks so much guys. That would have been my guess, degrees of rotation on the discrimination knob, just wasn't sure. Thanks again.

I got to play with the Silver uMax again the other night and again, surprised with the depth and simplistic operation. Tesoro has a winner there.

Hey Larry, nice to see you here. I've followed many of your wife's and your postings on the MXT forum. I have an MXT along with a bunch of Tesoros. While the MXTs and DFXs are wondrously capable machines, there is a fun factor with the smaller, lighter Tesoros that they are missing. For a quick grab and hit the tot lots or small parks, I nearly always choose my Silver Sabre umax with a 7 inch coil. .

Yea, "fun factor" describes it well BB. We have a club silver hunt coming up this Saturday and I'm planning on using the Silver for most of it and that's why I'm trying to get some "learn" time in. I get to have some fun this year because this is the first year in many that I have not been the one putting on the hunt. I'm looking forward to playing with my new toy

Thanks for the Kudos.

[size=large]... Larry, if you compare it to an MXT, the MXT has, basically, an ED-180 type Discriminate control because it adjusts (at minimum) low enough to just ignore the ground and still accept ALL metal targets, to include all iron and non-iron.

Some models, such as White's XL Pro, actually have a broader range of adjustment in the Discriminate mode that allows not only acceptance of ALL metal targets, but it goes low enough to adjust to the ground mineralization. Very few models allow that ability today. Most have a little rejection at their minimum setting, often enough to reject some small amount of iron, or even all typical iron (nails) and some very small foil.

The old discrimination designes, as used with early Tesoro's and quite a few manufacturers at the time, would accept the upper 100

Thanks Monte.....now I understand.

Imagine me, asking 110 questions, lol. I love my old bandito!!! Old 90's stuff is good stuff
