Lowest Frequency Tesoro?

[Canewrap]

Has Tesoro ever made any ultra-low frequency machines, like between 3 and 8khz? I know the Eldorado is 10khz, but is that lowest they've ever made?

Hi Canewrap !

I doubt there are many members here who could answer that question.......maybe Monte V. Berry.

Have you checked the Manuals for all the Earlier Models ? Go here: http://www.tesoro.com/info/manuals/, then scroll down a little ways.

Another option would be to contact : Robert Martensen, robert@tesoro.com, 928-771-2646.

The lowest we made ever is 10Khz

What is the purpose of the low feq? I saw a metal detector that was in the 2.?Khz. I just wondered if that would be able to find gold or coins? I do know that higher freq can detect small gold close to the surface. But what would the advantage be for a low freq? Deeper finds? But will it also find gold deeper?

My 10 khz Golden uMax and my 6 khz Fisher detect gold jewelry and silver coins equally well in air tests. I think maybe at least 20 khz difference would be noticable for gold and silver.

With the exception of higher frequency on machines designed for gold prospecting, I seriously doubt that the general hobbyist will ever notice a measurable difference due to frequency while coin shooting or relic hunting. Just my two bits, but comes from using machines with frequencies from 6 to 14. One can get into theoretical discussions on the pros and cons of lower versus higher frequencies, but I'm of the opinion it isn't a major issue in practical use as there are other differences from detector to detector as well.

What about the fact that lower frequencies handle bad ground better?

The Troy Custom Shadow X2 was either 9.6 or 9.9, if I recall, and were essentially slightly changed Silver Sabre

 

[allcav]

I have the Shadow x2 manual in my hands, the operating freq. is 10 khz

 

[Canewrap]

Hi Monte, thanks for responding. Yeah, I've been wondering if there really is much difference in performance (depth and ID wise) between a machine operating at say 5khz and one operating at 18 khz? I've seen long discussions on the value of using the low end of that range to find silver easier and that the low end handles bad ground better. Is either assertion true in a meaningful way or is it a matter of splitting hairs and most of us wouldn't really notice the difference?

That's from the website and at one time I thought they said it might have been 9.8 or 9.9, but they had two they promoted. Anyway, one was for the "Lady Shadow" (9.6 kHz) and that allowed a guy and gal to each own a Shadow X2, share coils, but be able to hunt close together w/o chatter.

The manuals for the Shadow X2 do list the frequency as 10 khz, but Troy said some were made that ran at 9.6 khz. He called them "Lady Shadows". They came with a Lady Shadow sticker in the box that could be put on the housing and he said they were 9.6 khz so a husband and wife, or two hunting buddies, could hunt close to each other and not experience interference. Whether that's correct or not is open to question, but on his website the specifications for the X2, listed below, have them listed as 9.6 - 10 khz. The specs page is at http://www.troycustomdetectors.com/products/x2specs.html. Since you work for Tesoro you should know, but In any case, whether accurate or not, Troy was the source of the belief that a 9.6 khz X2 was built.

I apologize for duplicating your post. I started typing it before you posted, but the lady of the house had a "honey-do" for me before I finished typing. I finished typing the post after I took care of the chore, but didn't check to see if anyone else had posted the info.
