Difference between operating kHz freq. between models?

[endo]

Is there a difference between the different operating frequencies associated with the Tesoro models? If so, (A) how big of a difference does this make and (B) how does Tesoro decide which frequency to use with each model? Thanks.

Check out the Tesoro site...all the frequencies are listed on each models info page.

Basically, higher frequency will hit on gold, better...lower on silver.
However, the lower Kh Compadre is an anomaly...it seems to sniff out the more finer gold jewelery better than most other machines.
.

I use a Vaquero, 14.5 Kh...I have found gold, but silver and everything else seems to hit real hard too.
Dedicated gold machines are much higher frequencies than this

Manual ground balance is a must for my mineralized soil, so I think I have the best of all worlds in my Vaquero.

Actually, dedicated gold machines operate between 16-20khz. The Tesoro Lobo SuperTraq operates at 17.8khz, and uses auto ground balancing and tracking. We use the Lobo as our exclusive VLF gold finder at Arizona Gold Adventures in Congress, AZ. - Terry

yea, I was thinking of the 'Specialty" units that are very expensive, not the "regular types.

Of course you are right about this range, and like I said, i have found some pretty small gold rings with my Vaq and it was no problem.


Found this info on a gold detecting site FYI...

Question: What is the deference between low and high frequency in Gold detectors?
Answer: Gold nugget detectors usually operate in between 17:w Khz to 71 Khz range. Many people think that the higher frequency is better to have. But it all depends on the soil conditions. Fist of all, we can change a frequency of a gold detector from (for example) 18 Khz to 90 Khz by changing a Crystal or a Capacitor or an inductor. This can cost less than $1 worth of components. I personally like 17 to 20 Khz range detectors for Gold nuggets. Because, If we go higher than that machine would be so sensitive that will die in black sand. Dealers, usually like to sell 40- 71 Khz detectors because they show a very good air test. On my opinion, Air tests are the worst way of showing the performance of a detector especially if the detector is a gold detector, because a good gold detector is for black sand conditions (not air) to operate. If detector is in 50 or higher frequency range, Signal will bounce easily by black sand, because sensitivity is high and machine thinks of black sand as small nuggets. Here is the catch, It is easy to build a detector in any frequency we wish, but it is very hard to control the effect of minerals in higher range, unless our design has some filters or circuits that can eliminate black sand and mineral response. High freq. cannot go deep because of minerals in the soil(signal will be reflected)thefore we will miss big nuggets but in exchange we will get small nuggets just on the surface. If you are moneywise, then, you like the big nuggets, not the tiny ones. With high freq. you will loose depth in mineralized soil, and you will sweep over many nuggets without detecting them. Think of high and low freq. as 'light' and 'radio'. light is high freq. Radio waves are low freq. ( with respect to light). Light cannot pass though most objects and reach the target, but you can still listen to radio in a submarine. That is the defference.

I've seen this question asked on several forums. IMHO, for most recreational detecting (not prospecting) the different frequencies used on the available machines won't make enough difference for most of us to be able to notice. Whites used something in the 6.5 range for a long time, the newer Prizm series is around 8.6. Most Tesoros are 10 to 14 and a number of different machines currently on the market today are in the 12 - 15 range. They all find coins and jewelry if the coil passes over it. Very possibly a serious test might show a bit of difference on gold versus silver etc. , but I'm thinking most of us wouldn't notice the difference in the field.
My two bits.

Agree!!
