Equinox 600 MultiIQ frequencies?

In the comments of the above YouTube video, some people are saying that the Nox 600 MultiIQ only uses 3 frequencies (5,10,15) and others say that it uses all 5 frequencies(5,10,15,20,40). Can someone from Minelab give us a definitive answer?

Page 28 of the Equinox users manual. EQ600-Multi, 5kHz, 10 kHz and 15 kHz. EQ800-Multi, 5, 10, 15, 20 & 40 kHz.

I'm not from Minelab but it uses all the frequencies. Anyone who says otherwise is wrong. Go look at the multi iq chart on the Minelab site.

If you want to read the facts just click the banner at the top and it will take you to the official Minelab web site. apparently you tube, face book etc.. are full of.....never mind just click on the banner.
It uses them all in multi.

Good luck with that. ML has been mystifying frequency usage for decades.

Yep shows no 20 and 40 for the 600

Now I am even more confused than I was when I started this thread!! There are 6 replies and 3 say yes and 3 say no??????????????

 

[laplander]

I posted it uses all In multi, 3 in single. Did you look at minelabs web site?

Pine on the 800 you can run all the frequencies as a single vlf mode. The 600 doesn't have 20 and 40 kHz single modes. HOWEVER, in multi frequency it runs all including 20 and 40. I am 100% correct. Notice the 800 had gold mode. The 600 does not. Running in multi frequency both machines run all the frequencies.

Thank you for the clarification!

Thank you for the clarification!

You're welcome. Now go tell everyone you know that the 600 and 800 are horrible gold machines and they should choose another hobby.

This seems to settle the question. Guess it’s always best to read the fine print.

Forgive me(new guy), trying to understand all the capabilities. What would you be targeting if you were running 20 and 40khz in single mode....gold? If so, when running in single mode it basically cuts down the "hits" from other metals? And in multi it hits strong on everything?

From a "general" metal detector perspective.....any frequency will respond to any metal. Some just do it better than others! Higher frequencies provide a more solid response to lower conductive targets. And lower frequencies provide a more solid response to higher conductive targets. From a coin/jewelry/gold hunter's perspective, silver would be considered a high conductor and would respond best to a lower frequency. Whereas gold would be a lower conductive target and responds better to a higher frequency. Multiple frequency implements all of them at once and should maximize your ability to "hear the hit" on all accepted targets. JMHO HH Randy

In my corner of the great state of New England there is no natural gold ...and the only human gold is in parks and swimming holes. As a cellar hole hunter gold doesn't get on my radar. This is the reason I bought the 600...and I have to say my 600 bench tests gold MUCH better than my T2.

Interesting, I did not know that silver was a better conductor than gold.....good stuff...thanks. So, based on this info, how high and how low will the frequency's end up in our future MD's? Is there a limit?

It sure sounds to me that having the ability to "single mode" a multiple range of frequencies is a good thing, but at the same time more work for the user?

 

[Motor7]

Ok another question, Silver tarnishes very easy, so in the ground it ends up with a coating of silver oxide or silver sulfide which is not as conductive. So a higher frequency would be better for tarnished silver?

Don't confuse the ability of a metal to transmit electrons (the traditional conductivity we we think about) with a metals inductance (which is what we refer to as a high or low conductor). Gold is a better conductor, but it can't hold an electrical charge as long as silver, so we call it a low conductor.

Everything in this game is a trade off. Higher freqs work better with lower "conductors", but high freqs can't move through a soil matrix very well. On the other hand the low freqs can get much deeper reach, but we are currently at about the max depths possible and we've been there for a few decades.

The real futures looks to be with discriminating pulse induction, but its not perfected yet.

Jason in Enid is correct.....don't confuse the conductive properties of a metallic object with what is typically referred to as conductivity on a metal detector's target ID.........which is why I began my comments with "From a "general" metal detector perspective".

If you are interested in learning more about how frequency response and TID numbers vary between target types, you might be interested in reading eBook I wrote several years ago entitled Understanding the X-TERRA. Even though it was written for the X-TERRA series, I included a lot of universal detecting information in the book. You can download if free from Minelab's website.
