2 issues with the Deus. One is correctable.

I'll start with a clad dime. I just stuck a Dime in the dirt on edge. I was using the 4Khz frequency and '4' reactivity. When swinging the coil lengthwise, the Deus could not see the Dime until the coil was about 2" from it. And even then, it was a high tone, but raspy sounding. Surprisingly, the TID was right on (73)

Secondly, when in the 4Khz mode, a US Dime shows on the TID a 73. The Deus is set up from the factory to sound off on a high tone only those targets which register 76 and above. So US Dimes will sound the same as Nickels. This can be changed in Expert mode.

When you use a lower frequency, the reactivity setting is not as effective, it is more usefull with the higher frequency, like the 12khz and 18khz. When you use 4khz the reactivity should be around 0-2, no more than that.

I will try that. How do you know this?

I believe, it was said in the manual..that the reactivity setting is more usefull, when you use it with the higher frequency. 4khz is naturally a lot slower frequency, than the 12 or 18 khz. Also if you like to find coins on edge, use a higher frequency, because it is more sensitive and thus will be more effective.

I thought the lower frequency was more sensitive to higher conductive coins...

It is effective, when the object is small or on an edge. You should try the 8khz or 12khz with the coin on edge.

I remember reading with the V3i - When set on a lower frequency (2.5kHz) the recovery settings (fast) don't have the same effect. I think it has to do with the wavelength sort of being too long for such a fast recovery speed - they just don't go well together. I don't remember, but it was more a bi-product of low frequencies in general than "the detector".

Maybe someone could jump in here with a background in electronics...

A coin on edge.......... especially longitudinally............ can look like a much lower conductor. The coin can look like 'foil' ..... or (less likely) even iron.

One thing to remember, most detectors are designed and built to ID coin sized targets. A coin on edge has very little surface area to detect and will "trick" the unit into IDing it as something it is not.

According to what I read at XP s site the 4 khz freq and programs is for larger and deeper items ( cache ) and would work best with the large coil.

It was not developed for general detecting and certainly not coins on edge.

Larger civil war artefacts would be the targets to try that on.

Is this fast response...?

Stunning.............. if this is real.

Thanks for the info. I went to a very hammered park today and was killing the Dimes on edge with the 8Khz frequency. No silver but learned a lot.
