CZ-3D understanding?

[WV62]

Understanding 2, page 19, figure 7 Search coil detection pattern and the note at the bottom of the page
If you look to the right of the picture it talks about Minimum Depth, Good Depth, and Maximum depth. In all these it gives a disc number setting for all three depth ranges. Which indicates depth lose with higher disc settings.

Now if you go down to the note at the bottom of the page it says, Unlike other metal detectors, the discrimination level has little if any effect on the depth capability of the CZ-3D.
I did some air testing and the CZ-3D does not appear to lose depth as the disc is turned up.

Hoping somebody can shed so light on this area.

Ron,

Correct...the CZ does not lose hardly any depth when increasing the disc level. In reading past posts about this, it appears the disc level is really in the audio, and it's linear. So all it's really doing is blanking out sound/tone ID as the disc level increases.

CZ and the Wilson coin and relic are two units I have used where little or no depth is lost in high disc. Matter of fact got some of my deepest silver coins accepting only the last coin segment and dicing out all the rest..After 20 years of CZ use I find if I am not distracted by all the other tones I can concentrate on the high tone better.
I don't need to accept all the segments to tell the blasted rusty nail from a high coin tones but it didn't come overnight and google Mikes CZ page and it will explain many facets of the CZ...matter of fact should be renamed the CZ Bible...

Dan-Pa,

I have been doing the same thing with another detector you are talking about on the high disc and going for just the silver, I call it silver blasting.
I am interested in how you can tell those rusty nails with the CZ-3D, if that is something you could put into words.
I also printed out the Mikes CZ pages.

Thanks

Dan, along with other long time CZ users, has his ears tuned to the different subtilties of the high tones a CZ provides.

Once you start hitting copper and silver coins at depth and start to remember what they sound like ( it's a really mellow high tone 'ping' as oppoesed to a harsher, louder blast that iron falsing gives off) then you will begin to get it. That's why I state starting off, run at discriminate level 0 so you can hear all the different tones. Then, when you start to learn the differences, can run at higher levels and 'silver blast' for older copper and silver coins.

It's hard to put into words or even video it, and in my years of using the CZ, headphones are a must to distinguish the difference ( may just be my hearing and the fact that I always use headphones, but I don't think I would be able to tell the difference using the speaker. Plus, I mostly use my CZ6a...which doesnt have a speaker !).

So it is a sound thing, I was thinking it may have been like a procedure. I should be able to set that up and get a little bit of a feel for that.
