If you was to cover that with a fine layer of dirt you would NOT find your dime or quarter with the Equinox.
Mine will.
I live and hunt in massive iron...depth is an issue here but it is for all brands, what our biggest problem here by far is iron masking.
It is insane around here.
Deep South mineralized red clay soil, our state mineral is Hematite, and I have not only naturally occurring iron in my ground but most of my sites had old homes or neighborhoods that were knocked down long ago.
I have taken my Nox into all kinds of areas and it deals with masking better than anything I have used so far.
In a private lawn filled with iron I have been hunting for years, a small patch of ground I have hit hundreds of times with 4 other detectors and many different coils, I brought the Nox in when things went dark for a long time.
It lit up this site, I found coins I never got a peep on before and believe me I have been resorting to digging the most iffiest signals for a long time now so if I got a hint of anything I would have gone after it...but on these I never did.
So far I have found a few more wheaties, a merc dime and a shocking surprise...two silver 50's rosies sitting in the same tiny hole.
It was easy for the Nox, the signals I got over these coins weren't exactly perfect or even super stable, as a matter of fact if I was still brand new to the thing I would have never noticed them but over the last few months I noticed some quick, repeating behavior that I learned can be, and usually are, indicators of non ferrous targets masked by a sea of iron in my devil dirt.
None of these coins were deep, the merc was only a few inches down.
The areas I found them were near sidewalks and curbs, areas I hunt over and over again.
The fact is my other detectors just couldn't see them and the Nox did, or at least gave me a fighting chance to find them after I learned a few helpful things.
This was no fluke, I have done the same thing at many other totally scoured sites, also.
The Nox has made a big difference hunting around here in our iron, I really believe that.
Evidently other s do to because I have 3 other friends I hunt with that own Whites, AT Pro's and Max's and all got a Nox...and haven't picked up any of their other detectors since.
Iron is a problem for everyone but for some of us it is way worse than many can imagine.
If you live in an area like we do you are forced to figure out better ways to do things, it is an ongoing daily process and I had to learn a lot and learn it quick to deal with this place...and I have although I still need to get better.
The key is starting with a tool that can give you an edge of only a little.
For us that live in iron the Nox is the best at it so far.
