Questions about Signals with my finds

[Deep1]

I was not able to find anything else in the same hole or area. I double checked it even with my hand held pin pointer.

But, what could have been in the hole which would have caused a lower VDI reading? If there had been something else with it (metal), wouldn't it have read higher?

Also, RobNC above, said, "...the horseshoe button and go pseudo-all metal." Will someone please explain to me about the iron/horse shoe button and when you use it. In the manual it just calls it the "all metal" button and only refers to it on the bottom of page 49.

Thanks

The dime may have been sitting on edge. It will give a different VDI.

I also have a theory but haven't tested it yet but I found some strange "iron" pieces that I can easily discriminate out with my f22 and Whites mx5 that the Equinox hits 18/19 on. So I am really think that the Equinox knows something that the other machines don't and there is maybe high copper or brass content in the rusty iron.
I'm going to sand a few of the samples and run them through a spectrometer and see what the results are. (I'll report back on this maybe in a new thread)

I'd guess the reason the two mentioned units id the pieces of iron better is because they're lower gain units (compared to the EQ).

Agree, what causes falsing off small iron is usually the distorted magnetic field pattern off the end of long thin objects that can emulate a higher conductive round target. But it can also occur due to mixed, discrete composition elements. This is true of targets like bottlecaps which are comprised not of alloys but metal clad like clad coins. On edge or worn clad can fool detectors too with variable TIDs due to the discrete clad layers being exposed to the detector. Would be interested in the spectroscopy results on the samples, but I just consider falsing an occupational hazard that you can sometimes pick up on with other clues such as the audio distortion of the high tone or using the pinpointer function to trace the footprint of the target which can reveal large flat or round iron targets.

OK let me ask another question along with this subject.

I have a chance to go search around an old cabin. It's located in the woods in the Tennessee Smokey mountains, where you have to hike into it. It was built in the mid 1800's, but has been in ruins since about the 1940's. My grandfather was born in this cabin.

As far as I know, no one has ever search the area before.

What setting should I use? Park? Field? 1 or 2?

I do not own a nox but i can tell you i have dug a few silver dimes that rang up very low...Zink penny range. once they were out of the hole they rang up high again. Nothing in the hole with them so i suspect it may have been the position of the dime in conjunction with selected Frequency and Ground mineralization. I dug them because the tone was good.
My advice...get away from relying on VID you will pass up lots of good targets.

I think I'd start a grid with Park 1 in one direction, and then go back over it in Field 2 90 degrees from the first direction, but, don't be afraid to experiment. Each site is different with a variety of ground conditions.
