MXT Tone Operation Question

[RBnGA]

I'm seriously considering purchasing a MXT. Primary use will be for civil war relic hunting in fairly mineralized soil (N. Ga.). Now for my question: Knowing that each site/soil/object conditions are different roughly on average what depth does the ferrous vs. non-ferrous tone id capability end?
Thanks.

Like you said alot depends on your soil. I assume your asking at what depth does the tone for an object stop? In order to get a VID you have to have a tone. In relic mode the low-iron or the high-good tone. I can account for my soil that can range from average to moderate soil. The identifying tone tends to disapate at abt the 8-9 inch depth. running a little over the preset sens. now thats the audible tone. I have dug bullets and larger flat buttons in the 10-12 range by digging the change in the threashold. the threshold will rise slightly over a deeper target indicating somthing there but it just cannot lock on it. I look at it that if it's that deep its worth the dig.

but in the ground where I generally hunt it wasn't reliable much beyond 4" or so.
