I've owned a MXT for 2 years now and have not used it much. That is going to change. I went out today and did not find any coins etc, but did find some old stuff. My question is this. I have the standard coil on it but also have the 8x14 DD coil. Which should I use looking for coins? And should I search in Coin/Jewelry mode or Relic? Our soil here is pretty mineralized (Western CO). Thank you for any feedback. Oh, I'm enjoying this forum and learning alot, thanks. RonD
