I have and use a MXT Pro, it still is pretty much on top of the vlf pile for coin/jewelry for me, I have tried some of the latest machines and gone back to the MXT Pro every time so far. Most my park finds are in the first 5" of soil, not worried about the latest and greatest, its very good on gold jewelry due to the khz freq, even with the 5.3 eclipse coil I can hit 10" on a coin if needed. The gold mode works well down to about 2 grain wt nugget, is limited in depth due to vlf but is a decent gold machine in some areas. Very wide range of coils makes the MXT very versitile.
