MXT past 5 years

[DoomDrag]

I don't know where to really place this topic so if its in the wrong place please forgive me.
I was wondering what changes has the White's MXT E-Series metal detector gone threw for the past 5 years, if any? Anything far as performance? Major or minor?

You might try the white's board. May get more responces on there.
