Is the X-terra 50 comparable to the M6?

I don't know the answer to this, but from the reviewing that I did on other forums when I was considering a Minelab Xterra,there were alot of complaints about the Minelab's shutting off/the headphone jack comming loose/the display going blank/the sound quit working/weak battery springs/ Maybe the problems have been fixed. Not trying to knock the Minelab just going by the reviews I have read. Any White's detector is quality built. Steve.

They are comparable but the M6 will work in more situations and has more coil options. Either way you can't go wrong.
