Well, either seem to be great machines but from what I've read so far there is no depth advantage of the MXT over the M6 on coins/rings. Since I don't care about prospecting and I'd go by VDI #'s for relic hunting I don't see the MXT offering me anything the M6 can't do for what I need. Then again, there are a few curious functions on the MXT that might prove to be of some use to me under the right conditions and there are also mods for sensitivity/audio boost/tones for the MXT that are interesting. I'd like to find out if those are available for the M6.
Out of the box the less tones the MXT has would be a disadvantage to me. I need my tones as I hunt with zero discrimination most of the time. After reading about it the notch function on the MXT doesn't look too good and I mostly use a mental notch on targets to avoid anyway when I want to. I happen to prefer silent search on my QXT over threshold on other Whites I've used. On some machines such as the QXT hunting without a threshold doesn't cost you any depth on deep targets. More important to have the noise reduction OFF feature on the QXT to punch deeper.
Just curious if the M6 lacks any performance on deep coins/rings compared to the MXT because it has it's threshold just turned down internaly or if it's been designed for silent search. Much of that depends of how the machine was designed to run. IE: Hunting with the threshold turned down to nothing on a machine that was designed to have a threshold can cost you depth, but some machines meant to run in silent search are designed to compensate for that.
Either way, I'm still leaning towards the M6 as my next addition to my line up but could be convinced that the MXT is a better choice for me. The mods alone make it real interesting. I'd still like to hear more opinions on the depth of both machines for coins/rings in normal discrimination mode, or if anybody has found any other MXT function to be of great use for rings/coins that the M6 doesn't offer? Thus far what I've dug up says they are complete match in depth in discrimination for coins/rings. Any differing opinions on that?
