Here's my review on the M6.
My favorite trash hunter !!
Opinions on a particular detector can vary from a piece of crap to the best thing since sliced bread and somewhere in the middle is reality. I like to find the strength of a detector and decide if it fills a niche better than one i have and the M6 for me is best for hunting trashy sites. Don't really care about notching and prefer to use Tone ID and listen to everything. Threshold nulls are useless in my opinion at very trashy sites so silent search is OK for me. The best thing in my opinion about the M6 is the plethora of accessory coils along with the quick reset recovery speed, tone id, and the Meter which helps when cherry picking or attempting to sort through the mess. The 6"x10" DD Eclipse is my primary depth and coverage coil and deepest coin has been a wheat penny at 7". My favorite small coils are the 4.5"x7" and 5" EXcelerator's The little 5" EXcelerator hooked up to an M6 is awesome using tone id and no discrimination. Had some nice coin, jewelry and a few relic finds so far with a well conditioned 1866 2cent piece less than 2" deep being the best so far that many other detectors had to run over. It's hard to explain but avid trash hunters should understand tone variance and that's the strength of the M6 along with the excellent small coil selections. The M6 would make a very good primary use detector when hunting coins and jewelry and for some relic hunting but love it at trashy sites. I'd rate the M6 at 4.5 because it does lack threshold, true all metal search mode and manual ground balance although the auto GB circuit works excellent. I guess i said my piece and hope others will confirm or dispute my opinions. HH Bill
