So a slight difference between multi frequency of the two detectors you speak of. The box is capable of selectable and simultaneously frequency operations, while the MK is selectable only.
While I have never used either machine yet, I'm thinking the feature of both modes would be the defineing point for me.
I guess I need to do my DD, bc I'm really not following you on the simultaneous feature you're talking about.
Do you mean the different frequencies can be used at the exact same time in different modes?
Yes, the Equinox will shoot all frequencies at the same time or you can selects the frequency you wish to hunt with. On the MK you only have the option to select which frequency you want to hunt in, similar to the Deus.
To expand, the other Minelabs like the CTX, Etrac are FBS, (full band system) that will alternate 28 frequencies but not public knowledge how many at one time. Can't recall the BBS specifics.
Desires the box, the only other machine I think operates either individual or all frequencies simultaneously is whites V3i
