I had a Equinox 800 and damn it was good. But had a dilema come up and needed some instant cash. So it was my 5000 or 800. No contest as I like the 5000 almost as much as my misses :lol:
But seriously, have had Terras, Sovs and an MXT but that EQ was pretty special. Never had a disc macine separate trash from treasure like it did once I got to know it. Very very good at it. Got gold with it too, but in quiet ground. Yep it was little stuff but it did find it when I didbt expect it too. But also wont lie, my 5000 in the same ground using an Evo on high sens settings after finding stuff with the EQX found things, gold, the Nox obviously couldn't, but still the Nox really impressed me. If right now I needed another machine to complement my 5000 id get another Nox 800 in the blink of an eye.
Now though I detect as a fun hobby and have no inclination to get anything else.
Hope that helps.
