Hello everybody ,, have been relic hunting 30 years ,, good ground-hot ground Va Md Wv Nc,, currently own Whites 5900 Whites Blue&Gray Whites 6000 M/l Gpx 4500 Whites Tdi and my latest is the whites Mx sport ( not really crazy about it) considering a 600 or 800 ,, not trying to compare my other units to the nox trying to make a better decision is the nox waterproof coil and control box , is the nox capable of working in hot ground not compared to a pulse but as good or better than any other vlf’s and how’s the depth and is it really that much better or just a lot of new excitement ?? Thanks joe Klecz aka (Confederate Joe 1861-1865)
