I just got back from DIV 40 and used the Equinox 600. Mind you I am not proficient with the detector yet, I've used it about 40 hours but I still feel like there's a lot to be learned. In addition to the Equinox I took my GPX. I used the Equinox for a total of about 8 hours in the three days I was there. I did find some good stuff with the Equinox which included an Eagle coat button, minie ball and a New York coat button. For me I found that the Equinox ran quietest using the beach mode in five tones iron bias one, recovery 3 (equal to 6 on the 800) and everything notched out up to 5. You definitely need to GB in that soil. I tried tracking GB and it ran OK but auto GB worked better in my opinion. It accurately ID'd a Target to about 5 inches but had a real hard time with low conductors in that soil. With the adjustments the 800 offers you might get better results. At one point I buried a nickel at 6 inches in one of the fields and could not get it with the Equinox, the GPX easily picked it up. Overall I thought the detector performed well and was very helpful in the iron infested areas. I know there were other Equinoxes there and some good stuff was found by those using them. I know of at least 1 breast plate found with the Equinox. I wish I had a few more days to play around with it in that soil so I could get it dialed in. I saw some other reports on Facebook and some people were doing really well and said the machine ran really good. One guy claimed he found a bullet at 9 inches deep. Others were having a difficult time with the Equinox in the hot spoil. I feel like I was somewhere in between, got decent depth but felt it could be better. I can see an 800 in my future for the extra features in offers.
