In Feb. of 18 when they first came out I got an Equinox 800. Coming from an Etrac one of the first things I noticed was its inability to distinguish a penny from a dime. I was used to spot on ID from the Etrac. It took a little getting used to. Got the 900 in Dec. 22 and thought maybe with its expanded ID range that would help. Silly me, it just seemed to exaggerate the issue. Luckily for me in my soil the silver almost always will ring in high and stay within 3 numbers. The 800 silver dimes rang the high 30s, the 900 high 90s and now the Legend in the 50s. And a deep memorial or wheat will also do the same. I will say the ID and stability is a little better on the Legend than the 900. It seems penny-dime ID run too close together on all of the SMF machines. I just chalk it up to one of the characteristics of SMF technology. Although I've never owned a D ll, from what I've seen its no better than any others separating th penny-dime ID.
One tell-tale that I used on both Equinox's was when it was up averaging I would massage the signal until the numbers dropped down, if it was a penny to their respective air test numbers. Just my thoughts.
One more thing, I sure miss that silver warble from the Etrac. When you got it--ya just knew. Good luck. Mark
