Well if it’s not a financial burden. I’d keep both! I don’t know the Omega. Though from what I’ve read, it has some nice and interesting features. The AT Pro I’ve used a few years now. On coins it’s very good. And with the 5x8 coil. It’s impressive at finding targets close to iron. I own seven detectors, 2 for gold and the others are what I call universal machines. Each having it’s own best hunting abilities. The reason I say keep both. The different and unique abilities of each almost warrants keeping both. I hunt many old sites dating back to the early mid 1800’s. Iron infested, aluminum and trash infested and very deep soil turned over sites. The different machines having their own different best abilities allows me to hunt the variety of different and unique sites. I’m presently looking at the Equinox. In hopes it can penetrate the Iron saturated beach I’v been trying to beat for years. It’s next to one of the first shipping ports on Lake Erie. It’s had a great deal of iron ore and other minerals lost into the waters while off loading. I’ve even panned the sands there trying to figure out its secrets. The best way to describe the conditions at this location . Take roughly 60 tons of iron filings , mix them in with the roughly 5 acres of beach sand . Wait 80 yrs, then go detecting. Not counting the normal beach trash,which others and myself have been cleaning up for years. The best I’ve been able to get is 3-5 inch’s on quarters. There has been a good deal of silver pulled from that site, though only as it’s thrown up onto the shore and not had time to sink in to deep. The best I’ve Ever done there was after a freak nor’easter made a 2ft deep cut about 10 ft in. Found 24 quarters an some clad. My Explorer will not do any better. The Equinox just may have what it takes, I’m hoping anyway. So there’s my 3 sense.
