For me, the G2 is better at finding high conductors in iron. That's about the only benefit for me. If you're into gold hunting, it can also kick some butt at finding itty bitty low conductors like gold (but is loved by relic hunters for it's ability to find lead & brass too!).IF I'm primarily a coin hunter, it's the Omega. IF I'm hunting for coins in a super iron infested site, I'd grab the G2.
