Lotsa good info already shared with you so far. I do have and use both detectors,......well actually I have the GB with both DD coils instead of the G-2. I also have all the available Frat Boy coils. In a nutshell, I'd recommend the Omega for what YOU say you want a detector to do. Yes, the GB's/G-2's is "easier" to run slightly more stable than the Omega but the Omega (as well as any detector, IMO) can AND SHOULD be throttled back as needed in order to get stable operation without worrying about what that actual setting may be. A lot of folks really struggle in their minds about what they might be missing with lower sensitivity settings, but my experience at sites that I've spent a ton of time running anywhere from hotter than hades to sensible stable levels, less is many times actually more. Achievable depth with lower sensitivity settings is still substantial and as such and more importantly, one is taking away some of iron's ability to mask. The Omega has the ability to run with four different target tones compared to the 2 tone vari-break of the G-2. Although this difference isn't critical in finding desired targets, the four tones will afford you less time spent looking at the display as you hunt. Keep in mind that the high tone of the Omega is (pre-set) modulated, so good hearing and adequate headphones come in to play in order to get the deep high conductors. The more one can and does change things up in their hunting approach(s), the better the chance more finds will come to light. Although the Gold machines MIGHT run well with particular examples of concentric coils, there is no guarantee of that, as per the manufacturer, whereas the Omega is designed to run with both designs of coils. In fact, I'd recommend the Omega with the three coil package if you can swing the bucks. Don't get me wrong, I really love the GB and am confident and comfortable in using it as a coin shooter, but again, if I'm reading your request correctly, the Omega will better fit the bill for you.
