I don't have a lot of time in yet with the Omega, maybe a dozen hours, but the challenge is fun trying to learn it. Having so many hours in with the F 75, F 75 LTD and a while back with the T 2, the Omega does take some getting used to. I have been running mostly with no disc. d3 tones and sen. quite a bit at 99...when I could. At the higher sen. setting(s), 85 or so and up, is the constant beep, beep, beep, normal. It will tell you when some target is under the coil, but then the beep goes on. I have tried all three coils and really do like the 10" cencentric. I do have concerns about depth, having not dug a coin deeper then 6." And, at 5 and 6," the tone is pretty weak. I also miss the high tone that nickels, tabs and small can slaw give. I am used to digging quite a few nickels. 3" deep nickels do lock on 56 good, but 57 has been small can slaw, so far. No silver with the Omega, yet, but somewhat in fairness to the Omega, about half of my time with it was devoted to hunting a site that has yielded me well over 400 silver coins since June 06, when I retired, and I have pounded it with the 2 F detectors. The Omega on this site did sniff out a watch. It has some sort of design and writing on the face, but due to moisture under the face, I can't tell what the design is or what the writing says. I also dug, of all things, the part of a watch that has the 1-12 numbers on it and it says Rolex, bellini quartz. I couldn't see the Rolex until I got home. I remember, however, where I dug it and the next time I am on the site, I am going to dig all signals around the spot, just to see. All in all, I have dug $3.00 + in clad, 2 wheats and a fairly heavy heart shaped metal. HH jim tn
