I wasn't going to post them as it would appear that I'm being too negative. The ones I noticed as I found them. On assembly of my particular unit, the upper shaft was way too tight to fit into the control housing section. I had loosened it off, yet it took a fair amount of force to push it in. When it went in suddenly, it took some of the tip of my thumb off. (Most unpleasant). The speaker is ridiculously loud. I hate using headphones. I put a couple of layers of gaffer tape over the speaker, but I think it needs another layer. The multi tones only suite US coins. Our modern Aussie coins all come in the pull tab to screw cap range, which effectively turns it into a single tone machine. I'm a bit concerned with the hand grip. In the hour I used it in the back yard, I found that I was holding it tighter than I should which seemed to cause some fatigue. I'll have to keep reminding myself to loosen my grip. I think that it may be the angle of the grip that causes me to grip too hard. The notches are too wide to be any good. In particular, the pull tab notch. On most other machines, if I notch out pull tabs, I mostly loose only 10c pieces and can loose 5c pieces. With the Omega, I loose 5, 10, and 20c pieces. The detector overloads too easily, which can be irritating.
On the up side; I really like the auto tune mode for it's modulation. This can help to compensate for the lack of tones. I like the elliptical coil and the pinpoint mode. I believe that there are some really good prospects there to get the detector to talk to you about your targets. It seems to have the ability to feel around targets as well as using the overload feature to help sort out some shallow targets. Actually, the overload feature in disc mode may be useful at sorting out some surface targets. It goes off on our larger coins that may have junk targets that are smaller that are on the same numbers, while the reverse is often true of some of our other coins. The detector looked really sharp when I first pulled it out of the box.
It won't be till I've put some time on it out in the field that I'll know whether I'm going to like it or not. If I had been able to go to a shop and play around with it first, I probably wouldn't have bought it, however, I have so I'll get to know it and form an opinion of it down the track.
