Your right on GarbageBill with your assessment on the Omega 8000.....I've had one for about a year now and truly love the machine.Yes it has some EMI issues but once you learn how to setup for the area your detecting it works well.
I do the same thing with the Omega,if it's a bit chattery I crank back the sensitivity until it quiets down and then bump it back up until I can still work with it.It all depends where you hunt..most of my areas are in the country and have no EMI issues but if you are hunting in and around power lines or town and city parks or athletic fields my Omega will become a bit chattery and it needs to be turn down a bit.
Hunting country fields,farms and wooded areas I run it at 99 sen and 16 dis.In and around parks or sport fields I run it at 50 to 75 sen and 16 dis depending on EMI issues.
I also have the 5"DD coil and the new 10" DD as well as the "11 DD all coils do well on the Omega but my favorite one would have to be the new 10" DD for a all around coil...it go's deep and gets great separation in iron and pinpoints well.
The 5"DD is deadly on coins and jewelery in spots that you can't use a bigger coil.
I just ordered the 13" Detech DD coil we'll see how it does on the Omega....
For the money the Omega is a great all around mid entry machine and is a does very well on coins down to 8" to 9" in my soil here in Nova Scotia.
I also have a G2 which is a great detector as well and I can interchange the same coils with the Omega.
Good luck in your quest Newfiehunter
I have a gamma which is a step below the omega (I believe) and when I first went out with mine it went berserk and I couldn't tell what was going on. Asked on this site about it and was told to turn down the sensitivity but only to where it got stable then creep it back up until it was as high as it would go without going bonkers. Worked perfect. Haven't had a problem with it again even in my backyard which has more junk buried in it then a landfill!
