Omega 8000 question

[Elton]

What does the 11" DD coil do for the Omega as far as detecting pro's go ??????? ..and what are the negatives ?. As I'm sure there are trade offs...

If I put the one I have on?? Will I start hitting rusty bottle caps like the F75's do ?????.............. and small pieces of iron ??.

I used the 11" DD on my Omega all the time.
It got better depth,
Better separation,
More accurate depth readings,
But! they're is a trade off in the discrimination ability, I'm not going to say bad, but you will probably dig more rusty bottle caps. I never had any real problems with other iron that I don't have with my other machines.
Also, you will probably not be able to run the sensitivity as high with the 11" and you can with the 10".

I sorta figured it might hit the rusty caps with the DD ..WOW more depth hu..This version 6 has plenty of depth with the 10" coil and rock solid operation. Maybe I can get a couple inches more with the 11"

I'm easily hitting 7" dimes at 70% sens with the 10" and the depth reading is better than any T2 I have ever used for accuracy. It's just about spot on in the readings.

I'm really liking this Omega and will give the 11" coil a shot..I might even buy a 5" coil for really junky places though the 10" isn't that bad in most areas since it's so narrow.

I had two of the 5" round coils for mine, I passed them both on pretty quick. I didn't like them at all!,

Looking down the shaft at that tiny coil and viewing that big wide open space..It sure looks tiny doesn't it... I would rather cover more space and lose a couple targets myself..

Myself I have only ever used a 5" in a limited space area of not much more than 10' area..

Years ago my brother Ron used a Fisher 1265 and one of his favorite coils was that little 3-3/4" coil, he did good with it. Well moving up to modern times and now discontinued models I ended up with a 1266 (I still have it) and a deal came along for me on one of those tiny coils, when I got it and mounted it up as I looked at the hockey puck almost a coil I thought, "the only thing this would be good for is hunting flower pots" and so I nick named it my flower pot coil. It worked good, but I couldn't use it in any open area at all, trying to overlap coil sweeps wasn't possible, and if you did your forever hunting a 5 foot square.
Now, as far as the 5" round Omega coil I could hunt the open areas with it, but the two I had for my Omega they're was just to much performance loss as compared to any of the other coils, like a dime slightly tilted and its just gone at like four inches. On my first 5" coil I just thought it wasn't very well tuned for my Omega, but later on when I gtt a second one I found the same limitations. Now, one thing that probably hurt me was I had started off so well with the 11" DD and I ran it so much that I wasn't able to jump back to the little 5" coil.

The last temptation I had before I sold my Omega was I wanted to try one of the newer 5"X 10" solid DD coils, its very possible that that coil might be the best of both worlds, the separation of the 5" and the depth the 11" and the ground coverage of the 10" concentric. I never got to try one, but in my mind I had thought that I may have been able to just mount that ONE coil up and sell off the rest, but I never got the chance???

So far my favorite coil for the Omega is the Sharpshooter. I haven't had a chance to try 10 inch elliptical coil on my new quieter version Omega. I got one, but I haven't gotten around to using it yet out in the field. I was using the Omega yesterday and it was running super quiet and finding plenty of coins, but when I crossed the street it started chattering and didn't preform well at finding good targets. I had to put it back into the car and get out my Tesoro Cibola. Then I started digging a lots of coins. The Omega is a great machine and the newer versions run a whole lot quieter, but it wouldn't hurt to have a Cibola or Vaquero with you as a back-up for those really difficult situations that you might run into from time to time.

I'm sure that is good advice Tabman ..............Have to be something else though as back up..I am not a Tesoro fan ..

That's an Idea !! Thanks

11" DD will get you and inch more on a dime and 2" more on a quarter. It will bring in more EMI though. You gain 2" of coverage as well. I'd is not as good on rusty caps and screw caps. The rusty's will drop in id when lifting coil. the screw caps and similar sized aluminum do become a nuisance. The Omega does well ignoring small iron, partly due to lower frequency. Only high tones i've gotten on iron is big iron. And now the new version will still throw in a grunt or two when you get big iron high tone.

I've used the 11" DD Biaxial, the stock 10" concentric, and the 5x10" Elliptical DD coil on my Omega.

The concentric was quietest in EMI, and rejected the bottle caps well and had the BEST ID accuracy. But in my red clay, the depth wasn't as good as either DD coil. But still very decent.

The Biaxial was the deepest, but only very very slightly compared to the 5x10. Also gave the most EMI chatter by a large margin. Worst ID accuracy of the three, as stated it was fooled by bottlecaps everytime. But as stated, raising the coil usually gave it away. If I was relic hunting in fields, this would be my pick.

The 5x10 is my favorite coil. It gets almost the same depth as the Biaxial, but IDs better and doesn't go nuts on bottlecaps as bad. Seems more sensitive to tiny stuff, especially aluminum, but it IDs as aluminum/tabs. EMI noise is about the same as the concentric, which is very little. I like the solid design, as it doesnt snag. Far and above my favorite coil so far. I actually traded all the others and only have the 5x10 now. For my hunting, (deep woods and homesites with some older park use) it serves me well. In my opinion, it is the best of both worlds.

BUT!
Pinpointing with the 5x10 sucks compared to the other two. You have to pinpoint off the tip, whereas the others pinpoint in the center like a normal circular concentric. Your depth reading is still usually pretty accurate though, oddly enough. It's just a little harder to find right where the target is. The deeper the target, the harder it is. But after a little practice I can keep about the same plug size as with the others. It just takes more work.

I hope to add a small coil for really trashy spots here soon. I'm torn between the Teknetics 5" DD and the NEL Sharp. Unless I can find a good deal used for an OEM coil, I'll probably try the NEL.

I've been thoroughly impressed with my Omega. It's a version 5, and I bought it used.

Each of the coils mentioned are good and have their place. For me, though, the 5 x 10 DD probably saw the most use. It is not quite as laser like as the 5", but is very good, will get 7 & 8" deep coins and is lighter then the Sharpshooter, as one after market example. HH jim tn

I mainly use the 5x10 eliptical concentric coil...I find I get good depth, good discrimination (although sometimes you need to dig those deeper targets with jumpy numbers). I aminly use the 11" DD coil at the beach where I am hunting in all metal anyway. Horses for courses, and they're mine.

This video I did is showing how to pinpoint with a 5 x 10 DD search coil and how slowly you should work a search coil. Just watch the orange dot that I placed in the center of the search coil. The target will be exactly under the orange dot. I can pinpoint dead on in the disc mode. I can also do the same thing with the Omega using the NEL Sharpshooter DD coil and the the Teknetics 5x10 DD coil. You just need to turn the search coil at a slight angle and rock it back and forth.

What kind of depth do you guys get air testing a quarter with your 8000s?
