Omega And Noise

Has anyone noticed if their Omega is any quieter using the DD coils compared to the stock concentric?

RonK
 
ronk!! this is an outstanding question! i would be interested in
any feedback as well!

(h.h.!)

Yes that's a good question and to tell the truth I never noticed cause I like to run it to it's max and deal with a little noise with each coil. I like to have the extra noise it keeps me from nodding out and doing a zombie shuffle. Happy Trails, Woodstock
 
I thought maybe it was a shielding problem in the cable and then again,the Gamma doesn't have that problem with the same frequency as the Omega.Maybe the Omega is a just a little hotter than the Gamma at lower sensitivity settings.Of course others have posted that they get the same depth with their Gamma. Maybe it's a value of an internal component that differs than the Omega.Who Knows?! I use to Put up with the noise of the 1266 but got rid of it because I never got the depth with it that others claimed and it also fell in love with iron at first site! It just wouldn't behave and stop chasing iron!

Your mileage may vary......but I find that the Omega 11" DD is the most sensitive coil.......to EMI/mineralization.........and also requires the lowest sensitivity to maintain stability. This is to be expected as the 11" has the most surface area of the 3 available coils, thus would pick up the most EMI and also process a larger volume of ground mineralization. My soil is 3 bar.......moderately high mineralization.......IDAHO mining areas (mineralization)/large urban areas (EMI).
 
thanks for the experienced info!..this is what you don't want! (e.m.i) especially in an "urban" coin hunting environment!
not trying to be a "smart a**,but i suspected the dd would be more prone to (e.m.i.) for the reasons given!
just guessing,but i would venture to say,the 10' concentric is considered the "stock" coil for that reason (less affected by e.m.i.)
love the design of the concentric,being an "elliptical" design,maybe covers more ground in a sweep
with a "reduced" cone effect?..just sayin'

J.T. has it right. Guru Monte prefers the stock concentric for his urban hunting in the Portland, OR area. That's about the best endorsement I can come up with....lol
 
you got that right! if monte berry endorses it,
then it's "in the bank" so to speak!..he also loves the
"hockey puck" 5 permanently mounted on the g-2,a "knock it outta the park"
combo!..just sayin'

You guys are going to make me start paying closer attention, because I am of the mind set that the 11" dd ran quieter then the 10" on a couple of spots I hunt that have some emi issues. Hmmmmm! HH jim tn
 
That's why I said your mileage may vary..........Jim gets different results in his area than mine..........the acid test is always the results one gets, where one is detecting.
 
It's a little off topic.........but I think variances in individual coils may factor into EMI / depth variances that different users experience. For example, Monte did a air test of his Omega with a quarter, dime, nickle & penny. He tested the 3 available coils. I replicated his exact settings and here are my results. On the stock concentric and the 5" DD, I got approximately 1" less depth than Monte. However, on the 11" DD, I got 1 1/2" - 2" more depth than Monte. These differences were exhibted on each coin, not certain coins. Same exact machine settings. Go figure...lol
Also, in the field, ground mineralization should to be considered. I don't know Jim TN level of mineralization, but I am a few hundred miles from Monte, yet our soil type is similar (high mineralization) in the Pacific Northwest (Oregon & Idaho). And like Monte, my little 5" DD is the quietest of the 3 coils and can take the highest sensitivity settings before getting chattery.
 
I can deal with the chattering as long as the performance stays hot. Snap-Crackle-Pop is not a big deal for me...When my machine gets to quite I begin to think somethings wrong with it. HH, Woodstock
 
TerraDigger: I will agree with you when it comes to variances in search coils, and even differences from one particular model to another, even if from the same manufacturing run. Going back to when I first started being a new detector dealer in early 1977 (I'm not a new detector dealer right now, by the way) I would evaluate my own personal-use model(s) against new ones I ordered in.

If I found a new model worked better than the one I used, mine became a 'used trade-in' and the new and better-working specimen became my main-use detector. If it was only a search coil difference that improved performance, i ended up with the new coil mounted on my detector. I have seen little differences from manufacturer to manufacturer to include Garrett, Teknetics, Fisher, White's Compass and others, but the biggest fluctuations I ever encountered came from Tesoro.

I think most of thier differences were a combination of BOTH the detector design and the coil design. With other brands I have noted a bit more variance mainly in sampling different search coils.

Also, the 5" DD coil is terrific and much quieter than the larger coils, but that is usually the case.

Woodstock: I am with you on this one. I prefer to hear an audio or at least fork "on the fringe of stability" and it doesn't bother me ... usually.

Monte
 
Monte, Great reply and I see that there is only five years that separate us from when we started detecting. And 95% of the time I run on the "edge" of being stable ( just ask my wife ..LoL ) But seriously, I've put up with "chatter box" detectors and always tune them hot. And I believe I know what you met by the biggest fluctuations came from Tesoro if you met that some a "hot" and so are "not" and that means both their machines and coils. I owned a second run Silver Sabre and that came to me in 1983 that was a super machine, but I didn't find another match for it from Tesoro till the resent Tejon I owned and I've had many Tesoros in between. I had the very same experience with the Fisher 1200 series when my 1220 kept kicking my 1260 and 1265's butt in the field. I was never a dealer but I've had over 40 detectors this past 30 years and the ones I could run as hot as "Scotty" on "Star Trek" were the ones that were the best..."I given her all she's got Captain and if I give her anymore she's going to blow"....LoL! Happy Hunting, Woodstock
 
"Live long and prosper" TerraDigger and "Live long and prosper " to all. Now "Beem me up Scotty, there's no place to detect down here"....LoL! HH, Woodstock
 
yeah! it's unfortunate! "scotty" finally did get beamed up!
just sayin'
