Any truth to the Newer or later Omegas being quieter?

I'm surprised nobody has tackled this question yet?

I couldn't tell you the difference because I've never ran an older one?
But, I'm thinking a lot of the noise problems are from people that are trying to run the sensitivity above 70 as which the manual states the machine will become noisy at that point and that it takes the more experienced user to run it into the "Noise".

So far I've kept mine just below 70 (65-69) and its been fine, its also pretty deep at that point, I know its hitting coins in the 8" deep range and doing pretty good at ID'in them too.

The sensitivity has two ranges. From 0 to 70, the sensitivity increases
on a linear scale. Above 71, the sensitivity threshold level starts
changing. At values greater than 70, some internal circuit noise will be
noticed. The higher the number, the higher this background

New and old how do you know what is what?

Mine shows a 04 when I turn it on with the pin point button held, so is it an old one or a new one, has the black lines not the red lines.
Mark makes a great point here, how much nosie do you want to deal with? if your going to run it with the Sens. at 99 yeah you will be working into the higher noise level.
I got my Omega from Monte and he gave me some real keys points on how to deal with EMI, you want to know how to run the Omega or any other detector that would be the guy to ask.
Discm. also plays a big part in how much noise you will deal with, if your hunting a high trash area and run the Discm. at 1 you will deal with alot of noise, some guys can do it and they do real good, Im not one of those guys, to much noise and I start loosing good targets, but everyone hears things different.
The problem seems to be that everyone wants to run the Sens. at max, they feel its the only way to hit the deep targets, problems is in some areas you run it at max and you wont find anything,

Thanks

I rarely run into EMI issues. 04 version with black lines. although I don't see any shielding on the inside. EMI is mostly coming in through the coil head anyway.

Underground fence is by far the worst. buried power lines close by and/or transformer boxes.

99% of audible emi in disc is in the sub zinc range so with some disc you can run it hot and eliminate audible EMI but it's still there and will affect performance negatively but the disc will not.

First Texas lets you run most detectors hot which some give a negative rap for being noisy. If you understand how the detector is set up properly then you will love having the option. I'd rather have the option than be stuck at 75% gain or not threshold increase.

I can run my omega at most sites 11" DD at 81 with some occasional noise and 5" dd around 91. I rarely see a benefit of 99 unless it's a really deap target and I'm trying to ID a little better. For that I may switch to 99, d2 tones, or all metal to get that extra 1/2".

I believe the first Omega's only had one headphone jack, the ladder models included both 1/8" and 1/4" headphone jacks.

I run my Omega at 99 very often. It chatters a lot when sitting still, but when I sweep the coil it runs nice and quiet. In higher EMI environments running around 70 seems to work fine. I have noticed that with the 5 inch DD coil I can run it very hot almost anywhere. The Omega has been very good to me, landing me some 8 plus inch silver quite a few times. It sure seems hard to beat

My Omega has the two jacks and works well for me, I just got a pair of Gray Ghost headphones from Big Boy Hobbies, there great and they have the switch on the side, if my Omega gets to loud when Im digging a target I just flip the switch down and it shuts the sound off.
Im still hoping to hit that deep 8" coin but I guess I just havent passed the coil over it yet.

If that's a volume limiter switch you can run in switched on all the time without any loss of faint or lower audio responses. The limiter only put a ceiling on over the top volume responses.
Or that's how it is on the Sun-Ray Pro Golds.

From what Bart at Big Boy Hobbies told me its for different machines, I need to ask him about it again but when I flip the switch I hear nothing at no matter what I swing the coil over. When Im done digging my target I just flip the switch up and the sound is back works great for me.

Well if that's what it is then the audio won't work at all in one position.
If its a limiter switch then with it turned on the volume just can't get as loud.

My Sun-Ray golds have two switches, one for detector types and the other is the limiter on or off.

Never used a sun-ray before but I hear there great, and your right its a limiter switch one way turns the sound off the other way turns it on, the headphones have a volume control dial so you set it where you like it.

It still doesn't sound like what I'm talking about.

The Sun-Rays have,
Dual Volume control knobs for adjusting the volume.

Two toggle switches,
(1) detector type, if you plug them in to your detector and you get No sound, flip the switch to the other detector option.
(2) Volume "Limiter"


For explaining the volume limiter switch let me use some bogus numbers just for an example.

Lets say with the limiter OFF you get a good 30db of volume on deep targets, but on surface targets you get a 120db of volume which is to loud, you like the soft faint volume of the deeper targets but you don't like the over the top of the shallow targets. In this case you can flip the limiter ON! now what you have is the deep faint targets still have the same nice 30db of volume, but the shallow targets volume will be controlled by the limiter so they now only produce an 80db of volume, even a storm drain cover LoL

The limiter doesn't turn the volume on or off, it just clips it off at a certain MAX volume without effecting the lower end of the volume range.

If you try to adjust the above problem with only the volume controls then you end up lowering or raising ALL target responses deep and shallow, when this happens the really deeper target responses may fall off in volume to the point that you audibly don't hear them at all.

I'm I making any sense?

Now let me toss in another curve ball into this,
Some detectors have what is called "Modulated Audio" this is one that a coin at 8" deep will have a distant fainter volume report than the same coin at 2" deep. In the above 30db vs 120db the detector would be one that has "Modulated Audio" and in this case is where headphones with a volume limiter can really help.

Then you have detectors that Do Not have "Modulated Audio" what these do is any target that is detected sound off with the same volume level, deep doesn't sound any different than shallow. With these detectors a volume limiter isn't necessary because the volume can be control by just the volume control.

The Omega's have great "Modulated Audio"

I looked it up at Gray Ghost head phones, it says, selector switch for single output, it only has one volume control dial, not sure what all that means its my first pair of Gray Ghost head phones, Bart at Big Boy Hobbies said they work well and so far I have complaints.
