from you answer is that the detectors are very coil dependent .Reactive and resisitive overload is coil dependent and the detectivity (sens) is coil dependent.Very good info and goes with what I knew the first time I picked up the T-2 .The Bi-axial coil was making the machine perform like no other in separation and target depth and the same time!
When I put the Bi-axial on the Omega it was like night and day difference in performance again coil performance.
Yes the ergonomics of your detectors are the best I've swung but I must say you have out done your self with the Omega. removing the battery box and additional circuit from under the elbow and just going to one 9-volt is way better. I hope the newer detectors will be built on this type setup plus it has to be easier to assemble.Plus I like the knobs for the disc and sens they are the ones I fiddle with the most!
I know you cant incorporate everything in to a detector it would be impossible but if you could get the T-2 to give us the option of "relic mode" all metal and disc running together with 2 tone mode to set the audio break point (lo/hi tone) on the disc dial like the MXT does instead of 0-40 being ferrous and 40-99 being non ferrous it would help us relic hunters (and I know Jewelry hunters ) alot when dealing with funky house site dirt in the co-located nail and low conductor(I.E. Buttons) mixed together. these signals are hard even with fast recovery machines.I know I can use 1 tone and eliminate targets but relic hunting you need to know where the iron is to slow down and explore if I silence the nails I would walk right through a spot and never know it existed .(believe me I've done it with other machines)
It would also help dig some of the iron relics we relic hunters love like gun parts (butt plates ,lock plates trigger guards,bayonets Etc.Etc.
Again thanks for answering my questions You are the only engineer I know of that would go out of his way to answer a customers inquiry!
That means alot to me and I'm sure others.
Thanks

It would be interesting to see an updated specification chart on the Omega 8000 with the 11" DD (I assume this chart is on the stock concentric coil).
Tom D. commented about it's fast speed, and I agree it's fast, but I know it'll be even faster yet with the DD. Keith I ran it in disc 0, and I was able to hear iron gruntin' away. This has been posted here before with Tom's permission, I'm sure Keith's already seen this info, but for those that haven't, it's worth reading (notice the comment about some elongated Fe targets are completely undetectable in ID mode):
* Disc '16' is the critical/pinnacle for max unmasking capabilities for the Omega..... as '21' is for the T2.... and '6' is for F75
* Fairly heavy EMI mitigated by sweeping coil in concert w/freq change
* Slightly better depth on high conductors vs. T2
* Slightly less depth on low conductors vs. T2
* Pinpoint delay is disconcerting..... for the first few moments of usage.
* Some elongated Fe targets are completely undetectable in ID mode with
no Disc & no notch. 90Deg turn...and Fe is then detectable. Undetermined (at this point) if this is a attribute...... or detriment.
* At first, the MP clock speed appears to be slow...... but Omega would
target-separate as well as T2
* MOST IMPORTANT: Omega is the industry forerunner for "stability"...
and the industry forerunner for "confidence" in Fe/iron nail infested areas. Although the unit is not as sensitive/deep as flagship F75..... this fatigueless
operating characteristic in iron is surreal. It is a dramatic departure from all others.

Responding to Keith, Cal, and [implicitly] another person who was quoted in a post:
Keith, some of the things you said in a very recent post..... well, suffice it to say that , hmmm, ....... remember when you were a kid and put something on your Dear Santa wish list? You often got what you wanted but often in a form different from what you had imagined it. ......Someone (won't name any names) suggested in another thread that I shouldn't be wasting my time reading forums. Then there's that other complaint that we don't pay any attention and don't listen! The parable of the flutes and dirges all over again 2,000 years later. Suffice it to say that we do listen, but can't always deliver what customers want because there's about a million different customer wants, but only about 4 engineers to deliver those wants, and the only wants the company will pay us to deliver are the ones that marketing dept. thinks will make money. .........I occasionally get phone calls or emails from inventors who want to sell us a great idea. I have to explain to them that we are already buried in a pile of great ideas, what we lack is resources, so talk to me about that. Makes for some awkward conversation. I'm not unsympathetic, because I've been on the other end of that stick as an inventor trying to license technology.
Cal, detectivity is strictly an electrical parameter which generally speaking doesn't depend on what searchcoil you have installed, the operating frequency of the machine, or how you have the controls adjusted. Also with respect to lag coefficient, that's an electrical and software parameter independent of searchcoil design and operating frequency, but is often dependent on what mode you're using. It is common knowledge that certain searchcoil designs offer quicker or slower response than others, so lag coefficient doesn't completely describe the speed of machine response.
Commenting on the quote in one of the posts: Back in the early 1980's I thought that single-frequency discriminators had pretty much reached the limits of what was possible, and predicted that multiple frequency would soon demolish the single-frequency market. Boy, did I call that one wrong! We are still making major advances in single-frequency technology. The Omega may not be our most "high-tech" machine-- in fact it has its origin in what was originally intended to be a cheapie platform-- but it incorporates our most recent knowledge, which of course the T2 does not since it was released several years ago. .....The primary engineer on the Omega was Jorge Anton Saad, a relative newbie to beeperdom, and it was while working on the Omega that the arcane science of metal detector design finally came together between his ears. I was involved of course, but what made the Omega great was that he was not just following direction blindly, he understood what he was doing and it was on the leading edge of metal detector design. The static pinpoint and motion all-metals (autotune) modes on the Omega are pretty good, but they fall short of perfection and don't break any new ground from the perspective of a user. The performance forte of the Omega is its discriminator, which incorporates numerous improvements over most of the prior art. When people praise the Omega's discriminator, they're describing the result of a lot of hard work. [So much hard work, that if the Omega hadn't turned out as good as I told Jorge it would, I think he would have hauled me over to Juarez and killed me. Even nice guys have their limits!]
The Fisher F5 was John Gardiner's project, which was closely related to the Omega. The two machines differ primarily in mechanicals and user interface design, the performance is fairly similar. The F70 came after the F75 and before the F5 & Omega. The F70's discriminator shares some of the characteristics of its predecessor the F75, and also with the F5 & Omega which borrowed from it and added some of their own improvements. There hasn't been a lot of comment on the forums relating to the difference in the discriminator behavior between the F75 and the F70, because there the discussion has tended to revolve around "is the F70 really as hot as the F75, or even maybe hotter?" and the relationship between price tag and features.

You stay away Juarez not good idea for USA beeper engineers to come visit.
