Omega 8000 solid 99 TIDs

I haven't gotten anything good with it. But, almost every 99 reading is a swing from a low tone, so I started to see that. What you might want to try doing is to completely drop the discrimination or put it into AT (all metal) and find out more about the target. If you are just coin hunting AT and pinpoint will help to give you the shape of the target, that is if it isn't in iron.
So far, by putting the discrim all the way down I can usually see that it is iron. Coins don't ever hit so high when next to iron, that I've found anyway. When coins are in iron they hit different not as solid as the 99 reading for sure.

You're seeing the effects of iron wrap around. Picture the conductivity scale in 360 degrees, with iron starting at zero (or 1 in the case of the O
and the highest conductor going to the top of the conductivity scale, with 1 and 99 meeting in the middle. At times the target will bleed up or down a few #'s on the scale, just like we see on jumpy coins or trash targets, especially if their corroded or co-located with other targets, the same thing is happening as rusty iron bounces around.
If you sample a silver dollar with your O8, I believe it will hit in the mid 90's, so anything in the 97-99 range isn't going to be good IMHO.

The first thing to remember is that the VDI read-out can vary based upon the particular search coil in use. With MY omega and MY three coils, the 'stock' elliptical concentric reads most coins about right, but the 5" and 11", both DD designs, seem to produce a slightly higher VDI number for the same targets.
Second, due to the variables of using different coils, the influence of nearby trash which can mask a target's anticipated reading, I NEVER put full stock in any detector's VDI. I simply use it for what it is and consider all the variables involved.
Third, keep in mind that some desired finds WILL produce higher VDI readings. For example a few months ago, while hitting a lot of park and school playgrounds, I got a solid '98' that would flicker to '99' periodically. You can tell a larger more solid target from a shallow, weak target that fools you and from less than 2" (about 1"-1

Nice posts Monte and Cal (I learn a lot from you both).
But a question Monte. Can you go into details more about the d2 mode and iron, and d3 for that matter. I didn't get much of a response on that thread I started and am really curious about the difference (advantages, etc.) of those two modes. As I said in another thread I am really liking the d3 mode after one hunt (but only got one coin with it). It seems like there may be more target info in the clarity or lack there of of the d3 mode, compared to the modulated longer sound of the d2 mode (at least on shallower targets). Am I on to something? (I'm being very general here and leaving lots out, if you think it better post it in the thread I started as it makes more sense for others finding that info.)
Thanks
I know I have mentioned this in round-about ways in some former posts, and many forum posters comment on why they like, or don't like, certain Tone ID options. Naturally, a lot will have to do with how you set the Omega up for various hunting environments, such as the Discrimination level, what type(s) of targets you're primarily searching for, what site target information you are interested in, and the general good-target depth at various locations, to name a few. I have my favorites, for good reason (in MY opinion for MY styles of hunting), and I am sure that one or two of these Tone ID options are favorable to every detectorist.
'Earthmansurfer', while there are four (4) audio Tone ID choices, there are really just two (2) different sets or approaches to Tone ID and each of those has a paid to select from. There are d1 and d2 which provide one type of audio response that are really not in the "Tone" category, and then d3 and d4 which give us a different set of audio enhancements as well as either 3 or 4 different Tone ID audio tone categories. Of these offerings, and living here in the USA where I can do some avid 'flash-money" coin hunting in urban sites or get out and away to search older places where targets might be a bit deeper and I am after many types of targets and not singling out typical US coins, the two Tone ID options I prefer are d4 (many urban sites) and d2 (most out-of-town or more inquisitive sites.
As a rule, many hobbyists who are engaged mainly in "coin hunting", especially in urban environments such as parks and schools and picnic areas and sunbathing sites and playgrounds, like to rely on the visual Target ID information, especially the 8 TID "zones." Because they like to visually ground or classify potential coin targets, many will also favor using more Audio Target ID help which comes with the d3 and d4 options.
Most serious 'relic hunters,' or even coin hunters who like to seek out the deeper coins and/or go for coins and other targets that might be at mid-depth or deeper and won't give a proper visual TID, often like the d1 or d2 options because there is a lot of valuable audio tone information provided, and some of us find them to provide just a little bit more functional depth-of-detection of the four available Tone ID options.
Okay, let's first take a look at the d1 and d2 offerings on the Omega 8000. This information is provided on Page 18 of the Owner's Manual, in general, and I'll add a bit of my personal opinions for what it's worth. Remember, too, that the Tone ID options only apply to the motion Discriminate mode.
The d1 option is described as: "Medium-to-high pitch tone, varying in proportion to target signal strength. Large shallow objects will produce a squeal. The variable audio pitch provides you more information about the detected object. Volume and Pitch increase with increase in signal strength."
Monte's Interpretation of the d1 function: A decent modulated audio varying from weak (deepest /smallest) to strong (shallow/large), and incorporating a VCO-like audio on mid-to-shallow targets. In addition to the standard modulated audio (volume of audio response) to help define target size and potential depth, the variable audio pitch (squeal) on larger or shallower targets can provide additional information to suggest size and depth (or lack of).
In the d1 Tone function, ALL targets, ferrous or non-ferrous, will produce a similar sound with regard to signal response based on target depth or distance from the coil for typically desired (coin-like) target sizes. They all sound somewhat alike, except those targets that are rejected (Discriminated) will not produce and audio response. So, if you're the type who uses a rather high level of Discrimination that knocks out all Iron and even some small Foil targets, then d1 can work for you to provide a little better depth of detection if you listen for the weaker, softer responses..
The d2 Tone option is blessing for those of us who like to "hear-it-all" because we hunt with no Discrimination (a setting of '1') or only partial iron rejection. Personally, I like to know what is in the area. If a site is rather clean with very few iron targets or even non-iron trash, then maybe a d3 or d4 search choice for some would be fine. However, good-target masking can be a terrible thing, and iron-based targets can cause the greatest amount of target masking. Also, if I am searching any site that might have had buildings torn down or burned down, or the type of activity that would have had nails scattered from opening boxes, or any other amount of iron debris scattered about, I want to know the iron is there so I can better concentrate and listen for any 'iffy' or 'questionable' signal in amongst the iron.
Therefore, I like to hunt with a Discriminate setting of '1' so I can hear everything, and the d2 Tone ID option works just like d1 with the following difference. In addition to the variable higher-pitched Volume (loudness) and squeal (variable pitch from shallower targets) you get from Non-Iron targets, the iron junk usually produces a low-tone (bass like) regardless of the signal strength.
So, d1 and d2 have the ability to provide a little better depth of detection of the four audio tone options becayuse they rely on a good modulated response, and they have the added pitch function on shallower targets, and the d2 function alerts the operator to probable iron junk. The Sensitivity
level will have a bearing mainly on the overall depth of detection and not affect the modulated response as much as with the d3 and d4 tone options.
The d3 and d4 Tone ID options really aren't for many hobbyists. That is, with the d3 a and d4 Tone ID functions, as Monte describes them, means the d3 feature produces three (3) levels of audio tones: A Low "bass" Tone for Iron, a Medium Tone for Foil, 5

Just wanted to say thanks Monte for taking the time to post that. I'm gonna put that one in my Word tips file!
