I had the Omega out for a short stint this morning (about an hour) and topok it back to the park where I found the gold ring last week. I had found pre-decimals coins at this park previously, but none for a while. This morning, apart from four decimals, I found a 1943 silver florin and four pennies, 1941, 1951 and 1952x2. The four pennies were only about 3 inches deep, but were stacked together on edge....they sort of peeled off the side of the hole I had dug. The florin was deeper, a good 4" to 5", and was in dry clay, even though were have had heaps of rain lately. Someone had investigated it before I got to it, but they had not located it...probably didn't go deep enough as the florin was in hard undisturbed soil. I was again using all metal mode, and this time in A3 tone (I am experimenting with the tones at present to see which one I like most). I cant say for sure that I am getting more depth with more precise identification in all metal, but it does seem that way to me.

Omega in All Metal strikes again
- Thread starter Furious T
- Start date
Thanks Elton, thanks Jim. The silver content in our coins was reduced to 50% from 1947, so it was nice to find a "real" one (92.5%). I'm beginning to appreciate the Omega even more by using it in All Metal...Sure, I miss out on the multi tones of some of the Disc. modes, but those tones dont suit our coinage very well. In all metal, I find that I can identify iron (including steel botle caps) more easily from the width of the signal, and the slight variation in the tone that you get with steel. I'm still going through the learning curve, but I'm enjoying the experience.

Thanks again for the report Furious T. (Sounds like a super hero name - but you are one of the few all metal guys, so be it!)
Appreciate your reports. You have really inspired me to try to go back through a spot I worked, but this time in all metal.
Do you watch the VDI a lot? Or is it a sound first then VDI thing?
When I hunted in am I had to watch the VDI when hunting as near everything sounds good when you are hunting in a iron heavy area. I should say to my untrained all metal ears.

Earthmansurfer, I remembered your questions to one of my earlier posts, so I have been taking note of how I react to signals in all metal. Firstly, I have found that all metal isn't suitable in all situations. There is one park where I hunt occasionally where I was nearly driven nut by the noise in all metal....this particular park has a lot of deep iron, but it also has lots of underground electromagnetic interference. I presume cables running underneath the park. Most other places I have been using all metal have lots of junk, but it is bearable and manageable.
While I'm detecting I take note of the audio first (I do this in discriminate mode too). In all metal, however, there are times when I dont even look at the VDI. This may be (and usually is) because of the sound and the width of the audio target. If the sound is long and drawn out, then it is something large (and probably iron). Sometimes the tone of the audio will vary slightly within the signal, even though the signal will not be drawn out in itself. Withe one of my other machines, this is a definite response to something like steel (e.g. bottle caps). With the Omega, I have found that this is the case also, even though the Omega is only using one tone, It seems the VCO picks up on the wider signal of the iron content of the target, thereby varying the response of the detector to the target (this is my surmising, and I dont rely on any scientific knowledge or knowledge of electronics for this explanation, but it is an explanation which seems reasonable to me, as it supports what I find when I have extracted the target). This change is pitch is very slight, but you dont need super expensive headphones to pick it up. During this process I will also have looked at the screen to see what numbers are showing (to see if there is an obvious iron ID or not) and also to see if the numbers are jumping around. As in disc. mode, a good target can still produce variable numbers on the screen if the target is deep or in soil which is made up of different types of dirt (such as red clay which has been top-dressed with brown loam). Most of the parks I detect fall into this category.
So, in short, I listen to the sound first, then if the identification of the category of the target is not farly obvious to me, I look at the screen for more info..If I'm still wondering, I make repeated passes over the target from different directions, which also helpos to determine the size of the target, pinpoint to get an idea of depth, then if I think it is a good target or if I am still wondering, I probe or dig (depending on where I am).
Hope all this helps...Any information here is from my own experiences, but detecting in all metal was inspired in me by an article by cjc in a magazine many years ago. HH

Thanks again Furious,
I think the areas I hunt have so much iron that I'd have to watch the screen for those higher VDI's jumping out. Your post made me think that a lot of the all metal (almost said all "mental") mode is dependent on the amount of ground trash, which makes a lot of sense.
If the ground it cleaner I wouldn't need to look at the VDI and when it's a bit more contaminated I'd have to watch it more as the sounds are a bit saturated and we would need that extras "visual" assistance.
Great job!

That is pretty much what I am running whenever I try a/m, as well. The spots I hunt are just so trash laden and one spot has a good bit of iron as well as the usual park setting trash, that all I am doing is watching the screen. At least in multi tones, I can "listen out" some of the screen watching. I have a couple of woods sites that I use and like all metal for as not a great deal of trash. HH jim tn
it is most often where there is a low level or targets, especially iron trash.
Yes, I can often classify ferrous targets by their width, but not always. When I am in dense iron I prefer to use a smaller coil (usually the 5" DD with the Omega) and hunt in Discriminate mode with a setting of '1' and I use the d2 Audio Tone ID. If you don't sweep too quickly it lets you hear more potential good targets in amongst the iron debris.
It's just good, however, to use a versatile detector with as much adjustment in the Disc. mode, and still provide Threshold adjustment and manual GB to fine-tune the All Metal mode when you opt for it.

Thanks Monte,
The Omega is a versatile detector, and for me, the all metal mode is providing another option to find targets which in the past have been elusive, sometimes through my own impatience or a mere reluctance to dig an iffy target. At present I am using all metal mode a lot so that I can better acquaint myslef with the Omega...I spent about 10 months confining myself to disc. mode and am finding the all metal mode to be yet another facet of this beaut machine. The fact that I am finding targets in areas where I suspected they were, but counldn't quite connect with them demonstrates to me that I am becoming more attuned to the Omega...which makes me happy.
