I was wondering if someone could tell me, at what number does the high tone come in at on the Delta?
Thanks.
Mick Evans.

I SET MY AT 8 OR 9 OR SOME TIME 10 TO GET A HIGH TONE

I guess I'm not sure what you're referring to, Dog. If you're talking volume control settings, that does have an effect on the volume of a high tone (more than the other two) but on any setting above 1, you should be able to actually hear the high tone. Low battery can come into play on this also. Now if your hearing and or headphones don't allow that to be, then there's a different issue. I took it that Mick was asking specifically what ID numeric value is the bottom end of the high tone range. That is 80 just like on all the other Greek/Frat Boys detectors.

Thanks for that Brad. Yes, I was refuring to the ID numbers. It's unfortunate that is a little high for me. I thought that because it was 3 tones instead of 4, it may have been lower like the other brands of detectors. Our Aussie $1 and $2 coins come in at 79 and 77 respectively.
Just missing the high tone.

Gamma or Omega. With the lower-end models the Discrimination eliminates one TID segment with each step of rejection. With the Gamma & Omega you can fine-tune the upper limit of acceptance. I know, you might like to hear the high-tone audio, but sadly your mentioned coins just don't fall into that conductivity range.
I just tinkered with the Gamma and a foreign coin that reads in that '77' to '79' range and simply ran the discrimination up to knock out everything below a US dime (which was still '80'),and then you can step it back down to where you'd like it. I went down to '77' and '76' and '75' since the coin mainly read '78' and i got a solid audio each time. No, it wasn't the high tone, but that way I was rejecting targets that were less conductive but close.
Then, too, we know that when the targets are in the ground that can make a differences in how they read when located. If conditions cause a particular piece of junk that might 'read' 71 out of the ground but it is bumped up to respond as if 78 when in the soil, then you would get a signal on that as well. It doesn't matter which detector if the circumstances cause this shift.
Also, if in bad ground, the Gamma and Omega have both Ground Grab and the 1000 step manual GB to set it for best performance and depth of detection. just something to consider, but I know both model cost more than the Delta.

Thanks for that info Monte. I was hoping that it might be like the Ace and X-terra 30(5) with the 3 tones. They both give a high tone on our goldies.Unfortunately, our coins start at around 53 for a 5c piece, 57 for a ten cent piece and go up to 79 for a $1 coin. Our old coins hit higher as they are made of copper and silver. The Delta sounded like it might have had an advantage over the Omega in that department, but not so. The Delta does have a volume control which my Omega doesn't have. Can't figure why they would dump such a valuable asset on a higher value machine. It's far too noisy without it and I hate wearing head phones. 4 layers of gaffa tape has reduced the volume. but that nothing like having a volume control.
I'm hoping to get out with the Omega a bit more often now. In the process of selling the X-Terra, so one less detector to get distracted by. I haven't been overly thrilled by it's TID. It seems to be less reliable than most other units. Yeah, I know you don't hang your hat just on a TID, but it's performance is as just mentioned.

Mick, I guess I was a bit tired last night after I posted and forgot what model(s) you had.
First, the Volume control isn't really what you want, especially if some of your coins have a higher conductivity read-out and/or they are larger in size. Why? because one issue I have with the Volume control on the Delta and Gamma is that you will lose depth and responsiveness if you reduce the Volume level too much. At the high setting of '10' everything sounds 'OK'', but when reduced to about 3-4 I can lose a big silver US dollar coin, and almost not respond to a small pile of 3-5 US 25Mick in Dubbo said:

I'd opt to add something to one of Monte's posts, but I guess that day has arrived. 
Maybe it's just the coffee. 
First of all Mick, of course Monte is correct in what he said. I also don't really know just where all of the desirable targets you're wanting to find fall out with ID number ranges besides the two coins you've mentioned initially and now what you've elaborated since. I guess worst possible case is that you'd want to hear everything, (maybe minus the iron?) while utilizing the most use of tone differentiation as possible. Soooo, with that in mind, you do as Monte suggested by discriminating up through maybe 75 and then notching in all the rest, or whatever fits your needs AND run the detector on 4 tones. This would yield a unique tone for nickle classed targets, and another for foil, tab, and your coins for the 76 through 79 ID's. Obviously if you could notch out any of the mentioned segments, that would mean lessening the range of targets that you'll have to visually check before deciding to dig. Again, this would be possible on the Gamma and Omega but not the Delta. IF this sort of setup is of interest or possible benefit, you might even want to consider an F-5 because it has greater resolution in the zinc range (55 through 64 vs the 75 through 79 of the Gamma/Omega) so you might be able to tune a little more exacting for those coin values you mentioned or at least have a little better "trash or cash" idea before you dig depending on what other junk items you encounter that fall in close to the coins' ID's. I know this all is a departure from your original question, but I thought just maybe it might help or provide some additional food for thought. Oh, and speaking of the Delta and the F-5, those two allow you to notch out targets in the (US) 50 centers on up. Sounds like that might possibly be of use to you too. Good Hunting to ya!

This feature also affords pretty much eliminating virtually all of wrap around providing the operator is comfortable in notching iron and the 50c and up segments. Comes in handy AT TIMES.

Thanks Brad and Monte.
It seems I need to reread my instruction manual about notching. Unfortunately, our gold coins are in screw cap range, but at least on shallow targets, you can tell them apart, partly by the overload feature. depending on my mood, if I don't want to hear pull tabs, then I turn up the disc to 59 or so. 20c pieces come in at 61 and 50's at 63 or 4. Again using the overload feature, it's real easy to sort out coins from pull tabs, if they are close to the surface.
I was kinda hoping that the Delta being a 3 tone machine, might have had different spots on the TID, but it's not to be. The 4 tones is no good, but like you Monte I really like the modulated 2 tones. It's one of the features that attracted me to the Omega.
I was very surprised when you said that the volume control had such a negative impact on targets! That's something that I would normally associate with a threshold tone. Never come across that issue before. Sounds like it needs addressing. Apart from the cord getting in the way, I've both had issues in the past with using headphones (due to an injury to my neck 6 years back, it's only been the last couple that I'm now able to take the weight of headphones on) as well as having no noticeable improvement in sounds verses the Speaker of the detector. That point was brought home to my 16 months back when I took my X-Terra 70 out for a club hunt on the gold fields. I was using RPG's, which I guess are not the best brand, and while detecting in prospecting mode on some very noisy ground, I found that I could hear the sounds through the speaker more clearly than the head phones! Having a strong wind blowing though the headphones didn't help. Having recently bought another detector that came with Koss head phones, it's the first time that I could say that I'd have any confidence in using head phones. The only catch with them, is there's no volume control; so using it with the Omega would be far too loud. I've never seen Killer Bees head phones over here, so have no idea on there effectiveness. It's clear to see that you like them
It appears that the Omega is going to be, the most practical light detector that I can find to date, so I'll stick with it and get to know it. Who knows; maybe one day someone will make the perfect combination, but it looks like that could be a long weight, although something may show up.
