CoRe? Does anyone have a TID READOUT chart

Does anyone have a chart readout of the Nokta FORS CoRe of relics/coins here in the states? Or would air testing them be similar to ground readings/TID numbers?

Also, if you do, are the numbers much different between the 3 coils?

Looking for brass/flat button readings to lead/3 ringers. I figure I can figure out the coins of anything reading 82 or higher?

Thank you,

The manual states US nickels at 56-58, dimes at 84-86 and quarters at 88-92. I have only been out once and I think zincs were about 82. It's a pretty tight grouping. Aluminum tabs with the tail bent around were coming in around there too. I need more time on it.

I encourage all using both the Racers and CoRes units to get you some screw caps, drinkk lids, beer tops. And get you some late model pennies. With small coil sweep all the targets and note both the quality of the tone and the length of tone. There's a big difference. Just today for example I got a 82. Tone was blah and long. I hadn't found much so dug the target for gee wiz. Turned out to be a light bulb base. I saw this earlier again this week. And I'll bet the farm if you would have hit both of the light bulb bases with say an Etrac, you'd thought copper or silver all the way. I know because this happened to me more than once when I used to run Etracs.

I haven't dug any real deep coins, mostly surface down to 4 inches. The tones from those about blew my headphones off. Very sharp and defined.

I agree tab. Like TNSS said, sound trumps TID READOUT. And like I just posted (I've got alot to learn) but the aluminum sounded "HOLLOW" if that makes sense. Whereas the coinage was tighter sounding to me?

TNSharpshooter is soooooooo right about "training/retraining" your brain to listen to what the machine is telling us. Oh boy. I've got some retraining to do!
