Sovereign GT meter. bottlecap and coin differences?

[JASONSPAZ1]

Does the "180" meter for the GT, do a good job in telling the difference between the 2 litre Coca-Coal bottle caps and coins?
Them deep caps are driving me nuts. I have been detecting a very trashy old spot. I know there are deep old coins there. I have been hunting with max disc to try and get the silver only. I only get two types of signals. Deep caps and the deep mercury dimes and wheaties. I cant tell between the two by sound so I was wondering if the meter assigns different numbers for the caps and coins.

Thanks in advance

This is where the 180 meter does help you tell the difference as the tones are real close to one another. I think if you put a screw cap and a dime side by side you would see a difference in the tones, but they are close tones. Now a 180 meter calibrated to 180 for a new quarter the copper pennies, clad and silver will read 179-180 while those screw caps will read 177-178 with many also at 176-177 which is where the new zinc pennies, the IH pennies and some of the first Wheaties will read.There is also some that will read like a good coin but the meter helps a lot for me telling the difference in those close tones.
