VDI.s on 9" HF coils

[Flintstone]

Hi ALL, I just got my new 9" HF coil and the VDI's are all a lot higher than the LF coils. Dose anyone have a list of VDI's for the HF coils? With the LF coils 83___ 87 is a penny or dime on the HF coils is pull-tabs, what is the VDI for gold or silver? I was getting nickles in the 70"s , that is where Penny's go. If anyone can help I sure could use it. Thanks flintstone

The numbers depend on the frequency you run. The lowest frequency is pretty well already covered by available charts. The higher frequencies really put silver coins and clad into a narrow range from 91 on up. Gold is so variable that a chart is of little use.

Bury some items and develop your own understanding of what the numbers indicate.

Thanks Paekgt, I am used to the LF coil, I dug so many pull tabs that if they were worth a penny each I could of payed for my coil. They were hitting in the 80s and that on the LF coil was always a penny or dime. I know gold is all over the place, but is there where 14k hit most? This HF coil is going to take some getting used to. Thanks flintstone
