AT Pro Readings
Hi,
I am using an AT Pro with a Garrett 8 X6 " Coil. My machine reads 72-73 on zinc pennies, 77-78 on an Indian head penny and 51-52 on a buffalo & clad nickel. A clad dime is 81-82 and clad quarter is 86-87. These are very consistent on my AT Pro with the coil mentioned above. If I remember correctly the bigger coil that comes standard with the AT Pro reads the same . I do like the smaller coil better, I think it sorts out the junk better. Nickels are hard because if you notch out pull tabs, ( 53 ) you will likely notch out the nickels. I run in the Pro Zero with two notches less than full sensitivity. Hope this helps you. Good luck with you machine, it's a good coin shooter. I hunted today and got a bit over $6.00 in clads at a Jr. High football and soccer fields.
