Yep have Andys book. Finally found a place where I can experiment with some settings.
Found a sport field at a closed school. that produced 2 quarters 4 nickles 1 dime and one copper penny in an hour- hour and a half.
I know the school has been closed for a least 10 years. I have no idea when it was opened.
I was running the stock coins program and checking against the modified one above. all of the signals hit on both patterns. Next I'll be running with everything below 10 on the cu scale scrimed out to cut down on the can slaw and whacked caps. I am also going drop the lower edge of accepted FE to 24 in the copper silver end of the CU scale, and push the sensitivity and see if I can pull some coins older than the 70's.
I know I may miss a small ring or some other small piece of jewelry,this is more about testing settings and patterns and learning my E-trac.
I'll be posting results.
