thanks enamel, i should have asked my question alot better than i did, i was in a hurry when i posted, apologize for that. after doing this a couple months my eye is picking up the abnormalities, just got learn the different errors and varieties better and what is damage and what isn't. i had 2 different answers on this 5 in the nickel and asked on a facebook group and a fellow there said it was clash. i am not discounting anyones opinion and have learned not everybody agrees on certain things and that's alright. i do know its a hobby i am growing to enjoy until i can get out detecting again whenever the weather breaks
