I received my ATPro this morning back from Garrett. I've never used it before. I shipped it to them for the upgrade the day I received it from KellyCo 2 weeks ago. Just found my 1st coin in the backyard: a dime from 1997. Also 2 old beer cans and an old nail. I'm watching the 7 tutorials Garrett has posted. I see how discrimination is so critical. I really want to get this discrimination learning curve down. And I can see how detecting is so addicting...
