Silver Rosie's must be the ice breaker....I just got my first silver too and it was a Rosie....hope you had the same elation I did when I saw it in the hole.
Yes I am impressed so far. I started with a bounty hunter QD II. It was enough to get me hooked. But I kept wondering what I was missing due to depth mainly. It seemed I was finding the majority of my coins at 4" or less. Think I only found a couple around 8" and they were the bigger coins, one dollar coins. With the AT PRO I found a small coin spill at about 7" and the Rosy at 10". Felt like I was digging forever.
Congrats on your first silver and your AT PRO. You will really like it. I to started with the BH QDII and found some good stuff to get me hooked and slowly upgraded to the pro. Now I can't get enough HH
That is the most exciting feeling! Digging my first silver will be one of my favorite detecting memories ever (mine was a 43' P War Nickel). Now that you've broken the ice, your coil will find its way over more and more silver, but you will remember this one the most!
