Just wanted to say Hi. I am from south jersey. I use the AT Pro and I like to hunt for jewelry on beaches, parks etc. One particular question during registration was a little difficult to get right. After running thru every color the sky could possibly be(right now its night, so its black, that didnt work, during sunrise it will be a pink etc) it finally accepted my registration. It didn't specify what time of day the color. Maybe ask what color it is during a clear summer day at noon with no clouds?? lol
