I found a Garrett AT PRO for sell on craigslist. I understand when they first came out, there were some issues. How can I tell if this machine is a newer one that has been revised

Easy enough just call Garrett and ask if the machine is 2013 or newer or if its been in for repairs. You can tell by the serial number what year it is. There wasn't a huge problem and Garrett is very easy going to appease customers. If its a good deal grab it. I love mine and wont part with it.
If I recall... all ATP serials start with 5.
Since they started production in 2010 (50xxxxxx) is the first series. 2013 would be 53xxxxxx. The next 3 digits are the day made. the last 3 are for internal use. So 54100xxx would be 2014, April.
A call I made to Garrett CS confirmed this.
