I sent my AtPro back to Garrett do to issues I was having along with the pro pointer . I just got the machine back and found that they have changed things to military specs. Because I live in the great state of New York and the weather is a balmy 10 degrees today, I chose not to check it out. I would like to hear from other owners that have the upgrade done to weigh in and let me know how the upgrades are. So far I like what I see.
