Taking my wife home yesterday I received a traffic annunciation. "Traffic, 11 O'clock, same altitude, 1 mile." The traffic screen popped up on the 650 and the iPad. I looked outside the window and had to take immediate evasive action, so I entered a 60° degree left bank and pulled hard on the yoke. My wife screamed what did you do that for? Apparently she missed the traffic alert. I said I'll show you, as I wanted to get my eyes back on the other airplane that turned out to be another Mooney. Rolled back to 30° right where I saw it rolling back from a bank to the left. I don't know if the other Mooney had ADS-B in but I'm sure the other pilot saw my maneuver considering how close we were. When my wife saw the other Mooney, she was like "OH, that ADS-B in is awesome..." I have to say I am truly impressed with the GTX-345 and GTN-650.... The combo gave me time to "see and avoid" much better than the plain old two sets of eyeballs in the cockpit...
