Babolat Play AeroPro Drive
Sensors in the handle record your game data — pace of shots, contact point, spin, number of strokes, etc. — which can be uploaded to a smartphone. There's new tech in the frame, too. Rather than a traditional flat beam, it's aerodynamically shaped to cut down on resistance when you swing.
"This is a real winner for me. I already play with the regular Aero, so there was no break-in period. I synced my racquet with my phone and noticed the contact point on my serves was a tiny bit low compared to where it should be. Also, I felt I was hitting with topspin, but the feedback suggested I wasn't. It's a bummer that there is currently no way to measure volleys, but overall the Play provides great coaching."
