Shot Stats Challenger
While we’re on the subject of fine tuning sports skills, our tennis swing could also use a bit of help. But this time it’s not the ball that’s wired: instead, a tiny device snaps onto your racket like a standard dampener, reducing vibrations as it collects metrics on speed, spin, impact point, and distinguishes between shot types like forehand, backhand, serves, and smashes. A Bluetooth-synced app breaks down statistics and tracks progress, though the device also works as a standalone unit on account of its bright LCD display and optional audible feedback. And don’t even think about going easy with one on your racket: its lightweight aluminum body is entirely impact resistant, and remains in place until its latch is manually pulled.
