Attach the small sensor to your club, and the vibration created at impact sends swing data (including clubhead speed as well as face and path angles) to a wireless device via Bluetooth. Unlike Zepp, Swingbyte can record video of your swing, allowing you to play back the virtual swing next to the real thing.
Your grip-it-and-rip-it philosophy does you no good unless you get the first part right. The SensoGlove has sensors in each finger; if you grip your club too tightly, it'll beep, alerting everyone else in your foursome and spawning all sorts of "choke" jokes. But it'll also save you strokes.
The Zepp sensor, which contains a gyroscope and dual accelerometers, attaches to your glove and, like Swingbyte, transmits data to a mobile device. But the app does more than just display numbers; it replays your swing in 360 degrees and also compares your hack with an ideal swing. Once you've used it to master golf, the sensor can be used to chart your baseball and tennis swings.
