Unless you have expensive pro-level hardware, you're probably not getting as much out of your pitching sessions as you could. The Strike Smart Baseball gives you access to a wide variety of stats using nothing more than some sensors tucked inside the ball. With a full-grain leather cover and the exact same size, weight, and number of stitches as an official MLB ball, it feels just like any other. But when you throw it, it collects metrics like speed, spin rate, location, and rotation axis, then uses all this to give you a 3D trajectory of each pitch. It charges wirelessly, connects over Bluetooth, and lasts up to 12 hours per charge, so your arm will wear out long before it does.
