When you’re playing a game of catch, a radar gun isn’t exactly the most convenient way to measure a ball’s speed. The Glove Radar is an affordable way to measure how much heat your friend is throwing your way. It attaches to the back of your glove with a weather-resistant nylon cord. Sure, it looks dorky, but what are ya gonna do?

It uses microwave Doppler technology to measure the ball’s speed as it approaches. When the ball arrives you’ll see it’s speed indicated in mph on the LCD display. The Radar is powered by a single 3V lithium battery, which isn’t rechargeable, but it’s good for about 5,000 speed measurements. You’ll probably be bored with it long before then.
