It has never been easier to see your swing—and to do it, you don’t even have to go see an instructor with an elaborate teaching studio. The technology that was once the province of only professional-grade cameras has trickled down to the consumer market, making it easy and inexpensive to take high-quality video. The best example? Apple’s iPhone 8 Plus, the latest in a long line of impressively engineered smartphones. The 8 Plus has a 12-megapixel camera that shoots 4k video at up to 60 frames per second—good enough for virtually any golf application. Many top teachers use it as their go-to tool for recording lesson progress. If you need more horsepower, Sony’s RX10 III camera will shoot up to 960 frames per second and offers more flexibility in less-than-perfect lighting. It also has built-in WiFi, which makes transferring photos and videos to a smartphone or desktop easy. Live View Golf’s camera works with your smartphone or tablet to let you see your swing as it happens. Mount the camera on your bag, and it sends a live feed to your device on the ground, so you can make adjustments in real time.
