Anyone can give subjective feedback on a golf swing, but only the Swingbyte will give you absolute exact real-time data on what you are objectively doing wrong. The Swingbyte helps you bring your golf game to the 21st century, by tracking everything from the degree you sliced it to the swing speed. They have a free downloadable mobile app, as well as a web app that you can easily access with your MySwingbyte account to access all your previous records. There is an awesome bluetooth feature that allows you to turn on the ‘add swings,’ so you can pull out your phone and see what you did right or wrong the second after you swing. The question on everyone’s mind is likely, well how the heck am I going to get a better swing with some heavy attachment on it? Well, they thought of that ahead of time, and created it to weigh less than one ounce… meaning you won’t even know it’s there. The Swingbyte 2.0 is available on their website or Amazon.
