Nearly six years after introducing its original smart swim googles, Form has announced an upgraded version called the Smart Swim 2. However, they’re now smaller and lighter, and while battery life is a little shorter, it’s because of new features like a digital compass and heart rate tracking. The Smart Swim 2 goggles are available starting today through Form’s online store for $279. A new optical heart rate sensor means swimmers don’t need to wear other fitness trackers if that’s a metric they care about. When swimming in a lake or river, the Smart Swim 2 goggles can help keep you on course by showing your current compass bearing.
