These days, GPS watches come with such a mind-boggling array of functions that it would be impossible to use them all in one lifetime, never mind understand what they all mean. Sometimes, however, it’s worth doing a little research to uncover what different modes and functions do, and when you might want to use them.
Take, for example, the Coros Apex 2 Pro and Coros Vertix 2. Both watches have built-in GPS, which is ideal for when you want to track your outdoor workouts. But as you’ve no doubt realized, while these watches can last for weeks without needing to be charged when you’re not using GPS, the moment you turn on GPS your battery starts draining much faster.
