Amazfit's dual-band circularly-polarized GPS antenna technology, named MaxTrack, enables this GPS smartwatch to pick up almost 100 percent of satellite signals. This technology reduces multi-path interference to track your position with the maximum amount of accuracy, even if you're running in dense cities with tall buildings or parks with high trees. The Zepp Coach harnesses the power of AI to provide personalized running plans, which are generated based on your current level, target race type and date, and your goal for the race. To help you build up to race day in the ideal condition, Zepp Coach will intelligently adjust your plan every week based on your performance, and provide scientific guidance as you progress. With this sports watch, you'll always know where to run. Download a color map of the area you plan to run from the Zepp App and import it to the watch, to enjoy a detailed understanding of your surroundings. Pair the map with a matching imported route file and navigate with incredible precision as you run. Make and receive phone calls using the watch via Bluetooth connection to your phone, to keep up with personal and professional contacts while on the run. Store your running playlist on the watch and listen to music through the built-in speaker or your connected Bluetooth headphones.
