A High-Performance Smart Watch Built for the Toughest Mountain Sport AthleteS
When you’re tackling tough climbs or rugged trail runs, you need a watch that can keep up with you and support you through both training and race days. The Coros Apex 4 is up for the task, offering a high-performance design with top-of-the-line navigation and GPS tools.
Free Global Maps offers some of the most convenient and in-depth mapping on the market, complete with turn-by-turn navigation, street and trail names, and POIs. The precision dual-frequency GPS with vertical algorithms can also handle any terrain you throw at it, so you can track training across sheer walls and steep treks.
The 3D flyover tools and environment tracking help you stay even more prepared for wherever your adventures take you. You can learn more about the terrain and dive into real-time air pressure, wind, and weather updates to help you make a training or race-day plan. You can also plan and track your journey in the easy-to-use Coros app.
As you track your runs and recovery, you can enjoy a comprehensive look at your training with HRV, heart rate, and sleep tracking. These metrics and training data are always easy to read, in part due to the bright, always-on Memory-in-Pixel touch screen display. You also never have to worry about your battery dying while out on the trails. The 42 mm screen has a 41 mm GPS battery life, and the 46 mm screen has a 65 hour GPS battery life.
