The Garmin Swim 2 Swimming Smartwatch helps you monitor all your vitals plus performance metrics so you can get the best out of your training. This smartwatch offers essential vital metrics such as heart rate and stress monitoring plus Body Battery Energy Monitoring that tracks your body energy levels so you can find the best times for activity and rest. To enhance your swimming experience, it has an Open-Water and Pool Swim Mode that uses the built-in GPS, so you can train in lakes, oceans and rivers while recording distance, pace, stroke count, stroke rate, stroke distance and SWOLF. Track your Critical Swim Speed which approximates your anaerobic threshold speed, while the Drill Logging tracks time and distance for drills such as kicking, one-arm swimming or sculling. When you need a break, the Swim 2 lets you track your rests with two types of timers, as well as let you create your own custom workouts in the Garmin Connect app and get them on your watch for training. Receive emails, texts and alerts right on your watch, when paired with a compatible smartphone, and forget about running out of juice as its internal, rechargeable battery provides up to 7 days in smartwatch mode, 13 hours in GPS and optical heart rate (OHR) mode and 72 hours in pool and OHR mode. Take your swimming to the next level with the Garmin Swim 2 Swimming Smartwatch!
