Swim anywhere, train everywhere with the Garmin Swim 2 GPS smartwatch. It provides accurate underwater heart rate data without a chest strap, measuring your heart rate at the wrist 24/7, including during swim activities. You can check your heart rate in real time while swimming, analyze your average and max values during rests, and review your heart rate post-swim on Garmin Connect. This watch works in pools, lakes, oceans, and rivers, recording distance, pace, stroke count, stroke rate, stroke distance, and SWOLF score. Advanced pool features like auto rest and turn-based pacing alerts help you stay on track and meet your goals. It also supports drills such as kicking, one-arm swimming, or sculling.
