6 Best Heart Rate Monitor For Swimming
From leading brands and best sellers available on the web.
Buying Guide for the Best Heart Rate Monitor For Swimming
When choosing a heart rate monitor for swimming, it's important to focus on features that work reliably in water and match how you plan to use the device. Not all heart rate monitors are suitable for swimming, so you should look for models that are specifically designed to withstand water and still give accurate readings. Think about how often you swim, the environment—whether it's a pool or open water—and what other features you might want, like data tracking or compatibility with other devices. Understanding key specifications will help you decide which monitor best fits your needs and swimming habits.Water Resistance RatingWater resistance rating tells you how well the heart rate monitor can function in water. This is crucial for swimmers, because regular electronic devices might stop working or get damaged when wet. Ratings are usually given in meters, like 30m, 50m, or 100m. For swimming, you want at least 50m water resistance. Models rated at 30m are generally splash-proof, while 50m or more can handle being submerged for longer periods. If you swim laps in a pool, a 50m rating should be sufficient, while open water swimmers may want something rated even higher for added durability.
Heart Rate Measurement MethodThis specification refers to how the monitor reads your heart rate. There are two main types: optical sensors (built into wristbands or watches) and chest straps. Optical sensors use light to detect blood flow, but may lose accuracy underwater. Chest straps use electrical signals and tend to be more accurate in water. If you need precise data for training or competition, choose a model with a chest strap designed for swimming. Casual users who just want basic information might prefer the convenience of a wrist-based sensor, even if it sometimes sacrifices accuracy.
Data Storage and TransferData storage and transfer concerns how the monitor keeps and shares your heart rate data. Swimming often interferes with real-time wireless transmission, so some monitors store data locally and sync it with your phone or computer after your swim. Look for options that save session data internally for later upload—this is especially important for swimmers, since Bluetooth and ANT+ don’t work reliably underwater. If you like to analyze your performance or log workouts over time, make sure the device includes this feature.
Swim-Specific FeaturesSome heart rate monitors include features made just for swimmers, like lap counting, stroke recognition, or swim pace tracking. These additions can make it easier to track your progress and tailor your training. If you’re interested in more detailed swim analytics, consider monitors that offer these extra features. More casual swimmers may find them unnecessary, in which case a simple and reliable heart rate monitor is enough.
Fit and ComfortSince you'll be wearing the monitor in water, a comfortable and secure fit is vital. Straps that slip or irritate your skin can be distracting and lead you to stop using the monitor altogether. Try to find a monitor that’s made from soft, hypoallergenic materials and designed to fit snugly without being tight. For chest straps, look for adjustable bands to get the best fit. If you have sensitive skin or swim for long periods, comfort should be a top priority.
Battery Life and ChargingBattery life indicates how long your heart rate monitor can work before needing a recharge or battery replacement. Long battery life is important if you swim frequently or don’t want to worry about running out of power during a session. Some offer rechargeable batteries that last for several days, while others use disposable batteries that can last for months. Think about your routine—if you swim regularly, choose a model with a battery life that won’t interrupt your workouts.
