Monitoring your heart rate while swimming is essential for tracking performance, improving endurance, and ensuring safety. A good heart rate monitor designed for swimming can provide accurate data underwater, helping swimmers maximize their training. Unlike standard fitness trackers, these devices are built to withstand water pressure and maintain functionality during laps or open-water sessions.
When choosing a heart rate monitor for swimming, key factors come into play. Water resistance is critical to ensure durability and reliability during use. You’ll also want to consider comfort, as the monitor should fit securely without causing irritation during long swims. Additionally, accuracy both in and out of the water is essential, as well as compatibility with apps or devices you use to analyze your workout data.
We researched and tested multiple options to find the best heart rate monitors for swimming, focusing on those that deliver consistent performance, ease of use, and value.
Best HR Monitors for Swimming
We’ve rounded up the best HR monitors for swimming to help you track your performance and stay on top of your fitness goals.
1. Garmin Swim 2
This smartwatch stands out as an excellent choice for swimmers who want accurate heart rate monitoring and helpful swim metrics.
Pros
- Tracks underwater heart rate reliably.
- Slim design feels comfortable during swimming.
- Great battery life for extended use.
Cons
- GPS in open water can sometimes take longer to connect.
- Interface may seem a bit dated compared to newer models.
- Price might feel steep for casual swimmers.
The Swim 2 quickly impressed us with how smoothly it captures swim data. Wearing it felt natural, even during long workouts in both the pool and open water. The wrist-based heart rate monitoring is surprisingly consistent, eliminating the need for a chest strap, which boosts convenience.
Using it during open water swims added an extra layer of insight. The GPS did well for pacing and stroke tracking, though there were rare times when syncing took longer than expected. For open water enthusiasts, the metrics like stroke efficiency and pace are invaluable.
In terms of design, the slim profile is clearly tailored for swimmers. We never felt it was bulky or in the way, and it doubles as a reliable everyday smartwatch for sleep and step tracking. If you’re serious about swimming or triathlon training, this is worth considering despite its slightly premium price.
2. Polar Verity Sense Heart Rate Monitor
This is a comfortable and versatile option for tracking heart rate while swimming and working out.
Pros
- Exceptionally lightweight design ensures ease of wear during long swims.
- Multiple connectivity options make syncing with devices and apps straightforward.
- Comfortable armband eliminates the frustration of chest straps.
Cons
- Separate charger adds to the inconvenience of upkeep.
- Removing it from its cradle can feel a little fiddly.
- Occasional issues connecting reliably to devices through the app.
We found the Polar Verity Sense to be a refreshing change from traditional chest strap monitors. The armband design provided much-needed comfort during our swim sessions, staying securely in place and avoiding unnecessary adjustments. It feels natural during prolonged use, not restrictive or irritating in any way.
Connecting it to our swimming goggles was surprisingly intuitive. Tracking real-time heart rate data was smooth, and syncing to our fitness apps worked consistently for the most part. Although small, it packs enough functionality to meet varied workout needs.
One minor downside is that it requires a dedicated charger, which isn’t as convenient as a plug-and-play option. Additionally, the cradle mechanism isn’t as seamless as we’d hope. While it didn’t affect our overall experience heavily, it’s worth keeping in mind if maintenance ease is a top priority.
3. POLAR OH1+ Heart Rate Monitor
This product is a reliable and simple option for swimmers who want comfort and accuracy in heart rate tracking.
Pros
- Comfortable armband that stays secure during activity
- Easy to pair with multiple devices and apps
- Built-in memory for recording data without a phone
Cons
- Limited battery life compared to other monitors
- Pairing issues can occasionally occur
- Swim goggle holder may be missing in some packages
The POLAR OH1+ is designed with ease of use in mind, and we found its lightweight armband and snug fit ideal for long swim sessions. Being able to track our heart rate without worrying about adjusting straps made a noticeable difference in comfort. Even when worn with swim goggles, the sensor didn’t shift around or become intrusive.
Connecting the OH1+ was a breeze. Syncing with our favorite app only took a few seconds, and having the option to link it with smartwatches or fitness equipment via Bluetooth or ANT+ gave us the flexibility to track workouts the way we wanted. The onboard memory also allows us to leave our phones behind while swimming, a feature we appreciated during intense laps.
While the OH1+ delivers reliable performance, issues with battery life and pairing occasionally came up. It lasts about 12 hours, which may require frequent recharging for regular swimmers. Additionally, some units might arrive without the goggle strap clip, which could be frustrating for certain buyers. Despite these minor drawbacks, this monitor remains a solid pick for its accuracy and thoughtful design.
Buying Guide
When selecting the best heart rate monitor for swimming, it’s essential to focus on features that cater specifically to water-based activities. Here’s what we need to prioritize:
1. Waterproof Rating
Not all heart rate monitors are created for water use. We must ensure the device has at least a 5 ATM or equivalent waterproof rating, which makes it suitable for swimming and other aquatic environments.
2. Comfort and Fit
A snug, secure fit is crucial when using a heart rate monitor in the water. We should look for options like soft straps or sleek designs that don’t interfere with swimming strokes or cause discomfort.
Table: Key Features to Compare
| Feature | What to Look For |
|---|---|
| Waterproofing | Minimum 5 ATM rating or specific swim-proof features. |
| Data Accuracy | Precise and reliable heart rate tracking even in water. |
| Comfort | Lightweight, ergonomic, and adjustable straps. |
| Battery Life | Long-lasting power to avoid interruptions mid-swim. |
| Connectivity | Syncs with apps or devices for data tracking. |
3. Data Accuracy
We need to prioritize accurate readings in aquatic environments. Optical sensors designed for underwater use or chest straps with advanced tracking capabilities are usually more dependable.
4. Connectivity Options
Models that sync seamlessly with our smartphones or fitness apps help us analyze performance. Bluetooth and ANT+ compatibility can be particularly useful.
5. Durability
Swimming requires a robust monitor. We should check for materials that resist chlorine, saltwater, and wear over time.
By focusing on these features, we can find a product that meets our needs and makes our swim training or leisure time more effective.
