Buyers Guide: Things to Consider Before Buying A Heart Rate Monitor

If you’re an avid swimmer, or just beginning to explore the world of aquatic sports, you definitely need a fitness tracker. There’s very little progress you can actually make without one.

A fitness and heart rate tracker will provide you with all of the statistics you’ll need to make the most out of your workouts, lose body fat, and gain the healthy, toned body you’ve always wanted.

Each of our top 10 Heart Rate Monitors for Swimmers are all high quality, affordable options for anyone’s tracking needs.


Today’s fitness market is stuffed with trackers claiming to be right for everyone, but soon proving to be completely not worth their prices. If you’re a swimmer, you have to be even more careful when purchasing a tracker; if a product claims to be waterproof and isn’t, your hard-earned money just went down the drain.

But, with our picks for Heart Rate Monitors and Fitness Trackers, you can rest assured that each is worth their price. Whether you’re looking for the ultimate tracker, containing every feature you can dream of, or a more simple, affordable option, you’re sure to find one on our list that matches your price point.


Since you’ll be wearing your tracker all day long while you work out (and sometimes, even through the night), comfort is going to be one of your top priorities.

If a band is going to be too tight, or a chest strap will dig into your skin, you’re not going to get the best possible workout. But, with our picks, comfort was one of our top priorities, too. We made sure each tracker was lightweight and adjustable so you can focus on fitness!

Battery Life

While you’re pushing your body to its limits, performing stroke after stroke, lap after lap, you do _not _want to think about your tracker’s battery dying. If that happens, you’ll lose all your day’s data, and your workout will become moot.

That’s why we’ve scoured the market for the trackers with the longest lasting batteries! All of our top picks will last anywhere from 5 days to 18 months with just one charge!


If you’re a swimmer, your tracker is going to get wet; there’s no way around it. And outside the pool, jogging, biking, and other cardio activities are bound to make you sweat. So, you want a fitness tracker that can stand up to chlorine, salt, and sweat without cracking or snapping.

That’s why we made sure each of our picks are waterproof! You won’t have to stress about your strap or band getting eaten away by your hard work.

Frequently Asked Questions (FAQs)

Can I use my Heart Rate Monitor in fresh, salt, and chlorinated water?

Yes! As long as you make sure to clean your band or strap with fresh water after use, it’s sure to last you a lifetime!

Can I connect my Heart Rate Monitor to an app on my phone?

Yes! All of our top picks are Bluetooth connective!

Will my Heart Rate Monitor come with a warranty?

Yes, you can request a warranty for most of our top picks. A few also offer protection plans for an additional charge.

Are the chest straps comfortable for women?

Yes, they all stay in place and provide the ultimate level of comfort for women as well as men.

Will I be able to find a band or strap in my size and color preference?

Absolutely! Most of our top picks come in a range of colors and all are size adjustable for the perfect fit every time!

Are chest straps better than wristbands for tracking your heart rate?

Only slightly, and that’s because the chest strap is attached more tightly to your body. However, wristbands tend to be more versatile and convenient, so you could wear them for any workout all day and night.


If you’re dedicated to your workouts and your health, you know how important a heart rate monitor really is. You know how detrimental it can be not to track your heart rate and progress each time you jump into the water.

That’s why you came here. And we’re certain you found at least one monitor that fits your needs and price point. Our Top 10 Picks are all waterproof, so you know you’ll purchase something that won’t break as soon as it’s submerged. Plus, they can all connect to your devices, securing your data and allowing your workouts to improve over time!

So don’t waste any more days in the pool because you haven’t been able to track your progress. Take control of your workouts NOW and swim all the way to the healthy body you’ve always wanted!

Happy Fitnessing!
