Buyer’s Guide – Should I Go With Wrist or Chest Band Heart Monitors? What Else Should I Look For?

As always, we at All Things Waterproof try to give you, our friends, some tips, hints, and general guidance in choosing waterproof products. In this case, we’ve outlined a few tips to keep in mind when choosing the best in waterproof heart rate monitors.

Wrist or Chest Band Heart Monitors – Which One?

Our comparison table below shows the advantages and disadvantages of each category of heart rate monitors. i.e Wrist or Chest band monitors. Let’s have a look.

What Else Should I Look For?

Here are a few things you should look out for when buying waterproof heart rate monitor.


It’s in our nature, and our name, to always consider waterproofing as top priority in choosing any product. In most strenuous activities perspiration is quite likely to occur. With outdoor activities, exposure to moisture may be inevitable, incidents involving water are always a possibility, and of course, you may want to simply use your heart rate monitor for swimming or other water sports. With that said, always check the IP-rating and its subsequent meaning – which can be found here. In addition to IP-ratings, an equally important rating to check is the atmospheres, or ATM, rating. We’ll explain that further in this article.


Monitoring your heart rate is essential to maximizing your workout routine or exercise session, but equally as important is your comfort level. Naturally, the more comfortable you feel during a workout, the more you’ll be motivated, and subsequently, the more satisfying your workout experience will be.
Choosing a comfortable waterproof heart rate monitor that doesn’t require many adjustments once it’s attached is great for added comfort.


Compatibility can be considered an extension to comfort. Waterproof wrist or chest band monitors that can be wirelessly connected to your smartphone, tablet, or mobile device, are great for monitoring workout trends, progress, and data – especially real-time trackers. After all, what use is a workout routine in the pool if you can’t review the data.

 Cool Stuff

There are a number of additional features that will definitely make you feel like you’ve earned your keep in purchasing waterproof heart rate trackers. Things like:

1. Notifications that alert you of excessive heart rates.
3. Sleep trackers to monitor quality of sleep.
4. In-ear audio announcements of heart data.
5. Wrist monitors that double as watches and/or clocks.
6. Wireless connectivity and real-time data transmission.

8. Movement bars that prompt you to get going when you appear to be inactive.
9. Calories burned calculator or recorder.
10. Features that prevent or reduce outside interference.
11. Phone call, SMS, and social media notifications.

 ATM Rating

You may see this term, ATM-rating, pop up once or twice in the wonderful world of water pressure. But, what exactly does it mean, and what exactly does it refer to? Well, simply put, although certain devices such as; watches, smartphones, and media players – to name a few, may be able to withstand a certain level of water exposure, there’s a limit to the pressure these devices can withstand. The same can be said of waterproof heart rate monitors.

Yes, they are waterproof but can only withstand so much water pressure. Pressure tests are measured in ATMs, which stands for atmospheres, and we’ve created a table that simplifies the meaning behind these ATM ratings.


General care and preventative maintenance, similar to what you’d carry out on your typical waterproof devices, will always play a role in extending the lifespan of your waterproof heart rate monitor. Most ATM and IP tests are conducted in fresh water, so after salt-water use, it’s always a good idea to give your device a rinse and thoroughly dry with a clean, dry cloth.

There are many reasons you might want to invest in a waterproof heart rate monitor. Well, whatever the reason, we’ve given you the best the market has to offer, along with expert tips and hints in choosing the perfect heart rate monitor that suits your needs.
