Garmin heart rate monitors compared
Garmin has announced a few days ago the budget friendly HRM-200 heart rate monitor. The company’ ‘s current range now consists of five different heart rate monitors. In this article we explain the differences between them.
The company may be known for sports watches, but it also dishes out GPS technology across a diverse range of markets, including aviation, marine, tracking and mobile apps. If you own one of its sports watches, you are probably aware that Garmin also makes heart rate chest straps.
Still better than wrist heart rate monitors
The value of such devices are that they are much more precise than something attached to your wrist. Garmin has a decent smartwatch heart rate sensor, but this still trails heart rate chest straps when it comes to accuracy. This is particularly evident with high intensity exercise such as HIIT – your data will sometimes lag. That is why many cyclists and runners like to attach a heart rate strap before heading out to exercise.

Interestingly, Garmin has not yet dished out anything that works from the mid or upper arm. We say interesting, because other companies have gone down this route. Polar is one such example with its OH1+ strap, but there are other examples. In our mind, it is just a matter of time before Garmin gets into this space.
Technical specs compared
For now, you have a choice of five Garmin heart rate chest straps. This includes HRM-Swim, HRM-Dual, HRM-Pro, HRM-Pro Plus and HRM-Fit.
There is also Garmin HRM-Run which can be picked up on some retail sites, along with HRM-Tri and HRM Dual. The first has been around since 2013, the second since 2015. So it’s safe to say they are packing older heart rate tech smarts. It is not a surprise, therefore, that both of these have been officially discontinued as they have been superseded by newer heart rate monitors. This is also the case with the last on this list, which saw the light of day in 2019.
You might be able to pick up some great discounts on these devices but know that you are running a risk as the product as not sold in Garmin’s store any more. Always best to buy the latest technology.
So it comes down to the other heart rate monitors. Here’s a table showing how their technical specs stack up.

HRM Dual vs Swim vs Pro vs Pro Plus: functionality compared
The HRM-Dual has been replaced by the HRM-200 as of the start of 2025. This updated model offers better accuracy, improved usability, and enhanced data security, making it a great budget-friendly option for reliable heart rate tracking. It supports encrypted data transmission for privacy and allows multiple device connections at once—up to three Bluetooth and unlimited ANT+—but doesn’t include advanced features like running dynamics or built-in storage.

The HRM-Pro and Pro-Plus are basically the same, with the only difference being how the battery is accessed. The Pro-Plus lets you twist the module to change the battery without needing any tools, which is a pretty nice touch. These models have extra features like Running Dynamics, run power support on compatible Garmin watches, and the ability to store data offline. They’re better suited for athletes who need more in-depth tracking and want to get into the nitty-gritty of their performance.

Then there’s the HRM-Swim, which is perfect for anyone who spends a lot of time in the water. The strap is designed to stay put while you swim, and it can store and forward your heart rate data to compatible devices. If you’re a swimmer, this one’s definitely a step up compared to the others.
A heart rate monitor for women
The HRM-Fit, priced at $150, stands out in Garmin’s product line for its focus on women’s fitness needs. It is uniquely designed to attach securely to medium to high support sports bras using three anchor points, accommodating various body types. This design ensures stability and comfort during intense workouts.
Functionally, the HRM-Fit is at the high-end. It supports advanced workout tracking, including metrics like vertical oscillations, ground contact time, and stride length, offering in-depth analysis of running form. The device is built for durability, with a battery life of up to one year based on daily one-hour usage, and features a tool-free door for easy battery replacement.
In comparison to other Garmin heart rate monitors, the HRM-Fit introduces a specialized approach. While models like the HRM-Tri and HRM-Run are tailored for triathletes and runners with specific metrics, the HRM-Fit is designed for women seeking a comfortable, reliable heart rate monitor that integrates effortlessly into their fitness routine.

The bottom line
Garmin has a nice selection of Garmin heart rate chest straps. Nothing that works from the upper or mid-arm just yet, but if you are serious about your running or cycling pursuits you will want one of these.
Top of the range are HRM-Pro, Pro-Plus and HRM-Fit for women. We suspect Garmin will discontinue the first soon so best to go for one of the latter two. The main benefit of going for the latest generation chest straps over the older ones is support for running dynamics, along with running power. The latter works on some smartwatches natively, on other Garmin watches by using the Garmin Connect IQ store solution.
If you want to save some cash, then HRM-200 and HRM-Swim are your options. There really isn’t any other reason to choose one of these two. The second costs a bit more than the first but has better water-proofing, onboard storage and swim tracking ability.
Whichever device you choose, take comfort in knowing it will spit out accurate heart rate stats and work seamlessly with your Garmin watch. The other option is to go for another manufacturer’s strap. These will also play nice with your Garmin timepiece. Our device of choice is the Polar OH1+ but there are other good ones.
