Suunto M Series

The M Seriesof heart rate monitors are efficient and reasonably affordable. If your priority is heart rate tracking rather than performance tracking, this collection should cover all your needs.The design of these monitors is simple and discreet. Unfortunately, they’re no longer in production, probably because many Suunto watches have heart rate monitoring built-in.

This heart rate monitor hasn’t quite kept up with the times. While it runs on a lithium-ion battery, it has no connectivity options.

For privacy reasons, some people prefer self-contained gadgets that can’t connect to the internet. If that’s the case for you, you might enjoy using the M1 during your workouts. It’s a comfortable fit, and it provides accurate heart rate monitoring and calorie tracking.

The M2 comes with a chest strap, and people in cardiac rehab can use it for real-time heart rate monitoring.

The dual chest transmitter belt is also comfortable to wear. While this isn’t the best heart rate monitor Suunto has to offer, it has some interesting customization options.

Here is the heart rate monitor you should go for if you want to know the training load of your workout sessions during recovery. You can customize it to any sport and use it to plan ahead. Once again, you get a dual chest transmitter along with the monitor, as well as the so-called Movestick, which lets you store and upload exercise data.
