Pros and cons

According to our heart rate sensor expert
  • With the built-in accelerometer, you can also measure your running movements for even more insight into your training.
  • Thanks to the ANT+ connection, you can connect the sensor to multiple devices at once, like your sports watch and cyclocomputer.
  • The heart rate sensor is encoded to ensure that the signal from sports buddies won't interfere with the signals of your heart rate monitor.
  • The heart rate sensor doesn't have Bluetooth, so it can't be connected to your phone.

Description

The Garmin HRM-Tri Heart Rate Monitor Chest Strap Blue is made specifically for triathletes. The small and light design make the HRM-Tri a comfortable heart rate monitor that won't get in your way when you're running, swimming, and cycling. What makes the HRM-Tri special is its integrated accelerometer that's aimed at collecting different running data. The heart rate monitor not only measures your heart rate, but also your cadence, vertical movements of your upper body, and how long your feet are in contact with the ground while you're running. That means you can dive even deeper into your training data.


Note! Only a limited number of sports watches can register heart rate data while swimming, they are the Garmin Forerunner 920XT, Garmin Epix, and Garmin Fenix 3.

Lots of information!

  • You don't feel the band while exercising
  • Good signal
  • Easy to pair with the watch

This heart rate belt provides extensive information about your running sessions (even more extensive than the sports watch itself, in my case the Garmin Fenix 5X). Pairing to the watch is easy and only needs to be done once. As soon as you put on the band, your watch measures the heart rate via the band (and no longer via the wrist), this is automatic. During your running session, in addition to your heart rate, all kinds of values are measured, such as (among other things) ground contact time, the balance between your right and left foot, number of steps per minute and how much your body moves vertically. You can then find all this information in the Garmin app. I won't run again without this heart rate belt :)

Great heart rate sensor

I use this HRM dual in combination with a forerunner 245 and it works well together. I was a bit worried about the limited comfort of a band while running, but you hardly notice that you have it on. It fits well and is comfortable.
