Suunto Heart Rate Belt - Heart Rate too high

Pasi80

Thank you. Mine seems to be black. I will take contact to Suunto suport

Hello everyone, I also have a Suunto heart rate belt with a black contact area (old version), and sometimes I experience the same issues with very high heart rate readings at the beginning, or it takes a long time before it starts providing any results. I always moisten the belt before exercising. Do you know if the grey version resolves these issues, or if it works better than the black one? Will they replace it through customer service, or do I need to purchase a new one directly? Thank you very much.

@fedequei @Pasi80 I do not know whether Suunto will replace old belts. However, the new one lasts for 1y to 1.5y for me with ~750h of exercise/year mostly with the belt. The belt will not last forever, the sensor is good for a long time as I am still using the sensor I bought with the Ambit. The newer belt is more robust, I used to buy belts about every 6 months.

@Pasi80 How old is your belt? I got my belt with the Spartan watch… I think it was too old to expect something when contacting the service

@Brad_Olwin I was not sure if my problems where caused by belt or by sensor… I bought a complete new set of both… but for less than in the Suunto shop…

@SuperFlo75 I bought both Suunto Vertical & Smart heart rate belt 5/2023. First problems came 6/2024 and after several maintenance “visit” the problem continue so they send me new product (both Suunto Vertical & Smart heart rate bealt).

I get my new warranty products about 8/2024 and the same problems start 12/2024 (4 monts after usage). 1/2025 the problem start to be every day when I went out to sport. And now I am going to send the products back to Suunto maintenance.

So frustrating

Luckily I still have my old Garmin Fenix 5x & garmin heart rate belt so I can use these while the Suunto maintenance.

@Pasi80 Sorry to read this… I think this should not happen! For me, my new belt is working fine now.

I have the same issue with my new HR Suunto belt and my S9PP.
I had the same with the Ambit 3 and my old belt, this was much worst though.
I always thought it was linked to dry skin and not enough sweat.
Strangely this does not happen when I ride my bike, only when running.

I have a similar issue with watch measurement (no extra heart rate monitor, only watch). During walks sometimes the heart rate suddenly starts showing a way too high. This looks like a watch issue to me, cause the only thing that fixes the problem is to take the watch off my wrist, wait for it to stop detecting the heart rate and then put the watch back on. Just changing how much the strap is tight doesn’t help at all. Example:

Hi.
All the watches I have used (Suunto, Garmin, Polar) cannot measure heart rate from the wrist properly.

Sometimes they succeed very well and sometimes very bad. Heart rate belt is the only way if you need/want exact reading.
