Suunto Heart Rate Belt - Heart Rate too high

[Pasi80]

Hi.

Anybody still have problem with Suunto heart rate belt/strap?

I have Suunto Vertical and heart rate belt. Problems with heart rate monitoring (show totally wrong heart rate) start 2024 summer and finally Suunto changed both devices (vertical/belt).

4 months new watch/belt work correctly, but after that the same problems start again.

The problem have not gone away so next week I will send both (vertical/belt) to maintenance (warranty).

@Pasi80 actually I have no problems with SV and belt… but I bought a new one after the problems I had when I opened this thread

@Pasi80 does the belt have the grey color between connectors or black? The older belts (black around sensor connector) are not as robust and the connection degrades. A second issue if wearing a tech shirt and you don’t sweat enough static can build and affect reading HR. I always wet the belt under running water not just my skin. That keeps the belt wet enough until I sweat so static does not build. Even the new belts only last I to 1.5 years for me.

@SuperFlo75 okay… So after you bought a new one you haven’t got any problems (if I understand right)

[Pasi80]

@Brad_Olwin Can you send a picture so I can be sure what “area” you mean (gray or black)? I can check it later when I get back home.

Also I always wet (enought ) my heart rate belt before exercise. My Garmin Fenix 5 and Garmin heart rate belt working with no problems.

I have weared both SV + belt & Garmin Fenix 5 + belt -> Garmin gave correct pulse but Suunto is not…

@Brad_Olwin The new belt is the grey one, and the old was the black one. But the old belt was about 3 years old… I always make the belt wet before using it, and I wash it with clear water after using… but now, with the new one, everything is good

[SuperFlo75]

@Pasi80 yes, that‘s right

[SuperFlo75]

@Pasi80 I think he means this area…

@alebalbis same for me, exactly the same problem withe the HR spike at the beginninng. I have the belt with the grey area which seems to be the latest.

@SuperFlo75

It seems to be black… So it is old series. Need to take contact to Suunto suport. Thanks

@SuperFlo75

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.
