HRM 2?

@Egika Yes but Joaquin has said that if you use the old belt with the new sensor you do not have the same accuracy…
I have been testing all combinations and could definitely not spot any difference in the belt used - given that it sits in the correct position.
The new belt is wider and has some more silicone printing to avoid slipping. It also has a nice logo print. But if the old belt is not worn out, it delivers the same data (it actually only serves as a contact of the sesor to the skin) as the new one. -
@Egika Glad to hear its wider and has these silicone strips. The old one is moving up and down during the run - at least for me.
Where can I place my order
-
@snow Thank you! I am not sure if I am as super-excited as Joaquin is, but at least very excited.
The bigger battery is another plus and the price is absolutely reasonable with 99€. Can’t wait to get one. -
@egika I own a SV1 and I’m interested in the diferent metrics that this sensor gives but not the SV1. I understand that the Suunto+ app mentioned by Joaquin is to see the real time data in the watch but I couldn’t find it yet. If I buy the new sensor, and the app is not availiable yet, how are the new metrics shown? Will they be shown in the activity summary?
Thanks.

@Tieutieu Yes, I couldn’t order it from Suunto too, but a local CZ store has it, and I’ve already ordered it. I’m really looking forward to it.

Well, after some questions to Joaquin, as for now, the new metrics aren’t compatible with the SV1, it seems they will be. Only Race1 and newer watches can show them.

@martintrail It’s online now on suunto’s website

[edit : error message saying it can’t be shipped to France
I guess I need to wait ! ] -
@Tieutieu ditto! (.it)
-
@Tieutieu same in Austria - currently not shipping to Austria (from suunto.com/de-at)
-
@Tieutieu same with Sweden

-
@GratefulDeadpan Yeah… I was flabbergasted! And a bit irritated.
-
@stefan-t. @gratefuldeadpan @snow … F5 is my new best frien again !

I’ll add here too, I have used the old belt with the new sensor with no issues. For me personally the old belt is more comfortable so I prefer the old belt to the new one.

I asked the Google Neural Network. Just typed in “SHRM2” and got as a starting paragraph:
“The Suunto Smart Heart Rate Belt 2 (SHRM2) is an advanced ECG heart rate monitor featuring Bluetooth 5.4 connectivity and ZoneSense optimization, with pre-orders opening on September 8, 2026, and global availability starting September 15, 2026, at a recommended retail price of AUD 249.”
Don’t know where the data comes from (global availability).
