Does this work with Coros Apex 42mm watch?

I am confused why you would need an external heart monitor when the Coros Apex watch has a built-in heart rate monitor with the exact same technology as the COOSPO HR monitor. Nonetheless, the Coros does accept Bluetooth accessories and Coros sells their own compatible peripheral HR monitor, so the COOSPO would work with it.

does this detect pvc?

What is the meaning of PVC? It was an armband that detect real-time heart rate beat, thank you.

Is there a way to disable the buzzing when your HR hits 180+? This is a pretty useless feature.

In Coosporide app, on the top of the riding page, there is a setting button, click it and you can close the warning function of the armband, thank you.
