Suunto ZoneSense

As far as I can remember, on my Vertical, when the optical heart rate is enabled and the watch loses the signal from the strap during an activity, it switches to the optical sensor.

No, it does not, unfortunately. I just double checked. Once you start an activity, there is no way to change sensors, HR or otherwise. I’ve had it happen a number of times where the battery on my external HR sensor dies or stops working for whatever reason. You’re then left with no HR data for the remainder of the activity. It definitely should fall back to the OHR, but doesn’t.

I tie this in with the general failing of how Suunto handles external sensors. Hopefully the ability to change sensors mid-activity will come along with the ability to have multiple sensors of the same type.

@James-Eastwood Will not work. My friend has a band like that. HRV only works when measured with their app. When connected to the watch, HRV measurement does not work.

James Eastwood

@Maryn @far-blue says he has one and it works. Now I don’t know what to believe

@duffman19 Yeah, I was wrong. I tested it myself yesterday. Thanks, guys — I was getting annoyed having to turn off wrist HR before every workout since it kept turning itself back on. I guess it’s better this way with ZoneSense anyway.

@James-Eastwood I can say something about this model:

HW9 doesnt work with zonesense despite the fact that it has HRV in the specifications.

PS. Sorry I thought you meant an optical sensor.

@Maryn But it’s still just an optical sensor, which ZoneSense doesn’t work with.

James Eastwood

Just to be crystal clear, it is this model.

It is not optical, it is not an arm band.

I was wrong!!! Garmin HRM-Pro will send two R-R streams to different watches. I tried this yesterday and both watches gave identical results. I started the Race S about 20 sec after the Vertical. Images are Vertical then Race S.

Tried again with the Coospo H6 but with with the wrist based HR disabled, and ZoneSense worked.

I will ensure that wrist HR is turned off for most activities by default.

No reason to turn off wrist HR! If paired to a belt and the belt is put on prior to opening the exercise in the watch the default is belt. I never turn off my OHR and always use a belt for running and ski touring.

Good to hear! Your original assertion was a bit confounding to me, as I could not deduce how one would be able to differentiate between the signals, and whether other companies had a similar problem. While the more ideal solution for me was “Brad was wrong,” I couldn’t make that claim not having experience with the Garmin. Happy you found the two streams to both give R-R info!

@raven My original answer was based on what I read some time ago, either here or somewhere else. I had to test to make sure and needed a new battery so finally got done.

A pity that Suunto’s own belt only support one channel, as even Garmin’s cheapest option the HRM DUAL supports two…
