Suunto 9 OHR readings

@valdis830
Do you have 24/7 enabled ?

[Dimitrios Kanellopoulos]

this warmup issue is known. Unfortunately it is a vallencell side story (their FW).

I have communicated this right now to Suunto.

Please keep me posted on this thread if that also solves other people’s issues (the suggestion of @valdis830 )

[valdis830]

@sartoric I’ve never used 24/7

[valdis830]

@Dimitrios-Kanellopoulos It would be great if it were solution. For this I have shared my experience

[sartoric]

@valdis830
OK. It was just to check if you’ve seen improvements running the “instant” measurement additionally to 24/7

I have 24/7 enabled and usually “HR locking” takes (most of the times) less than 20 seconds and it is accurate enough from the beginning.

@sartoric I use 24/7 and it gives me good results specially during sleep. However, OHR for running really works bad for me, so I always use a belt. My watch is Spartan Sport WHR Baro.

It was funny one day that I forgot the belt and trained with OHR to find that I was supposedly warming up at 196bpm…

I tried this long ago and for me OHR just does not work well…unless I run on pavement and it is relatively flat. I found out at a conference that OHR is good to great if run on pavement and am not running steep hills. But on trails it just doesn’t work. This is variable as for some it works well. Hopefully more work will get it functioning better!

@Brad_Olwin same experience . I would add also treadmill.

However, I have tattoos and really slim arms

@valdis830 thanks a million for this!!
I gave it a try today (=while preparing for my run, I activated the heart rate reading from the main menu of the watch - I don’t use 24/7 hr), and see the difference below! Same track/pace/weather/absence of warmup.

Without your trick:

@jean-william-cousin Those look like pretty good readings!

[SlaSh]

Funny thing that Farmin acting the same, if you turn HR reading before workout it is way more accurate

[Dimitrios Kanellopoulos]

Keep the posts coming here people

@Dimitrios-Kanellopoulos tried it, didn’t work, still unrealistic hr for first 10 min.

More tricks to improve reading?

Use a chest strap
Suunto OHR has never worked for me (consistently 40bpm higher than actual). Chest strap fixes this for me. Can’t blame 'em, tattoos don’t play nice with OHR readings!

Hi,

Hi Guys,
Did you know that Suunto knows all these tips and tricks and there is whole blog on Suunto web site about this? And especially about warm-up before activity. Not only warm up for your body, but warm up for Heart Rate sensor as well

*If your watch shows inaccurate heart rate readings at the start of your exercises, a warm up may solve the issue:

Warm up for yourself: The quality of wrist-based HR measurement heavily depends on the blood flow to your arms and hands. A proper warm up for 10-15 minutes increases the blood flow and improves the quality of WHR readings.
AND
Warm up for the heart rate sensor: The sensor needs some time (several minutes) to lock on your heart rate. To give the sensor time to warm up, we recommend opening the exercise start screen already while getting ready for your workout (e.g. when changing clothes).*

I tested a Suunto 9 and a Spartan Sport WHR Baro for cycling. Both gave me bad OHR values. I used all tips and tricks given from Suunto.

Then I placed the watches on my right arm/wrist and was astonished to have usable values immediately. Not only once, but ongoing.

May be this is worth trying for other people too.

@pilleus this ?

this ?

Ah, okay, I didn’t read it before.

Yes, I can confirm this. The same 2 - 3 cm behind the wrist, the same width of the strap, just the other (right) arm.

[Dimitrios Kanellopoulos]

@pilleus Perhaps we need to make a poll about this ?
