Spartan Sport WHR Baro always reading HR too high at first few km while running
-
@vietpq I have issues that are worse than yours for OHR and at this time it works for some and not for others. I believe that Suunto is working with Valencel to make this work better. We just have to wait for future updates. I use the Smart Sensor when I need accurate HR.
-
@Brad_Olwin people reporting abnormalities even with suunto smart sensor… sometimes I feel like it is not an hr sensor itself, but something with algorithms.
-
@SlaSh Talking of issues…
Strangely enough, took my shiny new Suunto 9 for an inaugural run yesterday. Picture perfect HR from the built-in sensor on the first attempt, but GPS… Oh, GPS! Oh, gods! Suunto, no! Absolute worst I’ve seen even from much older devices. I’m fairly certain power saving wasn’t on, GPS quality was set to Best, and power profile was 24 hour… Running latest 2.1.64 firmware.
I was kind of surprised when it locked on GPS signal almost instantly – most watches, even “accustomed” to this location, take 15-20 seconds. Hopefully, tomorrow’s run is better.

@SlaSh @Brad_Olwin , I had a lots of problems with the smart band, HR spikes over 230 BPM, sudden variations, … Eventually I bought a new belt and everything is fine again (around 200 km with it). I got an A3 Vertical for more than a year and I never had issues with heart rate. I have a Sigma Rox with heart band that is made by the same people that makes the one for suunto (everything looks identical and have the same dimensions except for the different distance between the brackets for the sensor) and I still use the original belt with zero issues.
So, I’m inclined to belive that the original belt of my SSU was faulty.

I know this but if it was algorithms, it would occur for everyone. My Smartsensor is rock solid and I have not had any issue for a very long time. So it has to be a bit more complicated. It may depend on the sport profile or other odd combination of settings. As soon as I am done with my race next week I will start biking more and soon skiing. I did not have issues skiing last year but some reports are from folks biking so I will test that.

@NickK Can you post a link to this? My S9 is doing rather well for GPS.

@Brad_Olwin Not sure I can make just a few moves public, but here’s the tracks from Suunto 9 and Spartan Baro over the same segment of the run (and while we are at it, why not throw in V800 as a reference?):
Notice how Suunto 9 completely misses the turns and has me running through the middle of the boulevard in a wondering drunk type of fashion… I mean I do drink every now and then but I never work out while intoxicated. And I certainly don’t remember myself drunk enough to produce a track like that. Maybe I’m missing something in my life. Thank you, Suunto!
I’m not passing any judgments from a single run, yet – will run again on this route tomorrow and will do a trail on Sunday, but I’m somewhat concerned.
UPDATE: In the spirit of full disclosure: I did a second run today and now see a substantial improvement. I think it beats Baro’s tracks and most definitely the initial run:

Well, right now it happens almost every time, before starting the exercise when the GPS arrow and heart rate is on top of the watch screen HR says 80-90 for example, and then pushing the middle button to start the recording, HR says 130-150. When stopping the exercise immediately and starting everything is fine. A little annoying to be honest.
Maybe I have to flash the firmware to avoid that, but right now this workaround is just fine.@sartoric said in Spartan Sport WHR Baro always reading HR too high at first few km while running:
@jthomi
But that looks like an issue in “transposing” what is measured into numbers … or heart at full throttle

I have the same issue with my SSS WHR Baro watch. Most runs it doesn’t click in until about 1 mile in, no matter how much I leave it to link up to my HR (always have the solid HR symbol before setting off) or how much I warm up. Also has spikes during my run as well where it’ll jump to 200+, which makes the HR monitor completly ineffective for me. I’m finding myself not trusting it at all, which is a real shame.
Used plenty of other wrist based HR watches before, from TomTom, Fitbit and Garmin (which was the Fenix 3, so no issues around watch size either, this one is smaller!), plus used a chest belt previously, I know what my HR should be like. And the watch is on my wrist correctly, no light bleeding in, away from my wrist bone and I’ve tried everything mentioned here to get it to work right, it just won’t.
I’m getting close to sending it back as it’s not doing what it should do. I really do love the watch apart from this, which is a big disappointment. I can live with the Strava not syncing thing, using the SA app and manually uploading runs via a PC, but this on top of it as well is just one too many.
Does anyone know if Suunto could be fixing this at some point? It would be a real shame to send the watch back after 1 month.

OHR definetely needs some fix.
Im facing low HR values during the day and sometimes sensor freez which is not good. -
I think all need to know that oHR is very personal in terms of performance. I have seen @Dimitrios-Kanellopoulos in person with great oHR and me not so good. There are improvements coming but this is not an easy thing to do. Mine works great for walking and gym exercises like stretching. Running flats or uphill works well but not downhill. I also have the few minutes of way too high HR. This is helped if you select the sport start screen so HR is engaged but do not start. I did this while driving to my last run and did not get the high HR at the start.
But remember that different individuals will have different experiences.

This is a nice reading about this topic

@Brad_Olwin Interesting life hack. Will try tomorrow… What about GPS and foot pod?

I live/work at 5500 feet ~1600m in the Southwest (Boulder, CO) where there are few significant impediments to GPS so I rarely have GPS issues. I start my runs as soon as GPS locks on (usually a few seconds). Footpod, when I use one is Stryd and it is uncalibrated so the pace/distance/cadence all come from Stryd and not GPS. I typically use this only for intervals or when doing long races (Endurance mode) and I want better pace information.

Today, for the first time, I had this problem.
I started walking (fast but not so fast
) and after a while I noticed HR going up with no reason. Once touched the gauge max I stopped and paused the activity (checking if I was dying by heart attack ) put some air between the watch and the arm, then resumed … and started running, with HR back to normal.I don’t know if it has some relation with this or not, but once I paused the activity I’ve heard strange noises (like connection issue) in my BT earphones
-
I think the problem comes from GPS antenna, because when I start a indoor running, the problem does not happen
-
Any solution for this?
I always have an extreme peak at the beginning -

-
@vietpq same for me… Constantly have a spike to 200bpm on spartan trainer for first 10 minutes, even if I run 6min/km. After that settles down. Annoying, I think it’s fixable by firmware, but hard to know. On the upside, it makes me warm up more, like others here.

My WHR is just rubbish. During cycling or running, it stays for very long near my resting HR, then after maybe 15-20 minutes it shoots up but it’s far from anything accurate. During simple walking, it has sudden spikes. Comparing to the chest strap is not just a bit off, it’s totally wrong. It happened a few times I forgot my chest strap and had to rely on WRH ( SSWHR Baro ) and HR reading was just useless. I used to moan a lot about Fitbit Ionic device thinking that it cannot get any worse. I replaced it to SSWHR Baro to find out that indeed, it can
