I had the same problems as you... I didn't bought a new hr belt but i use it with the mobile and Strava and the results wasn't good as it must. My max is 180 and I had 200.... I did 3 series and only the first one was recorded well... second and third was rubishWith the previous firmware I had a lots of issues with the HR belt (Suunto smartbelt), tried changing the belt, battery etc. Nothing worked. Instead I bought a Wahoo Tickr (Ant+ and BLE) to use. Haven't had a single problem with the Tickr. Did a 12 hour ultra race last weekend and it worked perfect. Not sure where the problem is. Is it the Spartan or the belt? Or a combination? My Smartbelt did however work with my old Ambit 3 without a problem.
For those of you that have a problem with the Suunto HR belt. Do you have the same problems if you use it with another device (not a Spartan)? Eg, a phone app such as Movescount, Wahoo, Strava? That could rule out the HR belt as being faulty.
I think HR problem is combination of all factors like watch+FW+belt. My situation with SSU+Suunto betl:I had the same problems as you...

@Egika: Yes, I did it. And HR looks OK too. Therefore my belt works good with Ambit 3. But runing without watch does not make sense...My definitely opinion that new FW has a new bug with HR measurement and BT transmition. Fortunately I have new belt from my dealer and it does not have this problem...The Suunto belt also stores the HR information in case the watch is not nearby.
Would be interesting to see, if this has any effect on the recorded data?
@Sobul: can you test your bad setup in this way? Start the exercise, then remove the watch and only let it sync the HR from the belt at once at the end of the workout?
Very good article "how to clear HR belt": Heart Rate Monitor Not Working? That's Because It's DirtyStill getting nonsense HR readings. So unbelievably annoyed right now.
Hey @cageracer ... I'm the author of the article that Sobul linked to. Got that you cleaned it and swapped battery ... did you go nuts like I did and swab everything with rubbing alcohol as part of your cleaning routine?Thanks mate, I'll give it a go but I've already tried cleaning it and doing the battery thing.
