Brand new sense HR issue

[Lagsversa]

So loved my sense till I used the weight exercise function.   Have been using fitbits for years, charge, charge 2, versa and multiple ionics.   All had accurate HR strength training.   Today I lifted intensely for 1 hour 25 minutes and could barely get the heart rate up to 116.  Most of the time I was registering under far burn which also throws the calorie burn way off.    Device is 2 days old so don’t think a reboot is gonna be the answer.    I bought this as the replacement for my ionic recall.  Shame I liked it.   Guess it’s going into the return box.   Hate to do it cause I love fitbit but after the ionic debacle and now multiple posts about HR on the sense have to start to wonder about fitbit quality control.   We will see if fitbit has an answer but I think I will get the usual reboot the watch and follow articles for solutions answer.

This occurs, only when you are lifting?

Yes

Yes the heart rate is way low when I put it in lifting or any exercise mode.    I actually just went for a walk and while the watch automatically picked up the activity the heart rate was again way low compared to what my charge 2 and ionic would normally read.

Hi @Lagsversa - unfortunately as you see in the posts you can't rely on an accurate heart rate when moving but at rest it is pretty accurate and so it's not specific to your watch.

Well that’s kind of an issue when your using it as an activity tracker.   The movement and exercise part is kinda supposed to be fitbits wheelhouse.

All smart watches and fitness trackers use light to detect heart rate. Sense uses 6 independent optical channels, meaning it is more accurate than many others, at least theoretically. Mine is ok, accept for running intervals, but that is the same for all brands. My advice is to wear it a bit higher on your wrist, since lifting causes your wrist to move frequently. You need to make sure the back of the watch is touching the skin at all times, tight enough to prevent light leaking in from the sides and disrupt  the signal,while also ensuring it isn't strapped too tightly onto your wrist.

So I have now owned a charge, a charge2, versa, 2 ionics, and now a sense.   I lift 4/5 days a week for the last 5 years through all of those devices the heart rate has been accurate.   Yet the sense can’t seem to get it right.   I wear my sense in the same exact spot as I wore my

ionic.   I have tried going a little looser and higher and tighter to no avail.   The technology that you talk about is great if it works but this one doesn’t.   I lifted really heavy for over 1.5 hours today and could barely get my heart rate into day burn was below 108 for most of the time.   Additionally my heart rate is slower when walking.    The only thing this sense is getting right is my resting heart rate.    

what is the point of a fitness smart watch with exercise short cuts if they don’t get the heart rate some what close (also affects projected calorie burn).   

this is a known issue multiple people are having the same issue all through the forum.   After the ionic debacle you think they would make sure the new better product would be on point.   

might just be time to swallow the pill and go to garmin which will hurt cause I have been a loyal Fitbit customer for a very long time and have purchased many of their products to the tune of thousands of dollars.    

how can you be the pen ultimate fitness tracker company and yet continually get things wrong?
