Blaze GPS accurate?

[Danianya81]

I've recently bought a blaze while my friend has the surge. On runs we can be up to half a mile difference in length. I'm attached to the gps on my phone. Does anyone know which is more accurate? I thought by linking to my phone the accuracy would be assured now I'm wondering if I bought the wrong one

Morning

Just upgraded to a blaze from a charge hr. Using my phone GPS (samsung s5) is fine with me. However when i run with my friend who has a surge her runs seem to be up to half a mile shorter than mine over a 6 mile run. I have also compared to map my run and her phone seems to be accurate where as mine isn't. my location is turned on, my phone is showing at least three green bars when it connects. However on the runs together our paces normally match and our steps are always within a couple of hundred of each other as our calories burned - we are similar in height and build.

 has anyone else experienced bad gps when connecting or is there a magic setting i've missed? Love love love the blaze otherwise but if the milage and pace is off its just no good to me. Thanks all

I'm also having this issue and have been testing with various phone apps running at the same time as Blaze connected to my phone GPS.

The GPS tracking for the apps are different to that of the Blaze, and they seem more accurate that the blaze.

According to my maps on Blaze, i was all across the coastline last weekend, I wasn't aware that I did any swimming, just walking the coastline.

Strave and Endomundo were able to keep track of me, not the Blaze!

I'm very disappointed with this.

Hard to say why the Blaze struggles at times, at first I thought it was GPS track smoothing (e.g. Strava, Runkeeper, Endomondo, etc) as the app vendors figured this out years ago and Fitbit is new at it. However now I'm starting to wonder if its a Bluetooth connectivity issue, as that would also explain why its not consistent. Somewhat of a mystery, only Fitbit knows for sure.

My Blaze will show the map of where I've run. Now i run on an oval track. However the map shows me going in zigzag zags, a starting point in a nearby neighborhood, all kinds of crazy patterns that are not the oval I ran. Irritatingly inaccurate!

I also find that the Blaze reports between 0.75 and 1.5 miles shorter than both my bike computer and MapMyFitness. MapMyFitness using the GPS on the same phone and the bike computer measuring from wheel revolutions are normally within 0.1 miles of each other.

Hello all, I hope you are doing fine.  I would like to know if you keep having problems with your Blaze accuracy? If you do, I recommend restarting your trackers. Also, I recommend checking the Things you can do to make the Blaze more accurate post of our friend @bcalvanese where you will be able to find a really great tips.
