GPS totally unreliable and degrading even with GLONASS off
Late 2017 Spartan Sport now unusable, GPS drift is so far out to be unusable (10% at least). I have given up and gone and bought a Garmin. All my Garmin pals do not have this issue. I had the same with HR overestimating and have lost the will to try and solve it. I tried everything they suggested, updated just before run, wait for signal then wait some more. Suunto cant even be bothered to get their support documentation right suggesting to use “best” accuracy which does not even exist anymore in the menu. Come on Suunto. this is not good enough. I loved your ewatches but you lost me if I can’t rely on your GPS.
Have you ever tried to contact support? Maybe there is something defective.
In fact if you say " to use “best” accuracy which does not even exist anymore in the menu" maybe there’s something wrong.
Did you check power saving menu ?
Do you have the latest firmware ?
I use GPS only and I never face drift that can let me say that the watch is unusable … HR(if you meant OHR) it’s a different topic. It could simply not work for you.
