Is GPS + Glonass necessary?

I am receiving my 6x next week and was wondering if glonass is really necessary?  I have had numerous garmin watches (310xt, 910xt, VA, 935) and always have used just gps with smart recording most of the time. Transitioned to one second when I got the 935. 

Is glonass because of the sony chip and is anyone using just gps?

    GLONASS or Galileo give the watch satellites to choose from/use, which can be useful in the higher latitudes or under dense cover. Garmin seem to have 'tuned' the Sony GPS chipset to work better using GPS+GLONASS. However, testing I've done up here in New Zealand doesn't suggest much of a benefit. Best thing to do is to try and see. I think your F6X will come with GPS+GLONASS set by default.

    Thanks and I will test. Got the non sapphire version and depening on how I like the 6x I might end up getting the sapphire. If I think is too big I will probably end up getting the 6pro titanium.

    One thing that is impressive about the Sony chip is that you get the benefits of the 2nd constellation for almost no additional battery cost. So the question is why do you not want to use it? I only the5krunner was posting a lot is info on how glonass was making for worse accuracy on older watches. I've never found that to be the case. It did cost a bit of extra power. With the Sony chip that cost has been greatly reduced.

    Needs a little more battery. You can see that, if you change from gps to gps+glonass in the Power Mode settings of the used app.

    I would say you may get a little bit mor accuracy under tough conditions and the signal is more stable.

    *But maybe Sony and Garmin have done a good job and there is a better performance at all? 

     

    But answering your question: I would say under good conditions not necessary (except*), but because of the little more battery consumption...Give it a try and look, if you may get better results.
