Polar have confirmed to me that the M430 running watch has indeed got new innards. Obviously the optical HR gave away the fact that something had changed internally 😉 Well, the GPS chip has also been updated to the same one as used by the V800 (SiRFstar IV) – generally renowned for good GPS accuracy. Although equally as good GPS results have been recorded by me with the SiRFstar V on the Suunto SPARTAN SPORT.
- M460 u-blox 7
- M430 SiRFstar IV
- M450 u-blox 7
- M400 u-blox 7
Not confirmed in the same email but I believe the following to also be correct
- M600 – MediaTek MT2601 (Mediatek MT3333 is used by Garmin in the 920XT and I assume that same Mediatek chip is also in the Fenix 5X – mixed GPS performance)
- V800 – SiRFstarIV
