The speed "resolution" on the APEX Pro and VERTIX is approximately 5 cm/s. This is much lower than all other comparable devices and has the effect that distinct speeds are seperated by roughly 0.1 knots.
This is not a feature of the Garmin Fenix 6 which uses the same (or similar) Sony chip and has a resolution of 1 cm/s.
For the sport of speedsurfing, competitions can be won by less than 0.1 knots and the speed resolution is therefore very important. This specific topic can also be referred to as "quantization issues" and has been written up in detail in my "speed resolution" article.
