I noticed a trend since coming back to the sport that windsurfers like cheap things that last forever

With this in mind Motion Mini has to be close to the top ranking
It ticks the box for price point plus accuracy, battery life, signal strength, wireless download and charging
Nobody is going to argue that the GW60 is at the bottom of the list due to reliability issues and battery life, but funny enough they are still selling plenty of them, I see them in the pro videos all the time, maybe these guys are not too worried if need to replace them each year
