I was wondering if Cateye still only recorded max speed in 0.5 mph increments? I liked that it always displayed current speed at the tenth of a mph but that max was halves. Likewise with Sigma, I wish it showed current speed to the tenth but I do like that max speed is in tenths. I suppose it's a trade off. I have a Cateye Mity 8 in my box of bike parts, but so far I like that Sigma has a more precise max speed. Current speed is always close enough because average speed is always properly reflected.
