What with a increasing enthusiasm for tighter speed monitoring on our roads and the inevitable inaccuracy of a T9 cable-driven speedo in a Morgan, I'm thinking it might be wise to join the ranks of those who have fitted a GPS Speedo, especially with a Scotland trip coming up.
But a quick perusal of Amazon seems to show (a) a bewildering variety and (b) that they seem to be pretty large, so over to you guys.
I want something large enough that I can see the digits at speed (obvs), but small enough to mount in the eyeline of a Trad without obscuring too much. Extra bonus points if it can do some trip logging, even more bonus points if you can download the data for analysis.
TIA
