GPS is Ok for a quick check of speed, but I prefer to use the highway mile markers and a stop watch... 3600 divided by the time for your speed. I have seen to much variation between the GPS and the stop watch for speed.

Not that I don't trust a GPS for position, I love the 8 foot accuracy in bad weather, fog, 3 foot chop and a narrow cut. Beats the hell out of the Lorain.
