speedometer vs. GPS
Has anyone noticed a big gap between your boat speedometer and a GPS? I've noticed as much as a 10mph difference and was wondering which was more accurate? I am assuming the GPS since it is accurate on the road. It is an auto GPS (Nuvi 350) with the Garmin winnepesaukee map on it. Looking forward to hearing if anyone else has noticed this.
