    Default RE: Which is more accurate?

    I know quite a few sledders will talk about how fast they were able to get their sleds going and they often qualify their speed by saying it was the speed achieved by their GPS unit.

    As for myself in the car I have noticed that sometimes (in fact oftentimes) the speed registered on the speedometer is off a bit from the speed shown on the GPSr.

    Call me bored or just plain curious, but in your opinion what is more accurate most often (recognizing that if you have an EPE reading of 360 it may not be all that accurate and that snowmobiles may have some track spin giving a false speed reading for example) -- speedometers or GPSrs?

    well I drove a service truck that didn't have a working speedometer for almost a year, and I just used my GPS, never got pulled over. but if you really wanna know how fast your sled is going, just go flyin by a cop down the road, I'm sure he'll be glad to let you know.

    It's funny you brought this up...I had mine out today on the dash to check how close it was. From what I could, between looking at the GPSr, the spedomete and the road they were very close to being the same.

    THe gps and the speedometer are usually very close. I did notice a difference when I put bigger tires on the truck. SO now I use the gps for the spedometer

    I think either can be accurate, but you have to consider with the GPSr, if you are going up an incline, only your lateral speed is measured. So, if the road is not level, it will be off a certian percentage. also, the GPSr obtains speed from one point to another, so if you are turning slightly it will, again, determine your speed as if you were going in a straight line. Speedometers, on the other hand are unaffected by these issues.
