Runners GPS

The Nuvi should give you a pretty accurate distance reading (within a quarter mile or so), but the speed will definitely be inaccurate.

You can see what I'm talking about if you look at your satellite page while stationary. The speed display will occasionally jump from 0mph to 5mph, etc.

Oh I don't know about that. I have had pretty good experience with speed and distance. The distance should be way less then a quarter of mile, more like 30 ft or less.

You've had accurate results while running/walking? Or while driving?

I know the GPS is accurate while driving, but I can't believe it would be accurate for running. Like I mentioned, the speed flucuates even when you are standing still.

An auto GPS used while walking/running is useful, but not as useful as a unit designed for walking.

One thing to remember while walking/running is that as you swing your arms, you are changing the orientation of the GPS, so it thinks you are changing direction. The second thing is that it only knows which way you are facing by tracking movement. If you stop and turn, it won't know that unless you start walking again. Most (?all?) of the "walking" units have a compass built in for this purpose.

I have used my 350 and 760 for geocaching occasionally, and it worked best in North Up view and making sure I hold the unit steady without swinging my arm.

If you are planning of a lot of use while walking, you would be better served with a unit designed for that.

The nuvi will work for that but be very inconvenient due to its size and shape. It will be hard for the Nuvi to figure out which direction you are going but you don't want it for that just speed and distance. The compass in the handheld units is just so that the unit knows which way North is so the display won't jump around. A GPS needs a speed of around 10 mph to accurately tell which direction you are traveling.

Thanks All, I'm going to try to use it to walk with tonight, and see how accurate it is. It is a bit bulk to have to carry around with you, even if it were accurate. I wonder how accurate the runner GPS's are?
