How accurate is the speed/distance measurement?

I've used the first generation Nike SDM unit(which is an accelerometer) with much success over streets, trails, and races. Over a marathon it was within 10 feet over the entire distance. So I plan to check this out, first without purchasing the shoes and just strapping the accelerometer to my shoe. Once calibrated, I expect it to behave the same as my SDM. Once you have a nano it is a pretty inexpensive running tool. I picked up a 1gb nano brand new on craigslist (sf) for $100. I will purchase one tomorrow and try it out over the weekend.

I am not sure I can help you with the specifics mine was very simple to set up ... check to make sure you have the sensor and the spoke magnet in the right alignment. That is where your speed reading will come from and without that correct you can't get a distance traveled reading. Make sure that the sensor on the fork is facing the correct way. If I remember correctly it looks like a little dot and that is where the magnet needs to be passing in front of for the unit to give you a speed. Also make sure the distance from magnet to sensor is not too far away. Hope this helps

NO! Any tracking would be totally inaccurate. It would only respond to motion of your legs and arms. If you're coasting, the mileage indicator would not record it. You'll need an odometer for that. jcp

In my case the gauge was accurate when I compared it with my pencil type tire gauge. I have not used the unit much to find out how reliable it is. It has been consistent so far.

This was a gift for my husband. It was used mostly on a Florida beach. He didn't think that this was an adequate measure of his speed or distance. It was calibrated by what he thought his speed was. He also said that if he stopped along the way he got the same result as continuous walking. He no longer used this item.

Usually quite accurate. If you can get it to update the maps and software. When it does make an error, you may wind up down a narrow dead-end road or 15 miles out in the middle of nowhere. The second time I tried to update mine, it failed to update and crashed and became useless. I bought a Garmin.

flat out we havent a clue how accurate the number is. but the one I bought is consistant. the calibration knob is used to get your SWR its not used to calibrate the meter

Cable is 3ft long, and regarding "motorized" bike/trike use, from the manual..Speedometer: ...The range of measurement is from 0 to 99 KM/hr (0-99 M/hr) and accuracy is +/- 0.5 KM/hr (M/hr)Presumably, if you're going under 100 MPH/KPH it should be able to measure without issue.

Unknown. Mine is also...reviews prior to my purchase several years ago lamented this as well as it not displaying in mph.Engineering guess is an error in the algorithm...do not know what this says about any location accuracy, but then I didn't get it for that.

Steps taken is as accurate as any similar pedometer. As for distance traveled, it gives the average distance. When it's on bike mode it uses the phones GPS.

I would say it is fairly accurate. I compared it to my more expensive Radio Shack and the numbers are very comparable.

I think it gives an accurate reading on how far the ball flies ,, the readings with the driver estimate roll so not as acurate

It is variable speed. I don't know how I would measure whether it goes to or beyond the specified speeds.

Yes it always updates speed readings quickly even at WOT but I haven't checked it against another gps for accuracy.

Thanks for the help. I've set the tracking to "auto least often" and that seems to nail the distance pretty well. Did a measured 2.6 mile hike out and back through some fairly heavy cover and got 2.63 one way and 2.65 the other. Close enough. Funny though, Garmin "admitted" this was an accuracy problem. Told me the fix was downloadable on their site, with the Web Updater, but I've decided not to mess with it. Don't want their gremlins crawling around inside unless I have no choice.

I thought so. The mph it's always displayed and the various modes are in smaller font. If your working on keeping a pace or working up to one, this gives you an accurate measure. If you don't need cadence there are cheaper models. For another 10 bucks this is a good feature and this is one of the cheapest computers with cadence. Add solid product too.

It is important to remember that this unit works best when the moving object is coming directly (as directly as possible) toward it. So, if you're at an angle to the ball travel line I don't believe it is going to be as accurate as coming directly toward the unit.
