What is the accuracy of the watch
657557
Accuracy and Precision are not the same thing. The watch is precise to 1/100 of second, butthe how close it is to and actual 1/100 I do not have the answer for you. In other words, it reads to nearest 1/100 of second, however,whether that 1/100 of a second is exactly 0.001 seconds, that I do not know, it could be 0.00099 or 0.0011 seconds...not sure.

It measures in 1/100 sec to 40 minutes. The Quartz Crystal Accuracy is 0.1 sec/hr (accuracy may vary with shock, temperature or aging of crystal). The operating temperature is 14F to 138F (-10C to 59C)

the package states 1/100 sec to 40 min, 1 sec to 24 hours, I sell to trainers of national olympic teams and pre olimpic teams ordered specially by request I believe they know what they are ordering and have a reason for doing it, and it costs much more in Mexico , havent received any complaints of mal function either

RESOLUTION & ACCURACY LIMIT: The internal Quartz and IC controller LOOKS AT SWITCH CLOSURE every 1/256th of a second, so that nearest 1/100 is captured.ACTUAL ACCURACY: Tested and calibrated to be within 0.04 sec/hour for 12 months. Only shocks and aging of the quartz crystal affect this actual accuracy rating.

Hi Eric: I think it is quite accurate. i did a comparison with my Polar that uses a strap and they were consistently within +/- 2 bpm of each other, often matching exactly. I did find that the Polar seemed to fluctuate more, the MIO did not change readings as rapidly.

The watch keeps track of time and distance. I just do the math for speed. I never looked for a speed reading.

I believe so, however I don't rec a man this watch...doesn't work as well as advertised

You need to make sure it is tight enough on your wrist. If it's not, it won't read accurately.

I confirm using an old style, non digital Sphygmomanometer. That said, an exact comparison can never be made unless measurement made simultaneously - which isn't done. Even a reading with the Omron will differ when taken moments later. Consequently, accuracy is is considered OK when readings are consistently in the same range.

I know it shows average pace. And pretty sure it shows current pace. My son uses it for college cross country training and loves the watch. I will ask him about current pace when I see him.

You don't you have to leave the watch off for 20 minutes or so to get an accurate reading

I'm from Brazil and I use a Forerunner 10. The GPS is pretty accurate when used in open spaces.

I use it as a guide to see how active I've been. Room for error can be 15-25%. Mine has been very accurate with my workouts and strides.

I m not sure about the first 100 feet. But I m sure its not precise. By moving.the watch up and.down a bit it shows few feet changes.

Yes. I was told that it can be a little off if there are a lot of GPS watches in the area, but I have found it to be pretty accurate.

I can't answer your question. This was the watch I ordered but not the watch I received. I just returned it.

In theory, satellite triangulation is one of the most accurate way of fnding your position, not only in coordinates (Latitude and Longitude), but in altitudes as well. Altimeters in watches uses barometric sensors to measure air pressure to calculate altitude. I'm betting the 305 will give me the closest, if not accurate, altitude than the best barometer sensor watch in the market. Add the convenience of tracking and recording altitude, with your heart rate, time, pace, position and distance at the same time. Why settle for anything less?

No. It is definitely off by a hundred feet or 200 with each reading. My coworker and I are both fire fighter who bought the watch for elevation while doing weather on fires and from our GPS readings the elevation is approx. 100-200 ft off each time.

I have had no problems with mine. Accurate as far as I have been able to determine.

It wouldn't be 100% accurate, but close. My guess is the reading would be about 25-50% low.
