How accurate is the Barometric Altimeter on this device?
1242029
I haven't used the altimeter readings too often, but checking against the topo map of where I live, it seemed to be within 20 feet without calibration, and within 10 after calibration (for that day)

I have the dial model and the temperature on it is totally accurate. I tested it with a proper thermometer. It is excellent

i am using meters fromwww.simmeters.com. they have the full set of a10c meters available on their webstore. i will be buying the wet compass from simkits.com

Yes, we use in aviation and its very accurate!I saw some app to walk and you can conect this device.Good luck.

Tom and Aaron are correct. Great unit that comes as a complete kit and works very well with any iOS device or a PC. I get about 1 meter accuracy with it compared to the 65 meter accuracy I get with the built in iPad GPS.

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

As long as it reads 300 to 400 outside it gives me confidence that it is fairly accurate. And it Alway has stayed in that margin outside. In a dark room you can see the infa red pulse every few seconds and seam to adjust corispodingly. Hope that helps.

The compass only seems to function for a 5 degree range of looking "up hill or down hill". Any more elevation than that and my Barska compass seems to "drag" and be very inaccurate.

My Legend HCx Garmin eTrex Legend HCx Personal Navigator worked great in the plane as long as I was quite close to the window. A Cx might not. My GPS said we were a few thousand feet higher than the captain said we were but maybe he was wrong! It tracked very well. I could look down at a town and recognize it from the map on the gps as we flew over. Very cool!! On the ground my elevation is quite accurate with my topo maps loaded. IF you have the Vista you may need to calibrate it to the known elevation and air pressure any time the pressure changes much. I don't know this for sure as I haven't read the manual but other altimeters that use pressure need to be calibrated.

Ive had this range finder for 3 years now. It is deadly accurate. Make sure your hitting the pin and its dead on. If the GPS next to you gives a different reading it is wrong. I have had that come up several times. I trust the laser in my hand over the satellite 12000 miles away. If I check GPS locator on my smartphone its never dead on. Misses by 30 feet (10 yards) sometimes.

Not as accurate as a gps type pedometer would be, because I imagine hiking involves strides that are not of a consistent length (like when you're climbing over logs.) So it might not be super accurate for distance. I have worn it hiking, and it does provide some useful info. If you are mostly on easy trails, not too much climbing and scrambling, I think it would be fine. Oh and I wear mine daily and it shows no signs of breaking. I lost my first one, but I had it for over a year. Second one for many months now. Still love it.

GPS itself isn't guaranteed to be more accurate than 7.8 meters worse case for consumer use. 7.8 meters is getting close to 25 feet.

Jack, I emailed the manufacture and they sent some instructions. This is what they sent to me: To set your barometer please follow these instructions: 1. Get an accurate barametric pressure reading from your weather service or airport. 2. Turn the adjustment screw, if you need to, to the barometer to the reading of your weather station. 3. There are two needles. One that automatically follows the changes in atmospheric pressure while the other one remains fixed until moved by hand. 4. Set the movable dail by hand to coincide with the needle marking the current pressure. 5. Watch for the needle that follows the pressure changes to move up or down from that fixed point. Tap the barometer lightly before taking the reading. 6. Compare the readings to the weather reports and other reports of barometric pressures in your area to confirm the accuracy of your unit. I hope this helps!

Yes, in as much as the built in altimeter is accurate. This is old tech, newer companies offer better products an besides, much, much more importantly other companies may offer better support. From first hand experience, Fitbit customer service is atrocious, and that is very generous!!

Forerunner 305 doesn't have a barometric altimeter, but it's still able to "approximate" the elevation/grade. As CompExpert mentioned, it does do the job, but it's flaky. If elevation/grade matters to you a lot you're better off with the Edge unit that has a barometric altimeter; however you won't be able to wear the Edge on your wrist.

I doubt that it is "accurate" in terms of being calibrated to any significant extent. I just line the up the disk to where I want it and it is very close to my floor pumps reading. I just use it to finish my ride if I get a flat. If I'm within 10 psi I'm happy enough to get home.

As far as I know, no, A B C, altimeter, barometric, compass. I was debating on this watch vs. a GPS watch, but I wouldn't use the GPS watch as much. I hope this helps&#128512;
