Is there a GPS altimeter independent of barometric changes?

Yes it is but ,I don't know at the same place it write 260m and other time write 210m how can I fix it?

There is no GPS on the core. The barometer and altimeter are directly proportional. However variances in either are minimal. Don't try to look at the correlation when using them together. it is best to use them separate and you'll get a more accurate reading.

Don't know... haven't tried that yet... usually I'm looking for GPS coordinates based on maps and general topography... a lot of times when your in between high ridges being able to read a map; thus long/lat comes into play.... because the GPS can't pick up a signal..... both are good skills to have.

No. Does not give grids, lats, or longs. Battery only lasts for about four hours and is not a directional GPS. Distance, time, rate of travel, calories burned. Basically it would tell you that your slowly dying;-)

I do NOT believe there is. I am using their "Content Manager" to keep my content GPS updated and it's as slow as the first day I got it. Many times I've already passed a road and/or executed a turn by a couple of seconds before my position is actually recognized (and I am talking about suburbs with no building obstructions.) If you are reading this before purchase, do yourself a favor and consider something else.

Yes. It's under Mode > GPS. It can also show you a live compass, if needed.

I don't know about the TomTom, but the Garmin 255W will give you altitude information if you touch the vehicle icon on the map screen. This is also how to bookmark your location and see your longitude/latitude coordinates.

I think this is correct... Sensors: Light - YES Accelerometer - YES GPS - YES Compass - NO Gryoscope - YES Barometer - NO

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?

Not on the watch, but in the Run Details it shows the altitude, i guess from the GPS

This watch has an altimeter or an altitude meter which is an instrument used to measure the altitude of an object above a fixed level.ActiveLifeStore.com

I have not tried this... but you can't calibrate it to barometric pressure (aside from resetting your altitude to 0) so as the weather changes it will be less accurate. This also doesn't start recording altitude until you go up 50 feet from when you start recording. Furthermore the battery only lasts for 12 hours of continuous use. I think there are better altimeters for the price for your purposes.

I am NOT an expert by any means, however when I am in the tunnels in Boston I lose the GPS signal and it doesn't seem to be able to estimate where we are. The Garmin I had before could. I hope this helps!

It does have GPS capability. I've used it in Antarctica. Can be turned on and off in settings/location services.

Thanks for the post Laurent. That clears it up. Garmin should probably put that somewhere easy to find

This model does include altimeter functionality that uses barometric pressure for the measurement. That mean that weather changes can have an affect on the measurements. The functions include total climb and an altimeter profile for a given ride (a small graph of the changes during a ride). I'm in Houston so that chart is nearly always flat, but the features do seem to work as expected.

It gives Long-Lat position worldwide on land and sea but there is no hardware or software for maps. GPS location only.

Sorry. Got mixed up. Yes. There is altitude display. It works off barometric pressure.
