我的是没有气压表的101
http://www.backpackinglight.com/ ... 1897&startat=20
看这个人说的貌似401的功能就是这么设计的
I chose the 301 over the 401 because I wanted to track things based on GPS altitude and NOT barometric altitude.
这个人说问过garmin,401的高度的确来自气压表而不是GPS

After I bought this, I discovered that the ONLY altitude that it will display is from the barometer. It will NOT display an altitude using the GPS fix. I took it back and got the Garmin 301.
The altitude from a barometer is useless if not calibrated daily, which is not possible on longer trips. We can not get a pressure reading, and often we are on glaciers where the maps and altitudes are no longer correct. Even on shorter, day trips you need to remember to calibrate the unit before heading off.
I called Garmin and they agreed that the unit does not provide an altitude based on the GPS signal." |
