I have noted that, during recent loop hikes, that the total descent always exceeds the total ascent. Not by much...25' - 75' but always the same way. Maybe that's within the margin of error but when I download the track, I can see that the elevation of the last point on the track is 25' - 75' lower than the 1st point (both points obviously recorded at exactly the same spot). So, the unit is accumulating ascent/descent properly but changing its elevation reading for a common spot.
I figure that this has something to do with calibration and/or settings.
Steps I normally take:
- Turn the unit on 10-15 minutes before I start the hike
- Calibrate the GPS to the elevation showing on two iPhone apps that are usually with 5' of each other.
- Hike
- Save Track
My altimeter settings:
- Auto-Calibration = On
- Barometer Mode = Variable
- Pressure Trending = Save When Power On
- Plot Type = Elevation/Distance
In addition, my track settings include:
- Record Method = Auto
- Recording Interval = Most Often
I don't mind if the elevation is wrong if it will be consistently wrong. In other words, give me same (or close) elevation reading at a common spot 3-4 hours apart.
I am wondering if anyone else has had this issue and, if so, what setting (or process) changes will fix this - thank you in advance.
