GPX VIEWER AND RECORDER CALIBRATION SETTINGS PLUS

I don't need that connected stuff, but the accuracy / reception is excellent, many, many annoyances in the UI have been fixed, and the bigger display alone for me was a reason to buy it. I am a big fan of the GPSmap 66s - finally, a real quantum leap in the GPSmap series. The device will miss the first or last height meters with bigger ascents / descents as well however, the relative error caused by this will be smaller the bigger the ascents / descents are. The total ascent is nearly correct if and only if your route only has big ascents / descents (e.g. For example, the elevation shown changes from 580 m to 585 m, but the total ascent only increases by 3 height meters. It probably misses the lowest elevation when going down and then immediately going up some height meters.Ģ) To make things worse, I am constantly observing that the device does not sum up the differences in elevation correctly. It's clear that the device won't show the correct total ascent if it is not even able to show the correct elevation. I haven't seen such misbehavior on other Garmin devices so far. Now, when having gone down such a descent completely and already having done the half of the following ascent, the elevation shown in the display still counts down. The ride I am talking of has quite a lot of small descents (for example, 10 height meters) which are immediately followed by small ascents of the same magnitude. I have done some investigation on the issue and found two problems:ġ) The altimeter itself is incredibly slow.

But the GPSmap 66s reports a total ascent of 213 height meters, which is an error of about 20%.

This is confirmed by several other GPS devices like the Garmin GPSmap 62s and the Oregon 600 both of them always show a total ascent of 250 hm plus / minus some deviation (lower than 8 height meters). That route happens to have a total ascent of nearly exactly 250 height meters. I know this route exceptionally well because I have ridden it over 1000 times with several other GPS devices and because I have manually computed the total ascent using precise paper maps. I use the device for mountain biking and have tested it several times while riding one of the smaller of my standard routes.

to be too high, I am having the opposite problem. While other people report the total ascent shown by the device or in Garmin Connect or Basecamp etc. I have decided to open a new thread for my problem because my problem is the opposite of what I have read so far (here and at other websites):
