Thread: eTrex 30 vs eTrex 20 -is a triaxial electronic compass really worth 40 € more?

thank you,

I had a look at the provided links and the review suggests for a N00b to get the 20.

but the One thing i (still) cannot not find out by searching around is if having a triaxial electronic compass does make any significant difference in the accuracy of the device?

I found this [Only registered and activated users can see links. ] which states "A triaxial compass means that users don't have to worry about holding the GPS receiver level. However, as noted by reviewers such as Rich Owings at GPSTracklog.com, the increase in convenience over a two-axis electronic compass comes at the small expense of a more complicated calibration process, and that must be performed each time the battery is changed"

Is the difference really significant or not "in real life" ?
