67i Yesterday I went on a 9.7 km walk. I recorded the walk with the 67i and the walk was only 6km. In Basecamp the « track » seemed to be in straight lines. The two other recordings with an iphone « GPX Tracker » application and the Canon GPS (GP-E2) were both 9.7 km. The traces were much more zigzag ! I do not understand perhaps what parameters to SET in the RECORDING function. Moreover, I find the 67i manual incomplete and confusing.
