Specifically, the Garmin Fenix 7 vs Garmin Edge 520. The results were surprising for me because while older, the bike computer is so much larger I thought that would give it the edge (pun!)
In the end, the watch seems to be much better than the old 520. Yes it’s years ahead in tech but for someone that might not think the watch will do everything you need it to, I thought I would compare what I have on hand.
520 track
Fenix 7 track
Better charting on the Fenix 7 as well:
520 charts
Fenix 7 charts
The Fenix 7 also matches up with some nifty Garmin Connect things like MTB dynamics and Segments (image):
I believe the new Garmin devices like the 840 gives you the newer charts but besides the temp chart, I’m not sure I need to bother with the 520 anymore and I don’t have to spend the money on the 840… and that means weight savings!
