Worth the effort
1 of 1 found this helpful Anyone who is a serious cyclist should consider this bike computer. While it takes a while to master,the 520 definitely is worth the effort. Things I like:
- Ability to arrange data screens to my liking.
- Seamlessly recognizes different sensors on different bikes, or different heart rate monitors
- Ability to add new sensors, such as power meter, electronic shifting, and rear radar, when, or if, I get these upgrades.
- Downloading Open Streets maps for my home area, and any area I travel to with my bike.
There is so much potential ability that this computer has that I haven't begun to use (i.e. Strava). It is a bit complicated to learn but it is worth the effort.

Nice change
Bought the Polar A300 gently used, but it came with a black band that was a little grungy. It was fine after cleaning up, but I wanted something a little less plain. The pink was not for me, and the yellow was a little too loud, so I settled on the gray. I only wish a red was available.
