Garmin Edge 830 GPS

I have a Garmin Edge 830 GPS and it looks like it only shows steep grades as “>12%”. Is there a way we can get more detailed information about how steep the grades are once they go above 12%? Any other device that can give me this information?

Add the grade field to one of your data screens.


How do I do that? Sorry, I just got the device and I’m still trying to learn how to use it.

It in the manual under data screens / fields.
