RECENT In-Depth Review Of Production-Level Garmin Forerunner 645.
I have read his reviews before. They are detailed BUT, for whatever reason he doesn’t seem to run into the problems that the rest of us do. Hhmmm.
I skimmed through this mainly for affirmation of my current take on the Forerunner 645. That it does.
Have a look through it. You might learn something. If nothing else the pictures of the various screens are worth seeing.
