Garmin Forerunner 45 manual

The Garmin Forerunner 45 is the GPS running watch with all the running-related features you need in a sleek, lightweight smartwatch. The screen can show up to three data fields at a time, and I found both distance and heart-rate tracking to be very accurate. There’s no question that Garmin packed an incredible number of features into the FR45, at least from an upgrade perspective over the FR35. The Garmin FR45 is packed to the brim with features.

Getting the most out of your Garmin requires some understanding of how to use it. That’s where having the owner’s manual comes in handy. With proper usage, there is less risk of damage, and you’ll learn how to get the most out of it.
