Why buy each?

Garmin Fenix

64GB storage and faster maps

Double the map storage of the Fenix 8, with 50% more RAM and 30% faster map panning for routable built-in maps.

AMOLED or Solar: choose your battery priority

AMOLED on every Fenix 9, with up to 29 days on the 51mm. The Fenix 9 Pro Solar reaches up to 57 days with solar charging for trips where charging is impossible.

New training tools

Stamina zones, expanded rucking with adjustable pack weight, and indoor rowing metrics join Garmin's existing training analytics, plus a 40m dive rating.

Garmin Forerunner 570

Multi-band GPS and Elevate Gen 5 sensor

L1+L5 dual-frequency GPS for precise tracking in cities and trails, paired with Garmin's most advanced heart rate sensor — adding skin temperature monitoring over the FR265.
