A worthy Upgrade!
on August 12, 2026
Posted by: Off Belay
I recently upgraded my garmin gear. I was an original fenix 3 HR owner with the sapphire glass. It served its life well and is still alive and fully functional! The main reason for upgrade was the battery life was deteriorating.
I debated for quite a while on which model 8 to go with and ultimately chose the AMOLED display in the same 51mm. I’m blown away with the performance and options this new piece of kit has to offer. It’s a learning curve with the new features and apps this can handle but it was a worthy upgrade.
To note. Most of my long thru hikes last a few weeks max. My runs are 10k in the woods. And I’m normally close to civilization or carry a charger. But I have yet to need to charge this thing until I get home. Even over 14 days while using the tracking when set up correctly I made it home wi the at least another 2 weeks of life left in the watch.

Dedicated Epix fan until I met the Fenix 51mm. Battery lasts for weeks and scores of adventures. Rugged and handsome.

Huge Step Up in Sleep & Recovery Insight
on July 30, 2026
Posted by: NewfieGuy
Upgraded from an 8-year-old Fenix 5 Pro Sapphire that still works perfectly, sapphire screen still pristine. That's Garmin quality for you, and it's why I'm pretty much a forever customer at this point. The Fenix 8's sensors are a big leap forward: sleep tracking is far more detailed, with real onset/wake accuracy instead of rough estimates, plus Body Battery, HRV, SpO₂, and restless moments working together to actually explain how I'm recovering. AMOLED display is gorgeous and easy to read anytime. This is my daily driver watch, and it's earned that spot.
