I decided to upgrade from my Forerunner 620 and I could not be more pleased. Garmin has always made an exceptional product and they have even more amazing customer service to back it up. The Fenix 6S is just another example of an excellent product. I mainly purchased it to better understand my elevation gain/loss out on the trail along with the safety features. I’ve used other map functionalities on my phone out on trails and have been disappointed when I lose service but the Fenix map function is crazy accurate and gives me peace of mind out on trails and in remote areas. Thank you Garmin again for another AMAZING product! I could not be happier with my purchase!!!
