The difference between the Fenix 6 and 6 pro is that the latter has 32GB storage capacity, Wi-Fi and map features which the former lacks.

• Design


Apparently, there’s no difference in the appearance of these two. The Fenix 6 has same design as the 6 pro except that the 6 pro weighs a bit more than the 6.

The colors also varies, the Fenix 6 is available in silver/black, black/red nylon, dark gray/black, titanium, titanium/orange while the 6pro is available in black/black (first color= case color, second color= strap color).


• Storage


The Fenix 6 pro comes with 32GB storage capacity compared to the Fenix 6 with just 64MB. As a result, you can enjoy your favorite preloaded tracks on the Fenix 6 pro which isn’t possible with the 6. This makes the Fenix 6 pro a great choice for those who want to take their music with them which can serve as motivation.


• Fitness Tracking


Just like all Garmin’s GPS smartwatches, the Fenix 6 pro and 6 are fitness focused and well equipped to offer you the most comprehensive fitness tracking experience. These two are no doubt some of the best GPS smartwatches on the market.

The Fenix 6 pro and 6 are well equipped to track your daily activities such as steps, calories, fitness age, distance, sleep monitoring, and all-day stress tracking.

Each of these three also features indoor gym activities such as indoor rowing, strength training, and cardio training, including in-depth training and planning analysis features that include training load, training effect and activity history on the watch.

These two also get running features such as running, treadmill running and trail running, plus heart rate sensor that tracks your heart rate variability and capable of showing your heart rate zones, max heart rate and recovery time to help you manage the intensity of your training so that you can achieve more fitness goals without breaking down.

The Fenix 6 pro and 6 have outdoor recreational features that include hiking, climbing, mountain biking, skiing, snowboarding, XC skiing, stand up paddleboarding, rowing, and jumpmaster. And cycling features such as biking, indoor biking, mountain biking, triathlon, including in-depth golf and swimming features.

Also available on these two is the body battery energy monitor feature that uses data from heart rate variability, stress, sleep, and other data to gauge when you’re ready to be active or when you may need to rest so that you train and achieve more without breaking down.

Also available is ClimbPro ascent planner with downloaded courses to help you see real-time information on your current and upcoming climbs, including gradient, distance and elevation gain.

The incident detection feature introduced to the Forerunner series is also available on the Fenix 6 pro and 6 which can help you get help when there’s an accidental fall. It sends your location to preset emergency contacts.

Also added to these two is swimming wrist-based heart rate tracking. With the Fenix 6 pro and 6, you can track your heart rate while swimming which can help you get a better insight into your swimming activities. This feature is new and exclusive to the Fenix 6 series for now.

Pulse Ox sensor introduced on the Fenix 5x plus is also available on the Fenix 6 series. The pulse ox sensor serves two functions; A. for altitude acclimation, where it can help you know when it’s not safe to continue climbing and B. sleep monitoring to help you see your quality of sleep. The Pulse ox sensor achieves these functions by monitoring how well your body absorbs oxygen.

However, the Fenix 6 pro with map which isn’t available on the 6 has features that come with the map functionality that the 6 lacks.

• Battery Life

Both the Fenix 6 pro and 6 have impressive long battery life that’ll see you through days on a single charge. Although these two have same estimated battery life, however, it’s pertinent to note that the Fenix 6 with fewer features will last a little longer than the Fenix 6 pro.

Garmin introduced new battery saver features that include the power modes which allow you to create custom battery saver modes, as well as the expedition mode featured on the MARQ series – an ultralow powered GPS reference that will keep the Fenix 6 pro and 6 going for weeks, and the battery saver mode that will keep both the Fenix 6 pro and 6 going for weeks.
