Everything on the Garmin Fenix 6

The Fenix 6 comes in 3 sizes. The smallest version is the Fenix 6S. This watch has a 1.2-inch screen and 64MB of memory. Because of the smaller size, it's more suitable for people with narrow wrists. The medium Fenix 6 version has the same amount of memory, but a larger, 1.3-inch screen. The Fenix 6X only comes in a PRO version, and its 1.4-inch screen makes it the biggest out of the 3. It has a lot more memory, 32GB to be exact. It also has a longer battery life, lasting up to 21 days in smartwatch mode and 60 hours in GPS mode.

The Fenix 6 watches are suitable for performance-focused athletes. This is because of the advanced performance readings. For example, the watch measures the running dynamics you use to run more efficiently. It also measures your VO2 max, which gives an idea of how fit you are. This reading is adjusted to heat and height to make it more accurate. The Fenix 6 gives you a recovery advice after a tough workout, so you don't overexert yourself.

All Garmin Fenix 6 watches have Power Manager. This function indicates the effect of the chosen settings on the battery life in hours. You can extend the battery life by turning off any functions you don't need. The watches also have an Expedition mode that uses the GPS minimally, so they'll last 20, 28, or 46 days, depending on the model. This also makes the watches suitable for outdoor adventures.

As expected, the entire Fenix 6 series has Garmin Pay for contactless payments. That means you don't need to bring your wallet on your workouts to buy a bottle of water or a cup of coffee when you need it. Keep in mind that Garmin Pay doesn't work with every bank.

The Pulse Ox sensor measures your oxygen saturation. This is the amount of oxygen in your blood. It indicates how your body responds when training at high altitudes. Think of cycling in the mountains, skiing, or rock climbing. On the Fenix 6, you can view a graph of your blood's saturation during climbs and descents.

Every Fenix 6 also comes in a more extensive PRO version. One of the differences is that PRO watches navigate using a map instead of only showing a line. The PRO version also has Trendline Popularity Routing, which means the watch determines a route for you based on the data of other Garmin users. That way, the watch can show popular routes that follow roads and natural paths as well. With PacePro, the PRO version helps you reach your goal pace during climbs and descents as well.
