Powerful GPS sport watch features

Because both are multi-sport GPS tracking watches, there are many features in common between the Garmin Fenix 5 and the Garmin Fenix 3 HR. First and foremost is the GPS tracking function. These watches can be used to track distance, pace, and time for activities such as running, hiking, swimming, cycling, skiing, and more. The GPS precision creates a "backtrack" feature, which can help navigate you back to your starting point once you turn around on your route.

Because both watches have the ability to track multiple sports, they are great for triathlons and other multi-sport events. In addition, both watches boast a great battery life, making them ideal choices for events such as ultra marathons that may take many hours to complete.

Further, both watches include wrist-based heart rate monitoring. These watches measure the user’s heart rate constantly, which means they are able to give accurate calorie burn information for activities. In fact, these watches can be worn at all times like a regular watch and provide daily user data such as step count and total calories burned.

Fenix Features Compared

As previously discussed, these two sport watches serve the same basic functions and have several features in common. However, there are some distinctions between the two models.

In general, the features of the Garmin Fenix 5 expand upon and go beyond the features offered by the Garmin Fenix 3 HR (Amazon). First of all, the screen resolution is better on the Fenix 5. The screen is also able to display colors more vividly, offering a 64-bit color display over the Fenix 3 HR’s 16-bit color display. This makes the screen more pleasant to look at and easier to read in direct sunlight.

The Fenix 5 is also sleeker (Amazon); the dimensions are slightly smaller, and it sits closer to the wrist than the Fenix 3 HR. In the Fenix 3 HR, the wrist-based heart rate monitor added noticeable bulk. With the Fenix 5, the design has been slimmed down, and the heart rate monitor is less noticeable.​

The Fenix 5 is able to track more sports than the Fenix 3 HR. While both watches offer a huge number of sports for tracking, the Fenix 5 allows the user to be even more specific than before. For example, the Fenix 5 can differentiate between treadmill running and indoor track running. This was combined into one running option on the Fenix 3 HR. Other sports, like snowboarding and skiing, have been further differentiated as well.​

Overall, when it comes to the Garmin Fenix 5 vs Fenix 3 HR, the Fenix 5’s many added and expanded features have the upper hand.​
