If you're looking for a nice fitness tracker for outdoor activities, then look no further than the Fitbit Charge 4.

It's a pretty versatile piece of fitness technology with a great battery life of up to 18 hours according to Fitbit's advertised claims. It also has some pretty great features that you won't find in the cheaper Garmin fitness trackers or the Apple Watch models.

This includes an integrated GPS chip inside to track the distance of your outdoor runs, bike rides and more. It also has a nifty feature called Active Zone Minutes, which allows you to set a target heart rate zone that will result in a buzz or vibration when you reach the zone.

It's also compatible with most smartphone apps including Strava, MapMyFitness, Runkeeper and more. In addition, it tracks your sleep and heart rate 24/7. It also has a built-in protein-iodine battery charger.

The Fitbit Charge 4 also has some great features unique to the Fitbit family of devices such as up to seven days battery life using a battery saving feature, 24/7 heart rate, automatic exercise detection and automatic sleep tracking.

A very nice fitness tracker, if you're in the market for something more upscale.
