Refurbished (Excellent) - Fitbit Charge 6 Advanced Health and Fitness Tracker with Built-in GPS

Connect Charge 6 to your favorite compatible exercise machine and see your real-time heart rate directly on the display.

With over 40 exercise modes, you can set personal goals and get key workout stats for everything from daily runs and bike hikes to HIIT workouts, strength training and more.

Know when your body's ready for a workout or needs recovery so you can dial your exercise up or down.

Watching your heart rate during exercise lets you know when you're in fat burn, cardio or peak zones so you can adjust your effort to match your goals.

Active Zone Minutes tracks the time you spend in your target heart rate zones, so when you work out harder, you get credit. Workouts in cardio or peak zones earn you double the minutes.
