"The Fitbit Charge 6 sends your heart rate in real time to exercise machines that can use Bluetooth which means that treadmills, ellipticals, and stationary bikes can show your actual heart rate instead of using their often-unreliable handlebar sensors. This connection is important for interval training or heart rate zone workouts where you need exact feedback to keep up the right level of intensity. Fitbit changed the heart rate sensor array on the Charge 6 to make it more accurate during high-intensity movements."
"The built-in GPS records your pace, distance, and elevation data while you run, walk, or ride your bike outside. You don't need to bring your phone with you; the data will sync with the Fitbit app once you're back in Bluetooth range. You can leave your phone behind while you work out and still get all the information about your route for later analysis. The GPS receiver locks onto satellites quickly, unlike older fitness trackers that sometimes took a few minutes to get a signal."
Amazon extended Cyber Week deals into December with discounts on major brands, dropping the Fitbit Charge 6 to $99 from $159. The Charge 6 streams heart rate in real time to exercise machines over Bluetooth so treadmills, ellipticals, and bikes can display actual heart rate rather than handlebar sensors. The heart rate sensor array was revised to improve accuracy during high‑intensity movements after previous models sometimes lost tracking. The device includes built‑in GPS that records pace, distance, and elevation and syncs with the Fitbit app when back in Bluetooth range. Google Maps provides turn‑by‑turn directions on the wrist and Google Wallet enables tap‑to‑pay.
