Key features and benefits Fabrics and adaptive electrodes are designed to respond to your heart's electrical signals, delivering accurate and stable heart rate data during activity. Compatible with different heart rate sensors including ANT, Bluetooth 4.0, and 5.3K, enabling seamless use with a wide range of devices. Chest strap made from material provides secure, close contact to the chest for reliable readings. Comfortable and adjustable elastic strap allows a snug fit for varying body sizes and activity levels. Why you need this Accurate heart rate readings help you train more effectively by targeting precise intensity zones and monitoring recovery. Flexible compatibility minimizes the need to existing sensors or receivers, simplifying setup across devices. A secure fit with a comfortable strap reduces signal loss during movement and long sessions. What makes it stand out A combination of optimized fabrics and adaptive electrodes for better signal capture. Broad sensor compatibility (ANT, Bluetooth 4.0, 5.3K) supports diverse equipment and apps. chest strap material paired with an adjustable, comfortable fit for extended wear. Use scenarios Indoor gym interval training: Pair with ANT or Bluetooth devices to monitor realtime heart rate and maintain target zones during intensity intervals. Outdoor running or cycling: Secure, close contact ensures stable heart rate readings through sweat and movement across variable conditions. Daily activity and endurance sessions: Wear comfortably for extended periods to track heart rate trends, performance, and recovery over time.
