Beets BLU with chest strap ensures a continuous heart rate measurement with no interruption to exercise. The sensor captures the slightest electrical impulses and performs the most accurate heart rate readout due to ECG-based technology. Easy to use right out of the box, this heart rate monitor starts your heart rate reading in seconds and delivers lossless data transmission to your smartphone through the energy efficient Bluetooth Smart wireless protocol. The soft adjustable chest strap is very comfortable to wear. No more chafing or problems with the strap sliding down because the sensor is smaller and lighter than most other brands.
