The Viavito Heart Rate Transmitter (SFIT-P-15123) is designed for fitness enthusiasts and cardio athletes who require precise, real-time heart rate monitoring during workouts. This device excels at providing consistent data for any piece of equipment compatible with 5.3kHz uncoded wireless signals, offering a reliable alternative to less accurate optical wrist sensors.
