Looking For Reliable Heart Rate Data?
Our precision sensors maintain accuracy within ±1 BPM throughout the 30-240 BPM range, delivering clinical-grade heart rate monitoring during any activity. The advanced filtering technology effectively eliminates false readings caused by movement or perspiration that plague lesser monitors.
Tired Of Constantly Changing Batteries?
With an exceptional 1000-hour battery life, the BeltSafi H64 keeps going for years of regular use. One CR2032 battery provides approximately 2.5 years of workout data when used 4 times weekly for hour-long sessions. The intelligent power-saving mode extends battery life by automatically sleeping after 20 seconds of inactivity.
Want The Perfect Fit For Every Workout?
The ultra-lightweight design (just 43g total) combined with our adjustable elastic strap ensures maximum comfort during any activity. Properly sized for chest measurements between 64-110cm, the monitor maintains consistent skin contact without uncomfortable pressure or movement during exercise.
Built For Durability And Everyday Use
"After trying several HR monitors, the BeltSafi is by far the most reliable. No more signal dropouts during intense intervals, and the battery lasts forever. Worth every penny for serious athletes."
– Elly B., New York
