Memory: To be able to record the data of your previous training, you should need a heart rate monitor that has a good memory storage capacity. It is important to note that the lesser memory size can normally record 1 to 2 training sessions while heart rate monitors with large memory storage can record multiple heart rate data. The belt strap heart rate monitor and the strapless heart rate monitor both can accurately provide the user with accurate heart rate measurement which is impossible with manual method. The main advantage of the belt strap heart rate monitor on training is that the user can have an instant access on the status of the heart anytime he/she wishes to. But there is a great difference. Like what was said, the normal heart rate monitor can provide measurement whenever the user wishes to have it. The strapless heart rate monitor provides an on demand only heart rate measurement. Strapless heart rate monitor does not give a continuous heart rate data and the measurement is only given whenever needed. There are other sites that can give much lower priced heart rate monitor. In most cases, groups such as the police and fire departments could get discount heart rate monitor. A team with member that would get one each is also eligible for discount. The military could also get discounts on heart rate monitor. These two parts work hand in hand to give an accurate heart beat rating. But then most heart rate monitors use analog signal which is indeed accurate. But a more accurate technology is being capitalized by Timex to their heart rate monitor.
