For any dgree of serious training is far too easy to either go off too fast, and then struggle through at a plod, or plod at the start and do a final dash for the line in the last 5 minutes... with too much energy left in the tank..... A heart rate monitor will help you to manage a constant effort throughout a training session, thus vastly improving you total training time and quality.
Your heart rate is one of the most useful indicators of fitness level - how quickly you recover and also when comparing one session against another. ie. same distance, same time, lower average HR = improved fitness
All of the HRM's we sell receive signals from the heart which are transmitted via a chest belt to the base unit. This type of HRM is the most accurate. Look out for digital transmision. This prevent interference from other other HRM signals, especially useful when training or racing in a group.
