I also have a digital blood-pressure monitor, but being an athlete, I have a slow resting pulse rate, and I find the digital monitor to give erratic readings. It took some practice to learn to use a sphygmomanometer with a stethoscope (learning to use the stethoscope of monitor my pulse was the difficult part), but now that I've mastered the technique, I get blood-pressure readings at home that track well with the readings in my doctor's office.
