Heart rate monitor question?

Question

Hi,

I'm interested in buying one heart rate monitor and I have a very basic newbie question.

What is the difference between analog and digital heart rate monitor?

Thanks

Answer 1

Analog transmission uses signals that are exact replicas of a sound wave or picture being transmitted. Digital transmission converts these signals into a binary code (0s and 1s).  Digital is the newer technology.

Analog transmitters are usually compatible with the cardio machines at the gym.  That's the main advantage of the analog system.

The main advantage of a digital transmitter is it less likely to run into interference from someone else's cardio machine, overhead power lines, or someone else's heart rate monitor.  Say for example you're running with your friend who also wears an analog heart rate monitor.  Sometimes the signals can cross, which means you're getting his data, and he's getting yours.  This is known as "Cross Talk."  With a digital monitor, the transmission gets encoded, so you're only getting your data.  The disadvantage is some digital systems aren't compatible with gym equipment.

All things equal, I would personally choose a digital system.  You can always wear your heart rate monitor watch to the gym and keep an eye on your heart rate that way, just as you would when you're out running the roads.

I will say, especially if you're a female (which I am guessing is the case from your avatar), the most important thing is to try on the chest strap.  Some are more comfortable than others.  I personally like the Polar straps better than Timex.

Hope this helps.
