The chest belt of my 2004 Ciclosport broke in half, so I had to decide what heart rate monitor to get. I choose the Polar FT1 with just one button and love it already.
Press the button once and you’re off. That simple. My old HR monitor had four buttons and I needed to press at least two to start.
The screen displays my heart rate. When I want to change the display to the time or stopwatch all I have to do is hold the watch close to the chest belt. This is called HeartTouch and works very well. No more frustration of pressing the wrong button.
Entering data with just one button is a bit cumbersome, but doable. Ask yourself how often you change time or heart rate zones?
