Summary: Monitor heart rate while working out or doing strenuous hiking. I'd never used one before, and was relieved to find that the body band is comfortable even when I'm active and sweating, and the numbers are large and easy to read at a quick glance.
Summary: Exactly what I needed for my recovery from a quadruple coronary bypass. I can do all the things I want as long as I monitor myself. So far it is all that was promised. Also REI was the only store out of five that could answer the questions I had concerning Heart Monitors.
Pros: Accurate, Comfortable, Lots Of Features, Rugged, Stylish, Waterproof
Summary: I am on my 2nd FT4, thanks to REI replacing the first one. Not even six months after using the first one, it started having trouble reading my heart rate. It showed 00 on the display a lot, and when I did finally get it to take a reading, it would show a heart rate in the low 200's with me standing still, pre-exercise. I contacted REI and they happily exchanged that one for a new one. Now, 8 months later, this one is doing the exact same thing.
Summary: Iuse it with training videos, nice to have an accurate heart rate while working out and then a caloric burn at the end. I do find the instructions written in quite a small font and not easily read.
Pros: Accurate, Compact Design, Easy To Use, Gives A Quick Reading
