Oregon Scientific Heart Rate Monitor (SE331)

Don't be fooled by its sleek, feminine style! The Zone Trainer 1.0 from Oregon Scientific is especially designed for health-conscious women on the go.

Functioning as both a watch and an accurate heart rate monitor, this device features patented lens sensor technology so you can read your heart rate with just a tap of your finger. It also comes with an adjustable dual mode chest belt that transmits your heart rate information to the watch or your exercise machine. The watch's soft silicon strap is not only pretty, but breathable and gentle on sensitive skin, helping to minimize the irritation caused by sweating.

So throw away those ugly, masculine heart rate monitoring watches that are too heavy for your wrist - get the Zone Trainer 1.0 and start exercising with elegance!
