Query: dependable heart rate monitor

I bought this monitor based on the price and the excellent reviews in Consumer Reports. I use it to keep my heart rate within a certain range when I do cardio at the gym. This watch is easy to use and comfortable. It appears to be accurate and has features like a chime to tell you if your heart rate is outside the maximum and minimum rates you program.The strap is comfortable and fairly easy to adjust. You can wear it above your belt while weight lifting and then slide it up to below your pecs when you need it.Overall, good and reliable.
