There's no doubt that Sigma's RC 1209 will take your run and swim workouts to the next level. Some awesome features in the RC 1209 are its ability to measure distance, pace in minutes per mile and speed, helping you to quantify your training and reach your target times in races! There's no need to wear a foot pod because the R3 heart rate chest strap collects all the data. An audible alarm sounds if you go above or below a programmable heart rate zone, and it keeps track of total calories burned in an exercise session. And, it's coded so you won't have interference with your training partner's heart rate monitor.
