The M32 features the WearLink™ Coded transmitter made from a soft, fabric material. The electrodes, which pick up the heart signals, are integrated right into the strap for added flexibility and comfort. The Coded feature eliminates interference from other heart rate monitors. The OwnCal™ feature counts the calories and fat that you burn and the new OwnZone™ feature will automatically determine each day’s target zone. The M32 is the ideal unit for the serious exerciser looking to lose weight or reach the next level of fitness.
