Raise the bar on your physical fitness with the TomTom Cardio MultiSport Watch Plus Cycle. This multisport watch combines high accuracy, built in heart rate monitoring with QuickGPSFix Technology, keeping you on pace for your next marathon, bike race, or swim meet by measuring target heart rate, time, distance, and calories burned. Working indoors when it's dumping or freezing outside, the watch's built in accelerometer gives accurate readings on treadmills without the use of GPS. In addition, this version Plus Cycle features a built in altitude sensor and speedcadence sensor that hooks up to your bike for accurate measurement of pedal stroke and speed in real time. Bringing innovative technology into the equation, the watch's built in heart rate monitor frees you from chest strap heart rate monitors when you're running and swimming. Biking still requires the use of a chest strap, so TomTom bundled a chest strap heart rate monitor. The high accuracy, built in heart rate monitor measures changes in blood flow in your wrist by shining light through the skin and detecting changes in reflection. To ensure its accuracy, TomTom tested this device alongside electrocardiography and determined it to be extremely accurate for light exercise and high intensity use alike. The built in intensity zones allow you to step up your game, one level at a time. Five different zones help you burn fat or improve speed and fitness goals by regulating your intensity each step of the way. In addition, this watch allows you to set target zones based on pace or heart rate, record laps based on time, distance, or user defined settings. Plus, you can race against your previous best performances. Bundled in the box with the Cardio MultiSport Watch is the following: chest strap heart rate monitor for bike use, speedcadence sensor, bike mount, USB desk dock, and user manual. It connects to both PC and Mac via the included USB desk dock, and the TomTom MySports Web Tool allows you to sync...
