Garmin has updated its Forerunner GPS watch family, announcing the Forerunner 310XT and Forerunner 405CX this morning.
The Garmin Forerunner 405CX succeeds the widely popular Forerunner 405 and adds some new features. Designed for the single-sport crowd, the 405CX has an improved algorithm developed by Finland’s Firstbeat Technologies that more accurately detects heart rate and calculates calorie consumption. Like its predecessor, the Forerunner 405CX can track your GPS position and calculate distance and speed. It can also be used indoors with a separate foot pod. Rather than using cumbersome buttons, the 405CX has a touch bezel that makes it easy to navigate functions while exercising. If you choose to exercise with a 405CX-provided Virtual Partner, you can even adjust its speed via the bezel. The 60-gram GPS watch, which comes with straps for small and large wrists, is waterproof.
Moving on, the Forerunner 310XT is designed for the multi-sport crowd, succeeding the Forerunner 305. Waterproof to a depth of 50 meters, the Forerunner 310XT can be combined with a new waterproof heart rate monitor, improving the transition time in the event of a triathlon for instance. In fact, different sports can be categorized on the 310XT along with the transition times between them. Additionally, the GPS watch has a 20 hour battery life and a quick-release strap that makes it easy to move it from your wrist to your bike and back. Like the Forerunner 405CX, the 310XT also tracks heart rate, calorie consumption, GPS location, speed and distance.
Both GPS watches use ANT+ technology to wirelessly transmit data between your PC and watch, or between watches. ANT+ makes it easy to share workouts with friends, upload workout information from your computer, or transfer workout statistics to a computer for analysis.
The Forerunner 405CX, Forerunner 310XT, and the new heart rate strap will all be available in the summer of 2009. Garmin hasn’t released any pricing information yet.
