Polar - G3 GPS Sensor

The Polar RS800 training system gave runners and serious endurance athletes the most complete heart-rate-based training solution yet. Now Polar has take the system a step further by launching the G3 GPS sensor, a compact and lightweight GPS module that communicates wirelessly to the RS800 wristwatch, letting athletes take speed and distance measurements for a variety of sports, including cycling, Nordic skiing, inline skating, and kayaking. Incorporating the SiRFstarIII chipset, the G3 sensor offers excellent coverage, a fast time to first fix, and optimal power consumption. More importantly, the addition of the G3 sensor makes the RS800 the most comprehensive planning and analysis tool available for athletes who train across multiple disciplines. Water-resistant to three bars and weighing only 80 grams (including the battery), the G3 is extremely compact and built to withstand the harshest conditions or the most extreme adventure sports. The G3, which requires a single AA battery for up to 20 hours of continual use, measures 2.36 by 2.44 by 0.94 inches (W x H x D) and includes a strap and storage pouch.
