Casio ProTrek PRG300-1A2 Triple Sensor Solar Watch


  • The Casio Triple Sensor Solar Powered PRG300-1A2 keeps you one step ahead of Mother Nature by incorporating Casio's new Triple Sensor Version 3 engine. Advanced CASIO original technology has allowed for a 95% smaller direction sensor and 90% reduction in sensor power consumption compared to previous models.

    Despite their smaller size, the new sensors in this model delivers better accuracy and energy efficiency. This model can measure Altitude in 1m increments (previously 5m) and display compass readings with 60-seconds of continuous measurement (previously 20 seconds).

    In addition to the altimeter and digital compass, the watch's Barometer, incorporates a unique Barometric Pressure Tendency Alarm that alerts the wearer to sudden changes in pressure readings.

    This is a sleek and compact case with a soft urethane band for a better fit to the wrist. One-touch access to digital compass, barometric pressure/altitude, and temperature readings keep important information at your fingertips. Everything about these models is designed and engineered to make them essential pieces of outdoor solar gear.
