Product Description:

Released: July 2015

Stay one step ahead of Mother Nature with the Solar Powered PRG300, 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 deliver 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.

Design features include a compact, sleek case and 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 gear.
