Introducing Triple Sensor Version 3, advanced CASIO original technology that makes it possible to pack sensors that are 95% smaller than those of previous models into a totally new type of compact PRO TREK. Despite their smaller size, the new sensors in these models deliver higher reading accuracy and improved energy efficiency.These Triple Sensor models deliver altitude, barometric pressure, and direction readings that are more accurate than previous models, and a Barometric Pressure Tendency Alarm alerts the wearer to sudden changes in pressure readings.Design features include a case designed for outdoor gear performance. Large side buttons and one-press access to digital compass, barometric pressure and altitude, and temperature readings keep important information at your fingertips.Other features include Tough Solar, 100-meter water resistance, and more. Everything about these models is designed and engineered to make them essential pieces of outdoor gear.
