Solar charging system of Tough Solar loading from the PRO TREK (Purotorekku), New model equipped with a newly developed Triple Sensor Ver.3 ※ appeared. - This model, as compared to conventional triple sensor model (PRG-110), altitude measurement is reduced to one second measurement interval from 5 seconds (only the first 3 minutes), the measurement unit has improved from 5m to 1m . Direction measurement is extended continuous measurement time 60 seconds 20 seconds by power saving of the sensor. - By combining the basic performance such as this advanced measurement functions and Tough Solar / 10 water pressure, achieving a spec that can bear to use in harsh outdoor scenes that change is ever-situation. - In addition, each function with one push even when gloves worn equipped with a large direct button that can be measured, also to improve practicality. - In addition, based on the past of the pressure trend analysis, notify an alarm if there is a change should be noted, such as steep descent and sharp rise in pressure, equipped with a pressure trend information alarm function. It is now possible to quickly grasp the changes in the noticed difficult to atmospheric pressure. - Measurement function, is the birth of the New Protrek in pursuit of practicality. - Tough Solar - And direction, altitude pressure, can measure the temperature of the triple sensor- atmospheric pressure trend display function· Pressure trend Information alarm- sunrise and sunset time display- low temperature specifications (-10 °C)Resin band (Band Color: Black)※ The Triple Sensor Ver.3And newly developed compact magnetic sensor that achieves 95% of downsizing, a pressure sensor with enhanced more measurement precision mounting. - By combining this new sensor and Casio own sensor IC with improved processing power, it was dramatically improve the function of the Triple Sensor.
