CASIO PROTREK Solar PRG-270-1JF Black

The triple sensor for measuring direction, air pressure, temperature and altitude, the highly visible display for transmitting measurement information, and the pursuit of usability as a full-fledged outdoor gear that quickly senses nature in any situation, PROTREK continues to evolve. From serious mountaineering and trekking to kayaking and more. It supports everyone who takes on various activities, even water sports in the world.

A new model with the newly developed "Triple Sensor Ver. 3" has been released from the Pro-Trek, which is equipped with the solar charging system "Tough Solar". Compared to the previous triple-sensor model (PRG-110), the PRG-110 reduces the interval between measurements from 5 seconds to 1 second (for the first three minutes only), and the unit of measurement has been improved from 5 meters to 1 meter. For directional measurement, the continuous measurement time has been extended from 20 seconds to 60 seconds due to the energy-saving sensor. The combination of the basic performance of this advanced measurement function and tough solar / 10 ATM water resistance made it possible to realize the specification that can endure the use in the harsh outdoor scene that changes every moment. In addition, a large direct button that can measure each function with one push of a button even when wearing gloves is installed, and practicality has been improved. Furthermore, based on the analysis of past atmospheric pressure trends, an alarm is provided to notify the user of any notable changes in atmospheric pressure, such as a sharp drop or a sudden rise in pressure. It is now possible to quickly detect barometric pressure changes that are difficult to notice. This is the birth of the Protrek, which pursued the measurement function and practicality.

The altimeter is a relative altimeter that converts changes in atmospheric pressure into altitude. If the atmospheric pressure changes according to the weather conditions, the altitude of the measured value will also change.
