The dual-layer LCD allows compass graphics to be shown on the top layer, while the bottom layer offers a large display of the time and various measurements. We’ve also made the LCD slimmer to minimize bulk, even with the dual-layer construction.
The case, case back, and soft urethane band are all made with the Earth-friendly green material known as bio-mass plastics. Using renewable organic resources such as castor oil plants and corn helps reduce the ecological footprint. Eco-consciousness rendered in physical form, a fitting material for a real outdoor tool.
*Bio-mass plastics are not used in the metal band of the PRG340T.
Measure direction, air pressure and temperature, and altitude, each one available directly from a single button. The oversized buttons feature a nonslip finish for effortless use even when wearing gloves. In addition, improved sensor placement makes the side of the case even slimmer. The buttons are easier to press now, too.
This proprietary CASIO solar-powered battery-recharging system assures stable operation of various power-hungry functions, including dial lighting, alarms, stopwatches and measurement functions.
Measuring altitudes based on changes in atmospheric pressure
The altimeter determines the altitude at your current location based on accumulated atmospheric pressure changes measured by the pressure sensor. Setting the altimeter at a location where you know the precise altitude before starting your ascent enables it to take even more precise altitude measurements.
Sea level measurement
Setting the altimeter at a location where you know the precise altitude enables you to determine the elevation of your current position with respect to sea level. If you come across a marker indicating 400 meters above sea level while hiking or climbing, for example, simply set the altimeter at 400 meters. This enables you to obtain more accurate readings with respect to sea level when you take subsequent measurements after moving on.
The altitude memory stores data on the month, date, time and results of altitude readings taken automatically at regular intervals and displays the highest and lowest altitudes measured as well as the cumulative ascent/descent altitude and relative altitude. This data provides an easily understandable summation of your ascents and descents during a climb.
- Cumulative ascent altitude : total of ascent altitudes (A + C)
- Cumulative descent altitude : total of descent altitudes (B + D)
- Highest altitude : altitude measured at the highest point E among all readings during memory measurement
- Lowest altitude : altitude measured at the lowest point F among all readings during memory measurement
- Highest/lowest previous record altitudes
- Sum of cumulative ascent/descent altitudes : computed repeatedly at time of memory measurements between 0 and 99,995 meters
Altitude differential display
Checking against contour lines on a map enables you to confirm your cumulative ascents/descents. Determining the height of your hourly ascents by resetting the altitude differential display once an hour can be helpful in establishing a reasonable climbing plan, for example.
*These measurement functions are not intended for use as professional instruments. Please use the measured data for reference purposes only.
Predicting your destination temperature based on the temperature at your current location
The temperature generally decreases by approximately 6.5°C with every increase in altitude of 1,000 meters, or 3.6°F with every increase of 1,000 feet. If the temperature at 1,000 meters is 10°C, therefore, the temperature at 3,000 meters will probably be about -3°C.
