TRIPLE SENSOR 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. • Tough Solar ensures stable operation even when using power-hungry functions. • Triple Sensor: Compass, Barometer/Thermometer, Altimeter • Low temperature resistant (-10ºC/14ºF)

TECHNOLOGY FEATURES
SOLAR-POWERED
(TOUGH SOLAR)
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.
Altitude memory
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.

Forecasting the weather based on the atmospheric pressure tendency
A graphic display of atmospheric pressure readings taken at regular intervals reveals pressure trends at a glance. When the pressure is rising, the weather is likely to improve; when it's falling, there's usually worse weather ahead. This feature can remind you to take your swimming suit along, or alert you to approaching trouble.

Atmospheric pressure tendency graph / Atmospheric pressure tendency indicator
The barometer measures the atmospheric pressure every two hours automatically and displays the recent atmospheric pressure tendency and the current pressure graphically.

Aligning a map with the surrounding terrain
If you determine magnetic north with the direction measurement function and place a map beside your watch, you can align the map with the surrounding geography.
Magnetic declination correction
You can change the direction measurement standard from “magnetic north” to “true north” by inputting the magnetic declination data indicated on a topographical map to correct the direction.

Bearing Memory [selected models only]
The Bearing Memory memorizes directions detected by the direction measurement function and displays them continuously in graphic format. You can travel straight toward your destination by following a course determined with the memorized direction displayed steadily in the 12 o’clock position on your watch face. This capability also comes in handy when visibility is low due to such factors as trees or fog.

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.

Magnetic declination correction
You can change the direction measurement standard from “magnetic north” to “true north” by inputting the magnetic declination data indicated on a topographical map to correct the direction.

For quick, easy data confirmation, even in the dark or with both hands occupied
You need both hands for many outdoor activities, and you don't always have one free to illuminate your watch face in low-light conditions. The Auto Light Switch solves this problem by illuminating the light whenever you turn your wrist to bring the watch into the viewing position.
