TRIPLE SENSOR

PRG240-5

Constantly evolving and improving the PATHFINDER / PRO TREK lineup, Casio introduces the PRG240-5, a welcome upgrade to the legendary PAG40. Beige/khaki resin band watch with neutral digital face. Tough Solar Power Triple Sensor (Altimeter/Barometer, Thermometer, Digital Compass) Sunrise & Sunset Data World Time (48 cities)

WITH FULLY AUTOMATIC DISPLAY ILLUMINATION AND DIGITAL COMPASS

The range of high-end functions means that this versatile outdoor watch always delivers: Boasting a digital compass, thermometer/barometer, altimeter up to 10,000 metres and even a sunrise and sunset display, the PRO TREK impresses not just passionate mountain climbers, but everyone who enjoys being in the great outdoors. All the information is easy to read thanks to the multi-coloured display.

SOLAR-POWERED

This proprietary CASIO solar-powered battery-recharging system assures stable operation of various power-hungry functions, including dial lighting, alarms, stopwatches and measurement functions.

POWERED BY LIGHT (TOUGH SOLAR)

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.

Altitude memory

  • Cumulative ascent altitudetotal of ascent altitudes (A + C)
  • Cumulative descent altitudetotal of descent altitudes (B + D)
  • Highest altitudealtitude measured at the highest point E among all readings during memory measurement
  • Lowest altitudealtitude measured at the lowest point F among all readings during memory measurement
  • Highest/lowest previous record altitudes
  • Sum of cumulative ascent/descent altitudescomputed 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.

HELPING EFFICIENT COLD PROTECTION THERMOMETER

Using Sunset, Sunrise time data to plan climbs

Knowing the time remaining before sunset helps you to schedule climbs to assure a safe descent, for example, or to determine the appropriate time to wake up or pitch a tent.

 

Fishing during sunrise and sunset hours when the fish are biting

Checking the sunrise and sunset times in advance gives you a good idea of when you can expect the best fishing, so you can make your fishing plans accordingly.
