Casio’s launch of the G-Shock Rangeman, without question, was an incredible success. The GW9400 Master of G series is the 1st G-Shock equipped with Casio’s 3rd generation triple sensors (or to use triple sensor in general), in order to display compass bearing, atmospheric pressure/temperature, and altitude. As compared to their 1st triple sensor from 1994, the 3rd generation is not only reduced in size by 95%, but also 90% less power consuming and more accurate. Casio has also used a cylindrical button guard structure for smoother, more precise, and protected button operation and stainless steel button shaft to ensure a more durable performance with frequent use. This is now G-Shocks ultimate survival watch.
The new Rangeman also has the full on functionality and durability found throughout the G-Shock brand. Shock resistance is of course a must, but it is also mud resistant, low temperature resistant and water resistant to 200m. One of the best parts is that the Rangeman is Tough Solar having a maximum power reserve of 23 months in sleep mode from a full charge, plus Multiband 6 for atomic timekeeping.
By pushing the right middle button once you can access the 1st of your 3 different sensors. The 1st sensor is distinguished by a single audible beep and will display your current altitude. The sub dial at 10:00 will be your altitude differential graph, to check the difference between current altitude and a reference point. This gauge will measure the difference in meters. At the top of the screen, you will see the altitude tendency graph (which can be switched to relative altitude by pushing the upper left button), and is updated every time you take a reading. Below that is your current time. On the main portion of the display you will see the altitude read out. The Rangeman is capable of measuring -2,300 to 32,800 ft.
Pushing the middle right button again will bring you to your compass, which is recognized by a double audible beep. It is important to have the watch level in order to get an accurate reading. The sub dial at 10:00 will have a a digital indicator that will point North. The top of the screen will display your bearing objective, telling you what direction you are facing from the 12:00 area of the watch. Below that, your current time will be displayed again. The main portion of the screen will display the bearing angle to the objective. This compass can run for 60 seconds as opposed to the 2nd generations 20 second length and uses 1/10th the power in comparison.
By pushing the middle right button one more time, you will hear a 3 beep indication which means the watch is now in barometer mode. The 10:00 sub dial in this mode will display with a single digital line to indicate differential in barometric pressure. The line in the picture is currently pointing to “0″ meaning no change. If it were to move towards the “10″ on the red ring, it means an increase in pressure, and towards “-10″ a decrease. The top of the screen will display a graph that shows a chronological history of pressure readings. Below that is your current temperature, which is most accurately read when off of your wrist for about 20 minutes, as body temperature will affect it. The main portion of the screen displays current barometric pressure in inHg (as pictured). You can adjust all sensor measurements to display in either US or Metric measurements in timekeeping mode by holding down the upper right button for about 3 seconds, using the lower left button to find unit adjustment and use the upper, middle and lower button to change temperature, altitude, and barometer measurements respectfully.
Pushing the lower left button will take you out of your sensors and back to timekeeping mode. Timekeeping mode displays time, day, date and month as well as AM/PM. The 10:00 sub dial will act a a second hand unless the stopwatch is in progress or paused.
Pushing the lower left button once from timekeeping mode will put in World Time mode. This allows for easy changing of timezones by using the upper and lower right buttons. You will have 48 city codes to choose from to display one of 31 timezones. The top of the screen displays the city code, below is your display of home time, and your world time’s display is in the main portion of the screen.
Pushing the lower left button again will pull up your stopwatch. Your stopwatch can be started/paused by using the lower right button and reset by using the upper right. This can measure anywhere from 1/100th of a second up to 1,000 hours.
Pushing the lower left button again will bring up your countdown timer. The can be set for as low as 1 minute up to 24 hours. Pushing the lower right button will start or pause your timer, the upper right button will reset. Once the timer goes off, 10 audible beeps will sound.
The next mode is your alarm. There’s actually 5 of them one of which you can snooze. You can turn the alarms on or off by pushing the upper right button and switch to through your different alarms by pushing the lower right. Setting the alarms is done by holding down the upper left button for about 3 seconds on the alarm you of your choice and using the lower left and upper and lower right to change hours and minutes. Once the alarm sounds, 10 double beeps will sound. You can also set an hourly time signal so the watch will produce 1 double beep, on the hour, every hour.
The next mode is an indicator for sunrise and sunset times, based on the set city code and latitude/longitude. You can scroll through and see sunrise/sunset from different dates by using the upper and lower right button.
The next mode is your data recall. Basically, you can record up to 40 logs for date/time, bearing, and barometric pressure/temperature records. To record the info, you simply hold down the upper right button for 2-3 seconds in the desired mode you want to record.
As I mentioned before, this piece is radio controlled. The final mode will scroll “R/C RECEIVED” along the top of the screen. In this mode you can manually attempt to connect to the signal by holding down the lower right button until “R/C HOLD” appears at the top of the screen. This piece will automatically attempt to receive signal on its own between midnight and 5AM, so the manual receive shouldn’t be necessary. Pictured above is an example of the watches white LED light, that can be set for a duration time of 1 or 3 seconds. The light is activated by pushing the button at the 6:00 area.
The Rangeman measures out at 53.5mm wide and 18.2mm thick, which sounds gargantuan, but definitely does not wear that large. While it is still a big watch, these measurements are from the furthest points out, so it is a little deceiving. It is a wide design to help with legibility, which it definitely does, and is also very comfortable to wear as it is only 93g in weight. As always and most important, G-Shock’s impressive designs look awesome on the wrist!
The case back is forged stainless steel with a cool impression of the G-Shock Wild Cat character. This symbolizes the Rangeman’s unrestricted movement through the wilderness.
