The Casio G-Shock Rangeman GW9400-1B is the Master of G model built for the backcountry: a triple sensor for altitude, compass bearing and barometric pressure and temperature, a metal cylinder guard around the sensor button, three alert volumes, and an inverted LCD that blacks out the whole face with orange accents. This review covers the sensors, the button design, and who actually needs a Rangeman.

The triple sensor
An altimeter for elevation, a digital compass for bearing, and a barometer for pressure trend, which is the weather forecast you get without a signal. The sensor button is guarded by a metal cylinder so it presses cleanly with gloves and does not get bumped. Press it once and it shows the last sensor mode you used.
The blackout display
An inverted LCD, light digits on a black field, with orange accents. It is harder to read in low light than a standard LCD and it looks the part. The backlight solves it at night.
Toughness
A Rangeman is a G-Shock with the sensors; the shock resistance and water rating are the reason it is on more expeditions than any other sensor watch.
Who needs it
Hikers, hunters, backcountry skiers, anyone who wants a barometer trend on the wrist. For an everyday G-Shock, the GA110. For tritium glow instead of sensors, a Luminox Atacama.
