    Whether in the desert, jungle, snowy mountain terrain or wilderness, every outdoor environment becomes a field of activity. RANGEMAN is built to achieve the ultimate toughness that G-SHOCK pursues, with high specifications for shock, dust/mud and water resistance, and advanced survival features ranging from GPS signal reception to Triple Sensor and solar operation of every function. Bluetooth communication has been added to enable linking with smartphones. G-SHOCK continues its relentless challenge as the leader in acquiring the toughness and functionality to operate at extreme limits. A “survival-tough” new RANGEMAN is born.
