The Rangeman is one of the newer additions to Casio's popular 'Master of G' collection of highly-durable and high tech wrist watches. These very impressive time pieces are constructed to withstand the most treacherous environments imaginable. Features such as Mud Resistance, Shock Resistance, and Water Resistance make sure nothing comes close to harming its inner mechanism. A Triple Sensor function allows it to display altitude, barometer, temperature, and compass readings at the touch of a button.
