Used primarily by fire departments, utility companies, police agencies, field service companies, and telecommunications workers, the rugged computer is a miracle of a machine as it is as tough as the people who work in these professions. These computers can be submerged in water, shaken by vibrations and impacts, weigh about as much as a large car battery, and still keep on operating like there is nothing different. The rugged computer is completely sealed so as to keep out dust, the humidity, and water itself. These tough machines can put up with just about any element or condition that you can put it up against and it will keep on going.
