The G-Force 850 mobile computer features a high-quality, 8.4-inch display that is easy to read — even during daylight hours. On one battery charge, the 3.5-pound tablet PC operates for five hours during full operation or eight hours using a power-saving feature. All forms of wireless and radio-modem communications are supported. Designed for heavy-duty applications, the computer is sealed for protection from dust and brief submersion in water. The touch screen can be converted from portrait to landscape and is high-resolution for viewing detail.
