JLT Mobile Computers has successfully united power, design and toughness into its G-Force 850 tablet PC. Weighing less than 4 pounds, this ultra-rugged device is built watertight, shockproof and dustproof in an IP65 sealed housing. Intended for use in remote, outdoor environments, the G-Force's full charge lasts approximately 5 hours and the battery can be swapped without rebooting. A bright display with resistive touchsreen makes it ideal for outdoor field use and eliminates the need for a special stylus or pen. The system is evenly balanced and has a multi-directional handgrip wrist strap, but desktop and vehicle mounts are available.
