The Juno ST handhold GIS PDA is a first affordable compact and light weight GIS PDA in the market. To achieve this new product line, it is important to set the right visual language between a professional tool and hi-tech gadget. The dark middle frame with the yellow cover makes the whole device look slim and sophisticated. With this hi-tech gadget platform, to maximize the ergonomical limitation within the compact PDA architecture, we provide a careful considered button design and layout. As it is operated within hostile environments such as a forest, wild field or construction site, reliability and durability are essential.
