The Delkin ImageRouter is designed for use by the serious or professional photographer who uses multiple cards on a shoot, and will save you a significant amount of time transferring your images to a computer. Constantly having to load and unload cards from a reader means you are tied to your desk during the whole process. The ImageRouter frees you from your desk and greatly improves workflow efficiency by providing four CompactFlash card slots for simultaneous download. Users can also hook up multiple ImageRouter card readers, or other types of card readers for even more slots because the Imagewriter is also a powered USB Hub.
