Raymarine Dragonfly-7 Pro GPS fishfinder with Navionics ROW Silver Chart

The Dragonfly 7 PRO Combo - Navionics Silver chart for rest of world (not US) - offers dual CHIRP sonar channels (traditional sonar and Downvision) and a chartplotter. Unlike conventional fishfinders that transmit at a single frequency with each pulse, Dragonflys dual channel sonar uses CHIRP technology to transmit across a wide spectrum of sonar frequencies simultaneously – the result is much higher-resolution, life-like sonar images. Dragonfly PRO models feature built in Wi-Fi. Anglers can stream Dragonfly sonar data right to their smartphone or tablet with the Raymarine Wi-Fish mobile app. The Wi-Fish mobile app puts Dragonfly sonar vision right in the palm of your hand, plus you can rewind and capture sonar images to share online with friends. An all weather optically bonded display delivers brighter colours, sharper contrast, and will never fog up
