Raymarine Dragonfly 7 Sonar GPS with CPT-60 Transducer

The Raymarine Dragonfly-7 delivers photo-like underwater images using CHIRP Down Vision sonar on it oversized 7-inch widescreen display. Dragonfly-7's dual channel CHIRP sonar lets you explore structure and target fish like never before. Unlike conventional imaging sonars that transmit a single frequency with each pulse, Dragonfly-7's Down Vision sonar uses CHIRP technology to transmit across a wide spectrum of sonar frequencies with each pulse - the result is much higher resolution, life-like sonar images.
