Raymarine Dragonfly 7 inch Fishfinder bought new and used one season before I went to networked units on my boat which is the only thing this one won't do. Like new, comes with head unit, transducer and all wiring, quick release swivel mount, sun cover, original box, and all installation and use manuals. Has dual channel Chirp Sonar, Downvision, and GPS with Navionics maps. Might be the clearest screen of any brand I have used and definitely the most user friendly-very easy to learn the interface. Multiple split screen options that are easy to toggle between. Would be an excellent standalone unit on any boat or kayak.
