Finally a Fish finder that every regular joe can afford. Raymarine introduced the Dragonfly 4 & 5 at the 2015 Consumer Electronics Show. Now you can get down vision technology for as little as $200 bucks. You can get a decent unit with most of the bells and whistles for $300. Now I can finally afford one.
