Check out the Dragonfly here at http://www.fishfindersource.com/shop-fish-finders-by-brand/raymarine-fish-finders/dragonfly-fish-finder-gps-5-7-display/
The Raymarine Dragonfly is an awesome new fish finder that brings technology that used to cost thousands of dollars to fishermen like us for a fraction of the cost. Sporting a 5.7 inch display that colors pop out of, and a 50 channel GPS, the Dragonfly is a neat little package that packs a big punch.
The biggest punch by far is the CHIRP SONAR. CHIRP SONAR sends out a fan of sonar waves instead of just one beam – and this lets you see a much, much clearer picture than even the best DownScan and Down Imaging SONAR. CHIRP is so good that you can actually make out the shape of fish underwater.
The Dragonfly is very easy to set up and use. It is operated with only 3 buttons(that’s all you need), and the fishfinder does all the sonar adjustments by itself. You don’t need to worry about anything. Just hook it up and start fishing.
You can use the Dragonfly fish finder for both freshwater and saltwater fishing, and there is a temperature sensor built in. The GPS will give you readings for speed.
The only issue I see with the Dragonfly is that professional anglers may not like the fact that you can’t tweak the sonar to your own preferences. Many pro fishermen like to tweak the settings until they find a “sweet spot” – this you can’t do with the Dragonfly.
Otherwise, the Raymarine Dragonfly is a beautiful unit that will surely up your fishing game.
