The Raymarine Dragonfly fish finder has included the CHIRP sonar system in its design. This means it sends many signals at a multiple frequencies and then it assembles all the returns and shows you the best realistic pictures of the fishes. This technology works with the Down Vision sonar. So you will be able to see the underwater area like never before. The Raymarine Dragonfly Fishfinder is an amazingly user friendly device with only 3 buttons on the device. Using only 3 buttons one can handle this device really comfortably.

     However, the installation design and the instructions given are not up to the mark and there are some more drawbacks. Therefore, we think that this is an average product that you can look for.
