This screen never fogs over when there are changes in weather. Raymarine Dragonfly-4 Pro is relatively easy to install as well. It comes inclusive of a connector for power and transducer signals.

Raymarine Dragonfly-4 Pro’s CHIRP Downvision provides incredible clarity of the bottom in Downscan. It also provides a superior target separation for structures, objects, brush, fish, and so much more, in both sonar models. This unit is designed for high speed tracking meaning a user will be able to attain information of what is below them even when their boat is at high speeds (20 – 40 mph). However, your images might not have the best clarity – some of the best quality images are obtained at 2 – 5 mps.

How to use Raymarine Dragonfly-4 Pro

Raymarine Dragonfly-4 Pro has split screen function which allows a fisherman to view two applications simultaneously. You can choose to view CHIRP sonar and DownScan at the same time or you can change it up and view your boat’s position and one of the sonar applications, at the same time.

Raymarine Dragonfly-4 Pro uses a conical sonar beam for the conventional CHIRP sonar at a 25 degree angle. For Downvision, Raymarine Dragonfly-4 Pro uses a fan shaped beam with a 60 degree side-to-side angle and a 1.4 degree front to back. This unit has an integrated Wi-Fi module that allows you to interconnect with your Dragonfly 4PRO to your smartphone, smart-TV, or your tablet. This way, you’ll be able to stream Downvision sonar and enjoy hours of replay. It also allows a user to freeze frame, scroll back or forth.

This model uses a 72 channel internal GPS system as well.

Development of Thoughts - Raymarine Dragonfly-4 Pro

One of the best features about Raymarine Dragonfly-4 Pro is its integrated Wi-Fi that enhances flexibility and allows you to share your data – you will be able to stream the sonar later on from a wider screen, rewind, pause, and so much more. There are a few drawbacks though. Some of them are: this unit does not use NMEA connectors and it has no routes function as well. This means that you can only save record tracks and waypoints. Its screen is also a bit small, measuring in at only 4.3 inches. This is relatively small especially when you want to use split-screen function. Overall, Raymarine Dragonfly-4 Pro is a durable, portable, affordable and functional gadget that will help you find fish and so much more.
