Raymarine Dragonfly 4 Pro Review – In Details


In our Dragonfly 4 pro review, the first feature to note is that this fish finder has a diagonal 4.3″ backlit LED. As such, you can read it in the bright light as well as during the night.

The display provides high-definition images with a 480 x 272 WQVGA resolution in an aspect ratio of 16:9. Also, the fish finder has an optical bonding feature that helps produce images with brighter colors as well as sharper contrasts.

Another plus of this characteristic is that it reduces the risk of internal fogging making it an all-weather fish finder. What’s more is that with this display, you can see your catch at various angles, meaning that chances of missing are meager.

GPS Functionality

Dragonfly 4 pro includes 50-channel GPS Chartplotter and C-map that allow fast-tracking of rivers, lakes, and other coastal locations. This GPS can allow you to plot up to 3000-waypoints as well as 150 routes.

As such, you can be sure to have an easy time once you want to go back to these points in the future. The device also includes a microSD card that will enable you to save all these with a lot of ease.

What’s more is that this device will let you have an easy time should you need to transfer the routes to another device via the SD card.

Even better, with the included SD card, you get the chance to download software upgrades from the Raymarine dragonfly website with much ease.

The transducer is attached to the control unit via a 25ft cable.

Dual-channel sonar

Another point that is worth noting in our Raymarine Dragonfly 4 review is that this fish finder uses a wide-spectrum chirp technology. This technology enhances a higher transmission of sonar signals into the water.

With the chirp DownVision sonar technology, this fish finder will let you view photo-like images of what lies under the water so that you can spot the fish.

On the other hand, the second chirp conventional channel will enable you to target fish with a lot of ease so that you do not miss your catch.

With this fish finder, you can sense the exact depth of the objects beneath the water based on the data transmitted to your LED. What’s more, is the additional sensor that will let you know the temperatures of the water.


The Raymarine 4 pro fish finder measures 13.8 x 13.8 x 13.8 inches while it weighs 2.3 pounds. As such, it is small enough to hold in your hand.

You can also use it in any sized motorized boats or kayaks. Another plus is the plug and plays feature with the quick detachment. This makes the fish finder easy to remove and stow away.

Integrated Wi-Fi module

Another smart feature in our dragonfly 4 pro fish finder review is that this fish finder allows you to use technology even while on the water. With this device, you can utilize the Raymarine Wi-fish app and interconnect your fish finder with your smartphone, or tablet. This device is compatible with IOS and other Android devices.

By utilizing this feature, you can save your day’s catch and share it with friends on your social media networks. What’s more is that with this device, you connect with your smartphone so that multiple anglers on board can view what’s happening from their smartphones without having to strain to watch the screen display.
