Raymarine Dragonfly 4 Pro Navionics+ Dual Channel Sonar/GPS

Raymarine Dragonfly 4 Pro

Raymarine Dragonfly 4 Pro Navionics+ Dual Channel Sonar/GPS is the best fishfinder gps combo with a great color display and impeccable sonar accuracy. I highly recommend this for anyone looking for an easy to use model that can serve both as a fishfinder/chartplotter and as a communication tool through which you can send sonar captures to friends, family and fellow fishing-lovers.

You can mount it anywhere you like

One of the greatest benefits of the Raymarine Dragonfly 4 Pro Navionics+ Dual Channel Sonar/GPS is that it is incredibly easy to mount on your boat. The compact ball and socket mounting system means you can install it anywhere in your field of vision that is most comfortable to you so that you can easily consult it as you drive and search for fish. You won't have to pull it out every few minutes to check on new images - they will appear as you drive, allowing you all the freedom in the world

Incredible Sonar capabilities

No one can see every little detail of the river on their own - even if you stay really still and can see all the way down to the bottom. Equipped with CHIRP technology, the Dragonfly's DownVision sonar is able to transmit multiple frequencies simultaneously. I can guarantee this will result in life-like results on your display screen. The resolution is so high, you might even be able to guess what type of fish you've just caught on the sonar. The details are so crisp and crystal clear, you will amaze your friends and family and heighten their interest in fishing.

100% clear vision, no matter the weather

If you want sharper contrasts, fantastic visibility and exceptional detail, I suggest you take a closer look at the Dragonfly Pro. Each model is equipped with optical bonding LCD technology, which means your display will always be in high definition. You will see every nook and cranny under the water and be able to distinguish rocks from fish from bait. In addition, no matter the weather, the screen will never fog up, ensuring impeccable visibility at all times.

Connect with friends and family with the mobile app!

In addition to having the Dragonfly PRO right in front of you, you can download images to your phone right from the model by way of the app. You can also stream the sonar data right into a tablet or smartphone! The app is called the Raymarine Wi-Fish (mobile app). So if you want to share your adventures and/or compare war stories with your buds, don't just get the Dragonfly PRO, get the app! Bring your adventures to a barbecue and tempt them first by showing some of the sonar images online! It's a great way to bring friends and family into the conversation who perhaps have less of a grasp on the wide world of fishing. In our visual culture, this can also help you teach others just how cool fishfinding and chartplotting is.
