It was not so long ago that Raymarine introduced the highly coveted Dragonfly 7. It is a definite upgrade over Dragonfly Gold released earlier. It promised big, like beautiful sonar images, and for the most part, it delivers. Learn more about this high-end fish finder in this Raymarine Dragonfly7 review.
Features
Definitely the most impressive feature of this fish finder is CHIRP (Compressed High Intensity Radar Pulse) technology. CHIRP is simply superior in transmitting broad spectrum signals underwater that result in crisp and clear images. Most other fish finders use single frequency sonar in comparison. The GPS is sonar as well, which allows for smooth navigation underwater. In addition, there is a track back feature to search through history to see marked waypoints, navigational routes, recorded underwater images and many other features. Tech wise, this fish finder is impeccable.
The advantage of CHIRP technology is its “downvision” feature. It enables this sonar to generate photograph-like, or lifelike, images of objects underwater. This tech in the past was only available in premium fish finders that cost thousands of dollars. CHIRP downvision initiates elliptical signals in layers, hence the highly detailed and clear images. The images are so superior, you can see fine detail and differences between plants, fish and terrain underwater. Combined with the multicolor display, the images are quite stunning.
This fish finder has a Raymarine exclusive CPT-60 transducer with transom mount. It’s a dual element transducer that delivers better performance than comparable fish finders. Compared to the Dragonfly 5, this updated version has a larger 7-inch screen with 800 x 640 resolution. That screen resolution is perfect for generating vibrant images captures by the CHIRP sonar. The LCD screen is backlit and has brightness at 1,500 nits, so you can see the screen in bright sunlight without an issue. Overall dimensions of this fish finder are 12 by 10 by 6 and the weight is about 5 pounds. All in all, this is a highly portable fish finder suitable for beginners and professionals alike.
This fish finder is equipped with a superb 50-channel GPS chart plotter. It functions on highly-acclaimed Navionics cartography. This GPS device can provide precise data down to 600 feet underwater. You can collect information such as bottom depth, gradient depth, water temperature, and speed of the watercraft. The chart plotter is very detailed, probably more detailed than many hobbyists require. In addition to real time data, this fish finder has U.S. coastal and inland water charts stored in the SD card provided. You can use these charts to improve your navigational route and expand the area you cover with less risk.
Ease of Use
Though the Dragonfly 7 comes packed with high-tech tools, it’s really easy to use. You don’t need a degree in maritime cartography to understand how this device works or to read the screen. Operation is quite easy. It’s just like using a tablet or a smartphone. There are physical buttons to quickly do things like adjust screen brightness, zoom in and out, scroll through screens, access the menu or change map modes. Almost no tinkering is required as most features are accessible with a single push of a button.
Also, the fish finder is easy to rotate for better viewing. The mount is flexible so you can rotate or tilt the fish finder to get the most comfortable viewing angle. There’s a quick release button to remove the device from the mount when needed. You can split the screen horizontally to view sonar and maps side by side and compare. In addition, the sonar auto focuses so there’s no button for that. While some people may consider that a downside, keep in mind that auto focus sonar eliminates the time you need to tinker with the device and enables you to get on with the fishing.
The Cons
There is only one true con that is really minor. The main drawback is the shorter than average power cable. The power cable is designed for small boats. If the boat is medium or large sized, you will need to get extension cords to acquire the desired length. Also, as mentioned above, there’s no button to adjust sonar focus as it auto focuses.
Overall Impression
All in all, this Raymarine Dragonfly7 review finds the device a superior fish finder that is worth every penny. It’s easy to use and generates incredibly detailed and photographic images of objects underwater. It’s convenient to use and handle as well. The device is waterproof and has all-weather screen display. Chart plotting is quite impressive and you can definitely improve your navigational capabilities using this in your boat.
