The Dragonfly 7 Pro is one of the units released by Raymarine in 2017 but it is still available at the moment. It’s a fish finder and chartplotter, but this particular model is the basic E70320 which only has the GPS plotter. However, it has a microSD card port and can be loaded with charts from Navionics, or C-MAP. It also includes the dual-channel transducer.

Sonar and transducer
The Raymarine Dragonfly 7 Pro offers two types of sonar, these being traditional CHIRP and CHIRP DownVision. The CHIRP frequency ranges are 170-230 kHz for the 2D traditional sonar, and 320-380 kHz for DownVision. Needless to say, you can work with both sonar modes in split-screen.
This Raymarine fish finder comes with the CPT-60 transducer. This is a urethane transducer featuring 33 ft. (10 m) of cable, and also has an internal temperature sensor. It comes with a transom mount; a trolling mount is not included with it. The part number for the trolling mount is A80207. Also, this fish finder unit is compatible with the newer CPT-DVS transducer.
The included CPT-60 transducer uses two beams, one for each type of sonar. For the 2D traditional CHIRP sonar, it uses a conical beam with a coverage of 25°. The maximum depth capability for this beam is 900 ft (275 m).
For CHIRP DownVision, the transducer uses a thin, oval beam, with a coverage of 60°/1.4°. The depth capability of the DownVision beam is 600 ft. (183 m).
Since it’s a fairly basic unit, it doesn’t support SideVision sonar or the newer Raymarine sonar technology RealVision 3D.
The Raymarine Dragonfly 7 Pro fish finder offers a pretty decent range of standard sonar functions. The list includes A-Scope, Target Depth ID, White Line, Bottom Line, Auto Gain, Noise Filter, Temperature Alarm, Depth Alarm, Fish Alarm, and more. The unit doesn’t have Sonar Recording and a Circular Flasher application.
As we’ve mentioned above, this is the Raymarine Dragonfly 7 Pro part number E70320. Therefore, it only has the GPS plotter feature with basic maps only for setting waypoints and recording tracks, without depth contours and other information. However, the unit does have a microSD card port and can be loaded with charts from Navionics and C-MAP. It supports LightHouse Vector and Raster Charts, Navionics Gold and HotMaps, Navionics+, and C-MAP by Jeppesen.
The unit is equipped with a 72-channel internal GPS/GLONASS receiver. It supports corrections via WAAS, EGNOS, and MSAS. It also has a GPS speed function so it can calculate and show the speed of your boat.
The unit has a waypoint creation and track recording functions. You can save up to 3,000 waypoints in its memory and group your waypoints by categories. There quite a few icons available in the unit’s database so that you can personalize each waypoint better. As for the tracks, you can save up to 15 into the unit’s memory, and each track can have up to 10,000 points). The unit does not have route creation and trip planning features. It also does not support AIS, Radar or auto-pilot modules.
Control unit features
The Raymarine Dragonfly 7 Pro features a 7-inch WVGA color display, with a pixel resolution of 800H x 480V and an aspect ration of 15:9. It has LED backlight for superior readability in direct sunlight. It is also IPX6 and IPX7 waterproof which essentially means that it can withstand high-pressure sprays of water, rain, incidental water exposure, and even complete immersions in freshwater.
The unit doesn’t have touchscreen technology. It is equipped with a large directional and selection trackpad, +/- zoom buttons, a back command button, and the power button. Its interface is very easy to use; it has pre-determined split-modes for chart and sonar, split-sonar view. It only allows the usage of two applications in split-view, but you can either have them side by side or one on top of the other.
The unit doesn’t support NMEA networks and does not have Ethernet. However, it has built-in wireless connectivity (WiFi). Therefore, you can sync it with your smartphone via the Wi-Fish app, in order to view the sonar application on your phone. This allows you to rewind sonar or take sonar snapshots.
As we’ve mentioned above, the Dragonfly 7 Pro is equipped with a microSD card slot placed on the back of the unit. Therefore, the unit can be loaded with C-MAP, LightHouse, or Navionics charts.
Last but not least, the unit comes with the tilt-and-swivel ball mount and has the unified connector for both the transducer and power cable. A unit cover is not included, though.
