Basically, you can turn it on and start looking for fish as soon as you get it. The Dragonfly 7 looks good and it delivers. The Dragonfly Pro 7 helps me find even small pockets of fish so I can target and catch them. Customer reviews are very positive on this unit.
Instead, Raymarine Dragonfly PRO 4, 5, 7 and the Wi-Fish enable SonarChart Live to display in real time on the Navionics Boating app on iPhone, iPad and Android devices. SonarChart™ Live is also an excellent way to monitor the improvements your survey will bring to the SonarChart™ because contours are instantly seen while collecting sonar logs. The Dragonfly is fantastic on the water. I couldn’t read the LOW units in direct sunlight, and polarized glasses made it worse. I’m able to read the plotter, sonar, and downscan in direct sunlight with ease.
Your RaymarineAll Raymarine displays are compatible with the full range of Navionics chart cards: Navionics+, Navionics Updates, Platinum+ and HotMaps Platinum. The wifi option is a gamechanger, expecially if you take kids fishing as they can look at the sonar with their own phones and take pictures and video of the screen without looking at the main unit. Also, it takes a few seconds to both power up and power down. Purchase any Navionics+ Regions card (MSRP $149) or a Navionics+ US & Canada or Caribbean & S. America card (MSRP $199) along with a Raymarine Dragonfly 4PRO, 5M, 5PRO or 7PRO model. You can get a great deal on Raymarine Dragonfly 7 PRO here.
