I’m looking at the Raymarine Dragonfly4 to add to my 1994 200OVOB. Anyone have any experience with this unit? I currently have a navonicsPlus subscription on my iPhone and I use a mount to the windshield. I don’t trust my depth sounder as it is a 24 year old lowrance in dash. I like the Navonics capable dragonfly as it will give me the Navonics chart plotter map and depth sounder. It would also free up the dash hole the depth sounder uses to install a round dash mount radio. I saw the dragonfly4 has a flush mount adapter but I don’t really have a good spot to install it.
