There are a number of sunshades for various Lowrance Hook Reveal models, but I really wasn't satisfied with them for one reason or another. Some of my dislikes were multiple pieces, flimsy looking, prevented angle adjustment, and most important to me was being able to positively attach it to the Lowrance. I took inspiration from a number of ideas folks had, most notably Lowrance Hook 5 Reveal Sun Cover by orlovkem. I liked the rounded front, didn't like the shelf, not sure what the text meant, but overall, I thought the slip down over the top idea was solid. I also needed this for the Reveal 7, not the 5. I wanted to be able to positively attach the sunshade so there are tabs that go between the angle adjust screws and the Hook 7 and can be adjusted while the sunshade is on the device. Borrowed the Lowrance logo from their website and added that to the top.
