The Berley Pro fishfinder visors are designed to keep the sun and water off your console screen when your fish finder is in a open water environment. By using a fish finder visor, you can reduce your screen brightness and still see the screen clearly thus prolonging battery life. The visor also reduces cleaning, since it acts as splash protection. This visor can be installed in 5-minutes using 2 included stainless steel fasteners.

so far so good. I love that it casts a shade all the way around the unit that I can decrease the background light. Which then saves battery!!
