I had ordered Ben Parker's Bass Under Glass dvd...it was ok, expecting more talk about setting up the Humminbird unit than watching him catch fish. But there is something I'm looking for that I saw on Ben's boat & don't really know what it's called. On the console, his Humminbird had a metal shield that partially covered the sides & the top of his unit. It looks like it would be easier on sunny days to read your screen. Plus it might help when the rain's hitting the face of your Humminbird making it difficult to read your map as your moving on the water. I have a 997 on my console & will be putting a 898 up front on the trolling motor. If anyone could pass along what this is called & where I can buy one for each Humminbird...I'd appreciate it.
