Was in the fishing "storage area" in my basement today. I came across a Helix 5 box. I no longer have the boat that was installed on. When I picked up the box it felt heavy enough to have something in it. It was a Lowrance X-4 Pro. I don't remember ever having this but it looks to be a never used piece of electronics. I have never used one of these. Is it worth installing to find brush and shad or not?
