I just got a Humbird 581 DI unit. I have been playing with it in simulator mode. I don't know if there is something wrong with it as it seems to be out of focus. The display seems washed out. Turing the contrast all the way up helps, but I am afraid that I won't be able to see it at all in sunlight. Has anyone else had this problem? I am going to mess with it some more, but if I can't do any better, will send it back to Cabela's
