I put an impulse 2801 fish finder in my boat, it was an old one given to me by my father in law., I turned it on and the display is extremely hard to see. I can find no way to adjust the contrast like on a model 2400 that I had. However when I go to turn it off for just a moment the scene is perfect.,help!
