I know theres alot posted on here and I have read most but I still got a question or 3. 1. does the SI picture scroll across the screen? is it like taking a photograph? is it like looking live through a video camera? hows that work? 2. how would you use it, look at certain spots or troll along looking at everything? 3. can you see "catfish" on it. Ive seen bait fish suspended and white perch suspended but can you pick up a fat hawg laying or cruising the bottom? got a picture of it? I saw deerhunters picture but hard to read with insert window and zoom. I hope to get one soon but not sure how it works.
