I have used this graph a few times now and am loving having it. I have learned that it scans mostly to the left side of my boat, from center to left. It will scan to the right but not as good! I have learned that the faster I travel the cleaner the picture. I have learned that 455hz works better shallow. And 800hz work better in 10 feet or deeper. I have also learned what a bait ball looks like.
