Finaly got out on the ice today in the Cincinnati area. Tried a few private ponds and lakes, also parts of Winton Woods. Ice was a good 4" in most places with some spots going 5-6". Rarley did I see anything below 4". I marked a few fish about 4 feet deep in 6 feet of water. I tried spikes, waxies powerbait and everything in between. Also, I was only marking fish in one hole. I drilled holes next to it and nothing. My question is how does the sonar operate on a smart cast Humming bird. Does it pick up whats directly benath it? The screen scrolls and I'm not sure if the fish and structure I'm seeing is directly benath the sonar, or around it. Please, someone give me a lesson with fish finders!
