Got my Humminbird 570DI installed and went night fishing last night. Depth readings were fine as shallow as 2 feet so no worries there as some others have had. I was fishing Barkley lake (sister lake to KY lake)trying to fish some ledges and flats near the ledges. Started with factory defaults and started tinkering. Using split screen I could see bottom contour pretty good, but the "water" was nothing but clutter (pixels). Turned "clutter" sensitivity up and down and everything else up and down. The only way to clean things up was setting sensitivity to 1 on a scale of 1 to 10.

The water was very warm 88 degrees if that matters. Never really saw a fish arch in 2D mode even though I caught a nice bass right under the boat and wondered if I dialed my settings to far back.

Just hoping some people here could give me some advise on settings or anything else I did wrong. I've never really set a fishfinder up before.

is it in clear mode or max. its a great unit you can really lean some stuff.

need to set to clear mode and see if this help.

Thanks for the replies

I tried both clear and max. Clear was better but I think I have a long way to go on getting it right. I mean I was fishing "shallow" 30 feet or less but there was so much junk on the screen that a 10lbs bass could have swam under the boat and I would never have known it.

Just hoping someone can steer me in the right direction.

The "right direction" is to take the Sensitivity settings off of Automatic and set them yourself. Then you can choose how much "junk" is displayed. Set each frequency to your liking.

Look at your unit's specifications and choose the widest coverage frequency for 2D sonar and DI.
