Any idea why my fish finders depth keep changing?

  1. You have a school or two of fish swimming below your hole. Looking at the solid red marks from about 6 feet to bottom. So you have fish that are sitting in that common zone of a foot or two off bottom.
    Being’s your shallow, depending on the sensitivity it could be a bunch of perch, sunfish, or bigger fish, idk.

    It could be a really soft muddy bottom. There also could be something on your transducer or a bad transducer. Try moving to a different spot.

  3. If you’re on Upper Red, it means you’re drifting because the ice shelf you’re on, has broken off and now you’re stranded unless you’ve got ladders and planks.

    OTHERWISE, I’m guessing it’s a muddy bottom thing.

  4. Could be a few things. Most obvious is that your return isnt changing just the depth #. That means your ducers is probably goid and giving back a solid return.

    Maybe a super soft bottom. maybe theres some weeds, looks like about 2 feet of something above a bottom of 7ft.

    The number your finder spits out is just its best guess at which of the marks is the bottom, it doesnt really mean anything. If you set you range shallower than bottom it would pickup a fish as bottom when it swims through. Set your range over twice the depth on a hard bottom and it might read twice the depth due to the double return. Its really no better than the silly fish indicator mode you can turn on. Go off the graph not numbers.
