Shouldn’t show two depths. Could that possibly be a depth number and a temperature? The main thing I figured about about my basic fish finders is they are really more for finding the right depth, bottom hardness (if it’s a color screen) and temp. For instance the very first one ever owned would show fish symbols. I always said they just had a recording on it until I got my better units. I think the main thing you need to focus on is when you catch a fish look at the finder and see what’s the depth, temp, bottom hardness, and did the finder show something on the screen at the time of the catch. I used to catch fish when mine didn’t show anything and when I’d stop catching them it would show fish. I guess it was because I fish in front of the boat and it only shows what’s directly beneath. Then I would float forward and it would show the fish I was just catching. As far as structure don’t try and guess what it is. Just know there is are variation of something different on the bottom and that attracts fish. The best thing to do is sink a tree somewhere you know and look at it when it is first sank and then check it every time out. You see something different on it and it’s probably fish. Only thing that’s going to make you better with it is to use it regularly
