 How come there is such a small land spot? I dont know if that explains my question. How come there is so much black in between the center line and the land? My sonar always looks like this.

Welcome to the forum the center line is you the black space is the water colume under you and you can see the bottom. The water depth almost equals the range width that is why you don't see much bottom so to get more bottom in that deep of water set your range to 150 feet or more. Gary

 So the black space is the bottom? I thought the blue space on the sides was the bottom? Im sorry for sounding dumb but I dont understand

The black space is what is under the transducer.  The blue is the bottom on each side.  To see more of the side bottom in deeper water, increase the range or view one side at a time.

It looks like you are in rather deep water.  The black space at the top of the screen is the approximate depth of the water you are in when you took the screenshot.  You are showing a total  screen width of about 150' which includes the water depth.  The blue areas on each side of the "black space" (Water Column) is the bottom (land) on each side of the water column.

If you had been in 10' of water at that time, you would have seen a dramatic difference in the colors.

(Just My Opinion)  LOL

Welcome to the forum.

You need to adjust your SI range.  A good rule of thumb would be to have it set to 3 to 4 your depth.  So in 60' of water, you would probably want to set it to around 180' per side.

Depending on what you are looking for, your range will vary with depth. Larger targets like shipwrecks will allow you to set a much larger range say up to 240'.  If you are looking for fish, a shorter range is better since they will be much harder to see.  This is where the 3 to 4 times your depth comes in.  So in 20' of water, say 60 to 80' range.

Hope that helps.
