Rango I believe those were crappie, But we did not catch any fish out of it. That part was my fault. LOL

Frank that log is straight under the boat. The line in the middle is where the boat has traveled. And from there to the left and right blue color is water. Then that log showing on both sides is what you get when going straight over a object.
So if you look at the standard image on the left. That is the standard unit like everyones . But then the right is the same view. The side imaging unit shoots straight down and out So your still looking to the bottom, And then out the side That picture I have the unit set on 56ft out each side.

And Yes when you move the cursor over to mark say a log. at the top of the picture it tells you how many feet to the side it is from the boat. And also how far behind the boat it is.
The marker on this shot is 75ft out from the right side of the boat ( Only shooting out from one side in this one) and when I marked it. The boat was 257 ft past the spot.
This shot is of a hole in the Tn River, AS you can see logs everywhere. And drops and humps. It near the bank and also on a big flat.(Boat is within 20ft of the bank. been running by it for years and did not know its there. Its on an inside bend.
