I have the dff3d in tz3 and I have the problem shown in the photo, I always have a mountain range on my right which does not exist normally, apart from wiring control I am afraid that the transducer is not installed correctly as it is 8 inches right from the hull but still the mountain range is always shown to the right which could not be the deadrise which is to the left. the boat is regulator 32 and the deadrise is 24 degrees, which help is welcome
