those look pretty good, you could try adjusting the angle of the ducer a bit, as any change in the weight distribution in the boat will change the clarity of the picture on the HU. Can try adjusting the sensitivity, but as usual, every day the water will be different, cloudy, more debris, etc., and adjust again. I usually left mine on auto since I ended up spending more time playing with the settings than fishing, and got frustrated at the FF and the fact I did not fish that much. LOL
