Thread: Anybody know why?

I have a garmin echomap plus 73sv unit, and I'm slowly learning how to use it, but can't figure out why sometimes the image will be crystal clear, and without changing anything except for moving the boat it will get so cloudy that you can't hardly tell anything about it. Sometimes it will be cloudy most all of the day, and then for whatever reason it will clear up and you can see every little detail, then all of a sudden it goes back to being cloudy. Does anybody know why it might be doing this? I have noticed that at night time it's always clearer than in the daytime. You can see in some of these screenshots that half the screen will be clear, then it starts getting cloudy and the only thing changed was the boat was moving over different water

Or since the voltage is varying that much you may have a bad connection(s)
