We are experiencing low, sporadic satellite pick up. Used to be 10 - 11, now can be as low as 4. At 4 -5 the boat won't maintain speed/engagement. I talked to ZO and they told me it had to do with the reprogramming of the satellite software and the old garmin pucks are subject to poor reception. That is the story anyway. The others that have converted, on our lake, all get 16 - 22 satellites and have no issues.....so...we dropped the $$
