Just had a 12 Pro and the 3n1 HD transducer installed. Several times throughout the day the sidescan and downscan (I split them on the same screen) would stop scrolling or move very slowly. It was almost like the unit was having trouble reding or processing the image. After a bit it would go back to scrolling properly. Sometimes I could get it to continue by putting the unit in "standby" then waking it up. Anybody else seeing this?
