Problems with a Lowrance unit
I have a Lowrance hook seven that is at least a couple of years old. The pictures on the conventional screen look pretty good. However, the down image pictures or images are really bad. Recently, I was sitting on a large brush pile and the down image page did not even show the structure. In addition, when you move beyond fifteen or twenty feet deep the DI bottom image almost disappears. I have tried zooming in and other manual adjustments, and there is no improvement in the DI images. Someone suggested it could be transducer problems affecting the down image only. I don't think it was an issue with the installation because it worked well for at least a couple of years. The employees at Cabellas suggested the unit needed a software update, however they could not do the upgrade. Tried calling Lowrance's call center and they are really not much help.
