Recently bought a used boat and it came with a Lawarance Elite 7 HDI sonar unit. After playing with this unit for a while, I decided to remove all the previous owners settings using the return to default feature. Worked fine, started adding my own settings and found the down scan feature isnt to be found. It was working great before the default feature was used. I have a manual and it talks about using the down scan but no mention of how to activate it. Anyone have one of these units that can point me in the right direction. Downscan was always on one of the pages to go to, but after the return to default....no more downscan, what did I do wrong or what am I missing ???? Thanks in advance,......
