My structure scan stopped working last week on my HDS10. The unit would power up and the 2d and chart worked but the structure page showed no source. Called Lowrance they asked about the structure scan module and if the lights were working. The module in my boat is installed where I cannot see it. So started in on my search found the module no lights were on. Tried to figure out how Cabela's installed the sucker when I bought it, they must have been magicians as I could not get to it. So hauled it up to Cabela's Wed they looked at it and said the module was not working and they would have to seen it back to lowrance

Fells like I am fishing with one eye now did not realize how much I depended on the structure scan. Hope I get back soon;
