Just curious is that the new Lakemaster Premium VX v1.0 card? The one with the smart strike capability? I bought one last June with a new Helix 10 G4 DI/SI/ GPS. The card worked fine for a month or two then it wouldn't let me adjust lake level offset. It still would show the lake at normal pool depth, but couldn't offset anything depth / shallow water etc. It happened one day after I was playing with the unit and hit MOB (man overboard) button. I finally got that way point cleared and it still isn't right even did a factory reset to default settings nothing. Kind of forgot about it since it's on a pontoon and only used in the summer. MY old V2.0 Lakemaster have never given me an issue in 9 years.
