I've loved my Lowerance HDS gen 2 and it's structure scan features but I have notice a problem while marking off shore structure. I will mark fish, a brush pile, etc on my screen as I see it on side imaging or downscan and fish that exact waypoint. I've noticed after marking the waypoint especially on side imaging that when I drive over the spot that I marked previously the brush or structure is not as I saw it before. I am starting to question the accuracy of the waypoints when they are used in the structure scan feature. Does anyone know how I could fix this or having the same problem?
