I am having trouble understanding my graph. I have some structure sunk in some lakes now but not sure how to exactly pinpoint where to drop my marker bouy. Whenever I run over it and it immediately is beginning to show on the far right side of my graph does this mean it is directly under my transducer? or since its showing up on the right side of my graph its on the right side of my boat? just having trouble knowing when and where to drop my marker.
