I have a striker 7sv also, Does scanning both sides vs only scanning the right (or left) side have any effect on the clarity, sensitivity etc. Also I have noticed that that there is a lag in structure showing up on the screen. Example; moving along, scanning a pier structure, the transducer will be even with the first posts of the pier but will not see any indication on the screen until the boat has moved forward 5/6 ft. Does distance from object have an effect on the size? Will a 10' high brush pile located 10 ft from the transducer show up as the same size as one 40 ft from it?
