Sorry if this has been answered already. I've got a 93sv with livescope. The ghost tree has started showing up real bad an the only way to get rid of it is run Noise Rejection on high all day any lake I go to no matter what. First month I had the unit I ran noise rejection off an on low. Now if I turn NR off or on low the screen is blown out an the ghost tree is unreal no matter how much I adjust the gain. Im using a separate battery thick gauge wire. Honestly thought the ghost tree talk was far fetched....boy was I wrong. Anyone else had a similar experience?
