One of my better screen shots, but unfortunately I did not return to it or mark a waypoint on it at the time. Wouldn't really have done me any good, now ... since the unit I took the screenshot on is defunct & has been replaced.
Image was taken on a Lowrance Elite 5 DSI .... current unit is a Lowrance Hook 7
Other than this one screenshot, most "fish" show up as white dots on Down Image screens. Down Image is all I use, even on the Hook 7, because I'm mostly looking for submerged brush or Shad schools ... depending on how I'm fishing.
