For locating structure, especially minute structure, night time is the Only time. I have won doing just this......... It was an area that had huge fish but nearly no structure to be found during the day There were only a couple stumps and a remnant of two old sunken cedars. In this same general area I was able to locate 7 or 8 other remnant stumps(very small) and a couple small tree branches and two concrete house blocks before daylight the next morning. These were the spots that won the tourney for me.

Thanks,
Ronnie
