LAKE FORK- Back in the day, the drill for a crappie fishing trip went something like this: Pull up to a tree with limbs above the water, secure the boat, drop minnows down through the limbs and either catch crappie or spend 30 minutes trying and then move on to the next likely spot. Those days are long gone for Lake Fork guide Seth Vanover and other anglers savvy in the use of their “Livescope”, the latest innovation for seeing what’s below the surface of the water.
