Bottom bouncing is a technique used to catch the big fish in lakes.
Bottom bouncing basics:
use enough lead to keep line angle at 45 degree angle
set lure troll speed while lure is next to boat
drop lure until lure hits bottom
reel up so lead is just off bottom
have lead on dropper so if hung up you don't lose lure
use a floating lure so it stays off bottom
lure size should be the size of a baitfish
drop lure when bottom contour changes
The bite should be a hard take down .....set the hook!!
