Staying Still on the Touchdown While Pitching for Bass
You want to end the fall to the bottom well when your jig hits bottom. Try to get it to land close to something inactive fish might be under.
Cuts under rocks, under logs, brush tangles, big limps at fall trunks, etc: all of these places are great to land near.
If it is hard bottom, look to make a "heavy thud" kind of landing. If it is soft or weedbed bottom, look to make a "light" touchdown. In any case, just let it lay there, and don't move!
Let it sit for at least 10 seconds. Don't flinch. Don't move your rod tip. Just. Stay. Still. Often, the bass can't stand this, and will snap up your jig!
