Floating jigs

[Redeyedrooster]

I have used floaters on crawler harnesses to keep the rig from snagging debris on the bottom and keeping the bait in the strike zone when using bottom bouncers. You could use a similar technique I suppose in the spring when jigging. Perhaps a drops shot style rig?
I would tend to think the leader on the rig would have to be very short to keep it in the strike zone...(bottom 2 feet) as the Walleye are holding close to the bottom for the spawn.
Most are using a fairly heavy hair jig (1/2 - 3/4 oz) or a Cicada style bait, when jigging in the spring for walleye. This keeps the line to the jig tight so you can feel the strike.
