What is it?
A rig with two hooks above and one hook below the lead. Clipped baits are positioned close together when casting.
Where would I use it?
Any venue where you need distance and having one hook below the lead is usually good if the tide is strong.
How should I use it?
Three hooks allows you to use three baits, but keep them small. Slide your bait stops down behind each bait (to stop it sliding up the line when you cast), clip down all the hooks starting with the bottom one first, and cast.
