For jigging,which is just another name for Deep Sea Fishing you will need a jig.
Jig is special lure that contains lead sinker inside, and around it a rubber cover is moulded. Hook is also a part of this lure. Different sizes and weights of jigs exist, and anglers choose them according to a fish size, location and year time. Here in Playa del Carmen we use a thick one, because of the big bites.
Unlike swimbaits and similar lures that move horizontally, jigs are presented in a vertical motion, mostly to fish near the bottom.
To be able to practice this technique, you will need a suitable rod which is sensitive and the angler can feel the fish strike and the lure itself.
