The ECOGEAR Power SQUID is an innovative concept plastic worm invented by studying natural squid activity. There are many ways to rig them such as Jig head rig and Split shot rig. When a target is less active, or feeding bait for the game fish is smaller, S size (BABY SQUID) is recommended. L size has very nice balance rigged the with ECOGEAR 3D jig head, Vertical head 70gm and ECOGEAR RETRIEVE HEAD from surface to bottom range. LL size is strongly recommended for offshore deepwater jigging with heavy jig heads (slow pitching / vertical fishing). ECOGEAR SQUID lures has a good vibration even rigged with a heavy jig head in the midst of high speed action, falling and bottom bumping. It's a must for your big fish in the deeper ocean such as Kingfish, Amberjack, and big Reef Fish.
