The Emereldas lures feature attachment points that are designed to use in conjunction with the Agorig Sinker system and the EG-Snap, this allows for changes in sink speed, depth and angle. By attaching the Agorig sinker to the keel eye the jig will glide slowly at a 30-45 degree angle, but when attached to an EG-Snap the lure will sink rapidly at a 75 degree angle. This is ideal for deep water or fast current situations.
