Tungsten-made high-density compact casting jig, capable of handling super selective super tough conditions for baitfish. This jig, made from a high-density material, meets the demand for a smaller silhouette with a heavier weight. In situations where targets are selecting extremely small bait for consumption, this jig exhibits explosive power. While traditional jigs may be too large for fish to bite, smaller jigs may not reach the desired depth. With approximately 1.7 times the density of lead, this tungsten-made jig maintains a small size while providing ample weight, enabling stress-free long casts. Featuring an asymmetrical design to maintain the shape of a realistic baitfish, this jig allows for effective swimming action during retrieval and a near-horizontal posture during the fall, creating a realistic presentation of weakened baitfish.
