The Shimano Butterfly Flat-Fall Jig in Size 100 is a premium slow-pitch vertical jig designed for offshore and inshore saltwater fishing, revolutionizing traditional butterfly jigging with its unique flat-fall action. This 100g (3.52 oz) model excels in mid-water column targeting, mimicking injured baitfish with a wobbling, horizontal descent that keeps it in the strike zone longer than standard butterfly jigs. Ideal for species like tuna, yellowtail, kingfish, grouper, calico bass, and rockfish, it's particularly effective in West Coast kelp beds or over reefs. The hydrodynamic flat keel ensures a fluttering fall, while the center-balanced design promotes bites on the drop.

Crafted with high-quality materials, it comes pre-rigged with two Owner Dancing Stinger hooks on 250 lb PowerPro assist cord for reliable hookups. Available in multiple colors to match local forage, this jig pairs best with 300–600g-class jigging rods (like the Daiwa Proteus EX) and high-gear-ratio reels spooled with 40–65 lb braid. As of October 2025, prices range from $18–$25 depending on retailer and color; check sites like Tackle Express or TackleDirect for stock.
