Shimano Butterfly Flat-Fall Jigs Size 100g

The Shimano Butterfly Flat-Fall Jig 100g sits in the sweet spot of the Flat-Fall lineup — heavy enough to reach fish holding at depth, light enough to fall slowly and stay in the strike zone. At 3.52 oz, it's a versatile mid-range weight that covers yellowtail, tuna, calico bass, and mixed-species jigging from nearshore kelp beds to offshore structure. Comes fully rigged with two Owner dancing stinger hooks on a PowerPro 250 lb assist cord.

The Flat-Fall Advantage

Most jigs fall nose-down and blow through the strike zone in seconds. The Butterfly Flat-Fall is center-balanced, so it falls horizontally in a wide, erratic wobble that mimics a dying baitfish. That horizontal fall keeps the jig in front of fish longer on every drop — and that extra hang time is often the difference between a bite and a miss on fish that won't commit to a faster presentation.

The Gap Between Too Light and Too Heavy

The 80g falls beautifully in shallow water but can struggle to reach fish in deeper structure. The 200g gets down fast but can blow through the zone in lighter current. The 100g fills that gap — it falls slowly enough to trigger strikes from suspended fish while still reaching mid-depth structure efficiently. It's the most versatile weight in the lineup for mixed-species inshore and nearshore jigging.

Rigged and Ready

The 100g Butterfly Flat-Fall comes fully rigged with two Owner dancing stinger hooks on a PowerPro 250 lb assist cord — open the package and start fishing. The stinger setup maximizes hook-up rates on fish that strike short or swipe at the jig without fully committing.

The Right Pick If...

• You're targeting yellowtail, tuna, or calico bass in 50–200 ft of water
• Fish are marking mid-column and not responding to heavier or faster jigs
• You want a versatile weight that works from kelp beds to offshore structure
• You want a rigged, ready-to-fish jig with proven Owner hooks
• You need a jig that falls slowly enough to trigger strikes from suspended fish

Best Fishing Techniques

• Free-spool drop — drop to the bottom, crank up 30 feet, then free-spool and let the jig fall on a slack line; the horizontal wobble does the work
• Cast and fall — cast the jig, free-spool as it sinks, wait for the bite, then jerk and repeat; effective on surface-feeding yellowtail and bonito
• Mid-water column jigging — work the jig through the column with short, rhythmic lifts to keep it in front of suspended fish
• Slow pitch jigging — deliberate, rhythmic lifts and drops over structure for calico bass and rockfish

Best Conditions

• Nearshore and offshore saltwater — kelp beds, rocky reefs, and mid-depth structure
• 50–200 ft of water in light to moderate current
• When fish are marking mid-column and not responding to faster or heavier presentations
• Mixed-species situations where yellowtail, tuna, calico bass, and rockfish are all in the spread

Best For

• Species: Yellowtail, Bluefin Tuna, Calico Bass, Bonito, Rockfish, Lingcod
• Techniques: Free-spool drop, cast and fall, mid-water column jigging, slow pitch

Tackle Express Tips

• Match color to local forage: Black Anchovy and Blue Sardine are natural matches for the sardine and anchovy forage common in Southern California kelp and nearshore zones. Chartreuse White and Green Silver shine in clear water. Super Glow and Zebra Glow add visibility at depth or in low-light conditions.
• Let the fall do the work: The Flat-Fall's action is in the drop — free-spool on a slack line and let the horizontal wobble trigger the bite. Most strikes happen on the fall, not the retrieve. Resist the urge to jig aggressively, especially when fish are being selective.
• Use the 100g as your starting point: When you're not sure which weight to run, start with the 100g. It's the most versatile weight in the lineup — if fish are shallow and the jig falls too fast, drop to the 80g; if you're in deeper water or stronger current, step up to the 200g or 250g.

FAQ

Does the 100g Butterfly Flat-Fall come with hooks?
Yes — the 100g comes fully rigged with two Owner dancing stinger hooks on a PowerPro 250 lb assist cord. It's ready to fish straight out of the package with no additional rigging required.

What depth range is the 100g best suited for?
The 100g is most effective in 50–200 ft of water in light to moderate current. It's versatile enough to cover nearshore kelp beds and mid-depth offshore structure. In deeper water or stronger current, step up to the 200g or 250g to maintain the right fall speed and reach the zone efficiently.

How does the 100g compare to the other Flat-Fall weights?
The 80g is the lightest and slowest-falling, best for very shallow inshore water. The 100g is the most versatile mid-range weight, covering 50–200 ft across a wide range of species. The 200g and 250g are suited for deeper offshore water and stronger current. The 350g targets big bluefin and ling cod in deep water and ships unrigged; all other weights come rigged with Owner stinger hooks.
