Williamson Vortex Speed Jigs
The Williamson Vortex uses opposing convex sides to create an erratic, darting action that triggers reaction strikes from species that ignore standard jigs. The hydrodynamic shape cuts through the water column fast on the drop and flutters on the pause, mimicking a wounded baitfish. Two weights cover most jigging situations: 100g for moderate depths and lighter current, 150g for deeper water and stronger flow. Multiple color patterns match forage from sardines to bunker. Effective for vertical jigging, speed jigging, and casting to surface busts.
- Hydrodynamic design with opposing convex sides
- 100g and 150g weight options
- Erratic darting action on the drop and flutter
- Assist hook included
- Multiple color patterns available
The Jig That Gets Bit When Others Do Not
Standard diamond jigs and knife jigs catch fish. But when the bite slows down and fish are marking on the sounder without committing, you need something different. The Vortex's irregular action on the fall triggers strikes from fish that have seen every standard jig presentation.
The opposing convex sides create unpredictable movement that fish read as a wounded baitfish. Tuna, amberjack, grouper, and snapper all respond to the erratic flutter. Speed jig it vertically, yo-yo it off the bottom, or cast it into a surface blitz. At $14.99-$21.99, losing one to a reef snag does not ruin your day.

Hydrodynamic Vortex Shape
The opposing convex sides are the key to this jig's action. As it falls, the shape creates turbulence that makes the jig dart and flutter unpredictably. Fish that ignore a straight-falling diamond jig will crush a Vortex because the erratic movement triggers their predatory instinct.
Two Weights for Any Depth
The 100g handles depths to about 150 feet in moderate current. Step up to the 150g for deeper structure, stronger current, or when you need the jig to punch through surface chop fast. Both sizes cast well and sink quickly so you spend more time in the strike zone and less time waiting.
Versatile Jigging Styles
Speed jig it vertically for tuna and amberjack. Yo-yo it off the bottom for grouper and snapper. Cast it into surface busts for mahi and bonito. The Vortex works with fast retrieves and slow drops alike, which makes it a do-everything jig for offshore and nearshore applications.
How to Fish the Williamson Vortex Jig
1. Select your weight based on depth and current: 100g for shallow/moderate, 150g for deep/strong
2. Attach the jig to your leader using a split ring or solid ring connection
3. For vertical jigging, drop the jig to the bottom or target depth and work it up with sharp rod lifts
4. For speed jigging, use fast cranks and rod sweeps to make the jig dart erratically
5. Let the jig flutter on the pause. Most strikes come on the fall
6. For casting, throw into surface activity and retrieve with a mix of fast cranks and pauses

What species can I catch on the Williamson Vortex? +
Yellowfin tuna, blackfin tuna, amberjack, grouper, snapper, mahi mahi, bonito, and cobia all hit the Vortex. The erratic action appeals to both pelagic and bottom species. Read our jigging guide for species-specific technique.
What is the difference between 100g and 150g? +
100g works best in depths under 150 feet with moderate current. 150g is better for deeper water, strong current, or when you need a faster sink rate. If you only buy one, the 150g is more versatile. See our jigging guide for weight selection tips.
Can I use this for bottom fishing? +
Yes. Drop it to the bottom and yo-yo it up with short lifts. Grouper, snapper, and amberjack all respond well to the Vortex worked near structure. Our bottom fishing guide covers technique in detail.
What rod and reel setup do I need? +
A medium-heavy spinning or conventional jigging rod in the 5-6 foot range paired with 30-50lb braid works well for both weights. Our reel comparison guide helps you choose the right setup.
Does the Vortex come with hooks? +
Yes, an assist hook is included. You can also add a second assist hook or a treble hook stinger depending on your target species and local regulations. Browse our hook size chart for sizing recommendations.
What colors work best? +
Sardine and bunker patterns work in most situations. Pink glow is effective in low light and deeper water. Blue mackerel matches natural forage in many offshore areas. When in doubt, match the color to whatever baitfish you see on the sounder. See our lure selection guide for color strategy.
How does this compare to the Williamson Kensaki Jig? +
The Vortex has a wider profile and more flutter action on the fall. The Kensaki is slimmer and cuts through current faster. Both catch fish. The Vortex is better when you want erratic action; the Kensaki is better for speed jigging in deep water.
