Overview
The Reaction 9.99 is a 3/8 ounce lead swing jig sold in a pack of five, finished in black. Swing jig designs separate the head and hook on a hinge for extra action on the fall.
The swing jig category is a specific technique style: rather than a fixed hook shank, the head pivots to add movement other jig styles do not produce. At 3/8 ounce, the weight fits mid-depth presentations rather than deep vertical jigging or shallow finesse work.
- Lead swing jig, 3/8 ounce
- Five jigs per pack
- Black finish
- Hinged head-and-hook design for added action
Who it's for
Anglers already using swing jig technique who want a 3/8 ounce, black finish option in a five-pack. Not the pick for anglers wanting a fixed-hook jig or a different weight class.
Strengths and trade-offs
Drawn from this product's published specifications.
- Pivoting swing jig design adds fall action a fixed head lacks
- Five jigs per pack
- 3/8 ounce weight suits mid-depth presentations
- Single color and weight option in this listing
- Not suited to deep vertical jigging where heavier weights are needed
Performance notes
The swing jig's hinge between head and hook lets the hook swing independently on the fall and retrieve, producing a different action than a rigid jig head. At 0.38 ounces per jig, it sits in a mid-weight range suited to moderate depths rather than deep vertical presentations.
