Williamson Koika Jig 5oz (150g)

The Williamson Koika Jig 5oz (150g) is a premium slow-pitch metal jig designed to imitate the erratic movements of an injured baitfish, making it an essential lure for serious saltwater anglers. Featuring a center-balanced body and innovative asymmetric keel design, the Koika Jig produces an aggressive darting action on the lift and a natural horizontal flutter during the fall, effectively triggering reaction strikes from predatory fish.

The heavier 150g model is ideal for fishing deeper water, stronger currents, and offshore structures where maintaining lure control is critical. Built with premium hardware, a highly reflective holographic finish, and a razor-sharp VMC® assist hook, the Koika Jig delivers exceptional durability and fish-catching performance in demanding saltwater environments.

Technical Specifications

Center-Balanced Slow-Pitch Design

The Koika Jig's center-balanced profile allows it to fall naturally through the water column while remaining highly responsive during rod lifts. This balance enables anglers to maintain precise lure control, even when fishing deep reefs, offshore pinnacles, or wrecks.

Erratic Predator-Triggering Action

Its asymmetric keel design creates an unpredictable darting movement during the lift, followed by a slow, horizontal fluttering descent when paused. This wounded baitfish action keeps the lure in the strike zone longer and encourages aggressive reaction strikes from nearby predators.

Built for Offshore Performance

The 150g weight makes this model particularly effective in:

• Deep-water reefs

• Offshore pinnacles

• Wreck fishing

• Moderate to strong current conditions

• Mid-water pelagic presentations

Its additional weight allows anglers to reach productive depths quickly while maintaining excellent lure action.

Premium Saltwater Hardware

Every Koika Jig is equipped with premium components designed to withstand hard-fighting saltwater species:

• Razor-sharp VMC® single assist hook

• Heavy-duty split rings

• Armored assist braid

• Corrosion-resistant hardware

These components provide dependable performance when targeting powerful offshore predators.

Holographic Attraction

The embedded holographic foil finish reflects light from multiple angles, producing intense flashes that closely imitate distressed baitfish scales. This visual attraction is particularly effective in deep water and varying light conditions.
