Custom Painted 131 Square Bill 1.5 Crankbait

The 131 Square Bill 1.5 is a custom-painted shallow-running crankbait built to trigger aggressive reaction strikes from brown trout, salmon, bass, walleye, pike, and other freshwater predators. Designed with a hard deflecting square bill and proven fish-catching color patterns, this bait excels around rocks, wood, weed edges, docks, and shallow structure where predatory fish feed aggressively.

Each lure is custom painted by Captain Jim Chamberlin of 131 Custom Lures using proven color combinations developed on Michigan inland lakes, rivers, and Great Lakes fisheries. The Square Bill 1.5 delivers an erratic hunting action that imitates wounded baitfish while allowing anglers to efficiently cover water and locate active fish.
